Thanks for the shoutout guys :) Always enjoy your beautifully shot and edited adventures in astrophotography!
Thank you Dylan! And congrats on the 10K subs!!!
@@GalacticHunter Thanks guys! Can't believe it really. Won't be long until this channel hits 10k I imagine!
Loving your series as a new astrophotographer! Honestly, thanks for sharing your successes and learning experiences. I have had a made a lot of mistakes that were frustrating too and your video shows that everyone goes through it. Keep up the great work!
Hey, thanks so much for not throwing this episode out! My vote is for choice 3
Don't worry about your mistakes; if you don't make any, you're not making progress toward improvement. You have clear skies that are relatively close; ours are 2-3 hours away, minimum. Be patient and persevere. Clear skies!
^^^^ this is the truth!
Thanks John! And yes making mistakes is a good way to progress and that's why we sometimes should embrace them :)
A mistake is not a mistake if you learn from it. Some of the best discoveries has been found by “mistakes”. You graciously share all of your knowledge with your viewers and for that I thank you. Another great TH-cam astrophotography channel is AstroBackyard and of course you forgot to add the best channel of all...Galactic Hunter! I always look forward to seeing new videos posted on your TH-cam Channel.
Thank you Gregory for your very nice words. You make a very good point about discoveries found by mistakes, you are absolutely right! :)
Great video. I like the fact you are so natural. I enjoyed going on the journey with you. Seeing that other people make mistakes is refreshing as I have suffered with similar issues in the past.
I follow Chuck on you tube so would also recommend him, he certainly knows how to use the ASI1600.
My vote is for M8 the Lagoon nebula, let’s see what your asi1600 can really do!
Thank you Mike! Making mistakes is a huge part of learning astrophotography :)
You can see the outer ring of Owl. Thats nice. Very good image.
Yes that's pretty great, we didn't expect that!
Lovely video - beautiful music. Thanks for sharing, because I feel like you somehow brought me there with you and I it was a kind of journey.
I will add your video's are really good and informative because your basically talking in layman's terms,easy to understand and not too technical.
Thank you very much, we indeed try to avoid being too technical in our videos and tutorials.
Cool gear guys! I dig the Polaris/telescope shot. I'm glad to see you found your "mothballs" and didn't scream. LOL.
P.S. I wouldn't be so hard on yourselves about how your images turned out. I think they are amazing. You have no idea how lucky you are to be able to go out and do this!
Thank you! And yes, no screams this time haha
Beau travail comme d'habitude bonne continuation à vous
Merci James!
The drone footage is very cool. Definitely adds the professional touch to your videos.
Thanks! We really love doing drone shots but also we want to make sure to not over use it for our videos :)
@@GalacticHunter Also I vote M8, a very cool target!
Enjoy your videos! Once you have the ASIAIR programmed with your plan you don’t need to keep your iPad connected. You can reconnect any time to check status. Clear skies!
I vote for choice #2.
Its a nice Video. Because it shows that not everytime all is running ok. But the Resuld is very nice too.
Next Night - next chance 😄👍👍. Greatings from Germany
Thank you :)
I follow your channel as well as AstroAddict, Astrobackyard, Dylan O'Donnell, Chuck's Astrophotography, Roswell Astronomy,
Astrophotography Tutorials, Peter Zelinka, Pedro Ré (one of the best Portuguese astrophotographers).
I think one day you have to think of a Rasa 8 "(I only have one WO ZStar 61), I also want one, but I have a little girl like you. It's always more difficult.
I prefer M8, nothing better to compare DSLR vs ZWO 1600 MM.
Thank you for sharing one more video.
Clear skies!
Thank you Tiago! The RASA 8 sure is very popular at the moment. We just upgraded to our new camera so we'll wait a bit before getting a new scope.
Maybe think about buying some infrared LEDs and recording night shot with full spectrum camera. I mean when you're looking through eyepiece, it looks kinda silly when you use such strong white light to let camera see you.
Yes, a night vision camera is in our "wish list" for the future, that will definitely help.
Love your videos!! Thanks for posting all the different ones.
Hi guys nice episode! I am fascinated about the Owl Nebula since a while, look how it stands from the darkness in that well shaped impressive blue! Is like an oasis in the middle of the loneliness...
I was not yet abble to see it visually in my sub-urban skies but maybe one day in a darker sky. After seeing the veil nebula with OIII filter anything could be possible!
I vote for M8 to compare and see how far better could be your new camera.
All the best!
Thank you Ricardo! The owl nebula is often overlooked but is indeed a beautiful object :)
@@GalacticHunter I finally have great news! 2 weeks ago I saw able to see the Owl Nebula + M108 in my 8 inch f3.9 newtonian. The sky was just sub-urban, but the Owl Nebula was really nice and bright, almost perfectly round like a cookie there. The darker "eyes" were there, but not completely evident....
i follow your adventure in english and french ! great video !
Haha merci !
Awesome video👍🏻, vote for M8
Thank you!
I don't know anything about astrophotography, but I love your videos. I love that you are honest about your mistakes. I look forward to the next video.
Thank you very much Robb! We'll always show both our mistakes and successes :)
Hey guys, welcome to mono imaging ;) haha backspacing can be quite the ordeal.
I shoot on a very similar setup, same camera, and FW, different newt. One tip: Put the filters as close to the sensor as you can. IE leave it attached directly to the camera. If you were to put the spacer where the FW was, it's very likely you'd get bad vignetting. Instead, use the adapters provided with the camera and fw, and put the super thin adapter on the telescope side of the fw so you can attach both spacers to the other side (opposite the camera) of the FW. You will get the same overall backspacing, but keep yourself from introducing vignetting due to the filters being too far from the sensor.
The ASI FW was designed to be mounted directly to their cameras that puts filters in an optimal position. If you were using 2" filters this may not be such a concern, but with 1.25" filters and the ASI1600 it can become a problem.
Also, in regards to framing. You should really capitalize on the ASI Air's ability to plate solve. I'm sure you're familiar with plate solving, but it really simplifies the framing. With plate solving, the camera will snap an image, calculate where you are, tell the mount, and then when you tell it to slew to an object it should be right in the center of the frame. From there you can simply move manually to adjust framing. Many higher level acquisition programs have framing assistance where you can set it up to automatically frame however you'd like, but I don't think the Air has this.
Time is super valuable in the field. Make the most of it and get your plate solving setup so all you need to so is solve, focus, shoot.
Cheers!
Hi and thank you for your comment! Several people mentioned the same thing about backspacing and how we should attach the camera directly to the fw. We are now making sure to follow that advice and have done so just last night when we went to image, and yes, there was no vignetting!
As for plate solving, you are totally right and we can't believe we didn't use that during this episode seeing how framing was the main topic haha! We are using the ASIAir and it does have a plate solving option which works great, we just need to use it more often.
Like you said, time is valuable. Thank you!
Nice shot of M97 and M108, looking forward to seeing your planetary shots
Great video guys! I appreciate the work you guys put into making these high quality videos. I also like how you guys decided to keep the data/video despite the coma issue.
Thank you! We honestly thought it wouldn't be as bad after processing it but oh well. We'll get a better image of these in the future eventually :)
Great video guys. Choose #3
Thanks!
Have you heard of Trevor at Astrobackyard? Oh and look at Tim from AstroAddict
Yes for Trevor we wrote it as text in the video, as for Tim, you're right, forgot about AstroAddict as well! There are so many great channels out there :)
U two are awesome, loved ur video
Thank you!!
Nice job guys!! Been out of the country with work, and returned to see this!! Wonderful!! Keep up the good work!!
haha thank you Kurt!
Good video, thanks for the tips. All three choices are good. I vote #2.
Vi seguo dall'Italia, complimenti, continuate così
Super cool video my friend's ☺👍:)
Thank you!
Many thanks guys for another great video! You really are a true inspiration for me in this hard, but fantastic hobby! I vote for M8🙂
Thank you very much Francesco!
Neat - thanks guys! Next target - anything will be fine - good luck!
Thank you!
Just another quick one.Iv'e been observing the double cluster in perseus,very recently with aforementioned instruments,and found the views through them of the subject not as spectacular as i remembered years ago when i used a skywatcher 6"refractor.Through that they looked like two large diamond clusters and showed them to my eldest daughter of which i now have three.This is a reason iv'e bought the 6"reflector.The reflector is unbranded but the price was still unbeatable,i'm not expecting it to be bad because it's made in china as all of the good stuff comes from.I will hasten to add i do love skywatcher instruments.
Great job! regardless of the coma.
Rough guide for planetary I saw on ZWO Facebook was use a telescope with F ratio approximately 5 X pixel size in microns. For ZWO 290 mm 2.9 u that gives roughly F 15! You’d need to use something like a 4X barlow. I have a classic achromat F15 refractor and will try in planet season. The resolution for the 90 mm objective worked out to a bit over 1 arc sec.
Awesome video :). I would vote for the M8 for ASI 1600 camera.
Thank you!
Great video, making mistakes is how we all learn. I vote Omega nebula.
Thanks! And yes, we'll be showing the mistakes we make, especially with this camera since we really want to show our learning curve from DSLR imaging to CMOS/CCD
Obrigado ao casal, sempre que posso assisto os vídeos, sucesso ao canal, um abraço do Brasil. Sou apaixonado por astrofotografia.
Great video (as always) Guys!!!! Choice #2 for me!!! Greetings from Italy :)
Thanks Nicolò :)
Keep up the great work
Cheers
From Oz !!
Live and learn... great episode!
Do you guys do flats? Does the ASIAIR do plate solving?
Cheers
Thanks Sergio! We still haven't taken the time to make a flat library... And yes the ASIAIR does plate solving.
Hi guys, one suggestion: even with the cap on, or with the camera upside down or any other way to cover the camera sensor, you should take the darks in a completely dark room. Otherwise, somehow, some photons will eventually make it to the sensor - specially in longer darks - and the dark frames won't be as effective. (I own the same camera)
Great videos, always!
D
Planetary with the 1600 is not the best, due to the relatively large pixels, but both Lagoon and Omega will look terrific!
For planetary I recommend you the cheaper non-cooled asi178mm.
@@dgodiex Thank you for the advice on taking darks, we'll do that next time! As for the planetary imaging, yes that's what we're afraid of, the 178 does look better for that kind of target.
@@GalacticHunter Another good one , though more expensive, would be the 183mm-cool, - same pixel size as the 178 - and you would also have a great camera for small deepsky objects too, or for super detailed close ups of larger ones.
Clear skies!
Great video 👍🏼
Mystery planet !
Thanks!
You’ll want the filters as close as possible to the camera. The backfocus requirement will be dependent on the field flatterer, which I think you are using? I believe the baader uses 55mm...but some flatterers will vary. Good job on the video.
Thanks for the tip, we'll put the adapter on the scope side next time!
Nice vid , question though, did you not use a coma corrector when using the DSLR and can this corrector be included in your imaging train with your new camera ?
For framing I always try and get more than one object in the view and do this using APT and platesolving (couple of vids on my channel to show how to do this if your curious)
For a choice of the next target I would say No.1, then we can see the difference between the two cameras :)
Thank you! We did use a coma corrector with our DSLR, and we use the same one for the ASI 1600MM. The problem here was that with the ASI, we needed an extra adapter between the camera and the filter wheel, so even with the coma corrector, there is coma showing due to the lack of backfocus. We photographed M106 the night after the Owl and by adding the adapter, all the stars are round and sharp.
Great video. I choose #2, M17.
nice video well done.
Thanks!
I do enjoy your videos and your personalities 🙂 Do you do your own drone footage for these or get it elsewhere? It really steps up the professionalism of the videos . All the best to ya's
Thanks Tom, we do our own drone shots :)
@@GalacticHunter awesome ! They look high in the air , almost like a helicopter
FINALLY, I've been waiting for a while but it was worth it in the end thanks you two.
P.S: I was able to see Jupiter for the first time and I'm shooting for Saturn next, Clear Skys!!
P.S.S: I think it's time for the Mystery Planet
Thank you Mathew, and sorry about the long wait! Good luck with Saturn, such a beautiful planet to image.
I vote 3
You guys really need to invest in a good red light... It will do wonders for your viewing. Cool video- Keep up the good work!
We have a headlamp that does red light which we use all the time but it's not strong enough to light up an area when we make videos :/
@@GalacticHunter I'm curious- How often are you able to get out and shoot and view without making videos?
@@AstroDenny Probably about once or twice a month. We could go much more often but work makes it very difficult to find time.
Great video as always! I vote for M8 haha! I tried planetary with my 1600mm and didn't have the best luck because of the framerate. I just got a 290mm for that and hope to try it soon
Thanks! We wonder how the 1600mm will handle planetary. Hopefully it will at least be better than with our DSLR.
Great,thanks for the reply.I also forgot to mention my small collection of bino's which really are great for observing casually.A 10x90x60mm,15x70,25×100.The 15x70mm really are ideal the images through these are really sharp.Thanks again,i should mention i'm 64.
We have one pair of binos (which we got before buying a telescope), they are 20x80, which are really nice to observe M31 or M42 or any other large DSO really, but they are too heavy sadly and a bit of an overkill when it comes to focal length.
I’m voting for Messier 8
Great video.
Do y'all ever camp overnight for your shots?
Now that we have a new car I (Antoine) sleep in the trunk while imaging all night, we haven't camped and imaged together yet 🤔
@@GalacticHunter Dunno what the closest Bottle class 2 skies are to you, but Afton Canyon campground between Baker and Barstow is as bit under 2 hours from you. No lights in the campground, so you would just need to wait for the other campers to go to bed.
Great video's.I can't do astro-imaging myself but love visual astronomy.Just waiting on a 6"reflector to go with my small collection of telescopes including'60mm refractors and 70mm refractors 41/2" reflector.I buy them very cheaply on ebay and they do the job very nicely.The 6"only costing me £65 complete and in the box.
Wow that's insane! We rarely take the time to do visual astronomy, but it sure is always nice to relax and just observe.
I'm not familiar with the asiair software since i don't have an asi camera but i would like to know if it has plate solving. It can be real time saver for finding and centering objects.
Yes it does, it works pretty well.
cool
All the adapters you need comes with the asi1600, and it's best to put them between the filter wheel and the telescope, not the camera and filter wheel.
Yes they do, we just didn't think it through enough as we weren't sure what we were doing. We imaged M106 the next day and had no problem. We put one of the adapter between the filter wheel and camera though, so thank you for your input, we'll place it between the scope and filter wheel next time!
@@GalacticHunter thanks for making some of the more cinematic and entertaining astrophotography videos. The com is a shame but great results on the targets :)
What telescope do you use? Would you ever make a list of all your equipment for us?
Hi, you can find the full list here: www.galactic-hunter.com/blog/our-full-astrophotography-equipment there is a video in there as well :)
Yes I like the stars and stripes, or should I say nebulae and stripes.
I vote for #1-M8
Do you all have issues with balancing the OTA and all the other stuff, I do like a fast scope but the mount i have only has 40lb weight capacity.
We never have an issue with balancing or tracking. We use this mount bit.ly/2Y7qi5L which is way enough for our load and the accessories.
Could you guys do a guide on the ASI air? There really isn't much out there
We have started writing a review for it, but it is taking time. The plan was to add a short guide in that review. We have so much to write and so little time with work/college :(
#3 Mystery planet
Both drawings get A for effort!
Haha thank you!!
bonjour a vous cette video a l aire d être très intéressante dommage qu elle n est pas en francais bon ciel a vous et a la prochaine video
keep going :)
Antoine & Dalia, The only couple doing astrophotography together adds a Yin and Yang quality which I totally love. Very honest about their feelings as they image.
Thank you very much! We're thinking of making a "Astrophotography as a couple" video in the future :)
I guess if you're out there in California that would look like a surfboard.
Would like the Lagoon Nebula, but then Jupiter opposition is coming up which would be the perfect opportunity to do some lucky imaging with your new cam.
Although, you could probably squeeze in an imaging run for Jupiter the same night you're doing M8 or the Omega Nebula. Imaging planets only takes a few minutes, after all.
Don't shoot videos longer than three minutes for Jupiter, or the planet's rotation will smear the details in your final image. There are ways around that (WinJUPOS), but that might be a bit too much when you're not that experienced yet.
Also, use www.shallowsky.com/jupiter/ for finding a good motive to shoot (like the shadow of a gallilean moon on Jupiter or the GRS).
Thank you for your tips on imaging Jupiter! We almost never do planetary imaging so we really appreciate the help :) Maybe we can squeeze it when doing our next target.
@@GalacticHunter Happy to help.
If you're unsure on what software to use for post-processing:
Stacking: Autostakkert!
Processing the stacked image: Registax
I've never worked with PixInsight so i don't know how much of that sort of functionality the app provides.
@@mrspidey80 Thank you! We'll write this down for reference.
I chose number 2
i loveyour videos, but i would strongly suggest let the girl do the talking.. she has a knack for it.. she could do the narrations.. shes got a voice for it as well.. just a suggestion. its less distracting. and more appealing!
Go for Omega nebula
#2
you need OAG
Messier 8
