    Thanks! ** Exactly** what I want to do - visual/EAA combo! I got a used C9.25 that came with 2” EPs (just the cheapo Celestron set) that give a huge fov compared with the old 1.25”s that came with my 40 year old C8. Would the 2” EPs fit that flipper thingy? Also, what are you running SharpCap on - did you say a SurfacePro or something?

    • @AVTAstro

      Hi, first off thanks for the Super Thanks! Most of the flip mirrors are a 1.25". The one in this video is an older one that Meade made that is a 2"(Meade #647, you can only get them used). Software wise I used SharpCap Pro and the Surface pro is just my laptop of choice. Any windows laptop will run Sharpcap. Sounds like you trying to put together a nice EAA setup! Let me know if you have any other questions. Vlad.

    Hi Vlad, this is a great video, thanks. I've got an F11 C14" and am planning to do some EAA alsop. Like you, I'm an mainly visual observer.
    I'd love to see a video about your 24" Dob! I imagine you'll need a new (larger) observatory for that sucker, right?! Clear skies

    • @AVTAstro
      @AVTAstro  ปีที่แล้ว +2

      Very cool, yeah EAA will be amazing with the 14". Don't be scared to try it at f/11 if you have the appropriate mount. I will make a video about the 24" once I have a bit more time with it. But yes the current observatory is maxed out size wise with the 12" ACF that I have it in currently.

      @@AVTAstro Yeah I look forward to seeing it! I have my 14 on a CGXL which so far I have really enjoyed. I've had to do a few adjustments to backlash as the mount is permanently outside and ius affected by temperture but apart from that all good. I do have an F7 reducer for the 14 but I think I will go F11 for the EAA, especially because the exposures will be much shorter! Clear skies Vlad

    Hey again Vlad - I’ve (thanks to you again (my first stacked image!)) been using the Meade flip on my C9.25 with the 6.3 reducer into ASI Air plus. Been having a lot of fun. I even hooked up the 60mm guide cam that came with it and have been dithering and getting good results. I tried the Hyperstar once but I’m back here as I really prefer the visual/EAA combo (I have your pirate patch). I’d like to try f10 and noted that due to the narrow fov you said you sometimes plate solved with the little one to get on target. Can you elaborate? Could I use my 60mm guide scope with my ASI 294 MC on that? I have a cooled 294MC on order so it will be spare. Is it possible to find an object with a goto/solve on that one (or do you use the big one?) then Observe using the flip and finally EAA the target? I guess with the ASI Air plus I’d have to swap main guide cams each time but I’d be ok with that (or even have SharpCap as well)? Rgds, Patrick
    21:08 - are you running SharpCap on both cams?

    • @AVTAstro
      @AVTAstro  9 หลายเดือนก่อน +1

      Thats exactly what I do. You need to accurately align the small scope to the big scope(you will need to have centering screw type rings to do this). Use the non cooled camera on the small scope and cooled camera on your 9.25. You need to run two instances of Sharpcap(just launch it twice). I do this with no issues. Hope this helps!

    • @randallpatrickc
      @randallpatrickc 9 หลายเดือนก่อน

      I am currently using the ASI air plus to control the mount as well. What are you using? I don’t think that sharp cap controls the mount - Carte de Ciel (or whatever it was?) do that?

      Unfortunately no matter the amount of money there is no galaxy filters worthwhile. Galaxies are a very broadband object(emit light in all waveleanghts) so filters don't work on them. The only filter is the gas filter to drive to a dark sky site;)

      Thanks for the feedback! Mount wise the g11 is by far the best mount you can get for under $5000. Nothing even comes close. This thing is made in the USA and extremely well. You can call Losmandy in California and talk to the people that make the mount and get any part you may need for it. In order to get a better mount your looking at a $5+ Astrophysics / Paramount / ext.

    • @AVTAstro
      @AVTAstro  ปีที่แล้ว

      Sounds like you are having an issue with finding focus at the correct exposure ay night. If your neighbors light is fairly far away(at least half a mile) that should be about the same as focus in the night sky. At night make sure your pointed at a bright star(maybe Center it with the eyepiece first) and then start adjusting the gain up. Set the exposure to like 1.5sec. You should see the bright star on screen no problem. Focus on that and then you can move onto the dimmer stuff!

I’d given up on the ZWO 585 and gone back to the little ZWO Mini - swapped it with the EP and twiddled the focus a bit. I thought aha! I’m almost there. Pointed at Jupiter - grey screen.. doh!

    Wow I literally just did this last night! I wanted that Edge HD 8 but I settled for a smaller scope C6 and a HyperStar with a ZWO ASI533MC Pro Cooled. Since I live near Chicago (insane skyglow), I wanted a more portable rig to drive out to darker locations. Doing EAA at F2 is insane especially with Sharpcap pro! Since I saved so much money on the scope, I invested in the Radian Triad Ultra F3 (Fast version) filter. I was imaging nebula right before my eyes near Chicago! Yes the FL is low at F2 but that is what zoom in Sharpcap is for LOL. I really like the eyepatch idea! You could use BackyardRED for you computer and it will turn everything red to not mess with your night vision. Thanks for the video. Clear Skies!

      Sharpcap zoom can’t give you resolution

    • @AVTAstro
      @AVTAstro  2 ปีที่แล้ว

      Yes a lot of people start with a fast setup witch is actually a good idea. Fast exposures and tracking is forgiving. But as Bosun has said using the zoom feature in SC does not give you a larger image scale. A good way to think of it is that its like optical zoom vs digital zoom on a camera. The optical zoom is actually giving you a larger image over the sensor. The digital zoom just makes everything more pixelated.

      Especially since you have the flip mirror diagonal (and eye patch). You can visually see the object! Just switching to the camera to record what you see! Same photons as your eye sees. Only enhanced by SharpCap! Great video.

    • @AVTAstro
      @AVTAstro  10 หลายเดือนก่อน +1

      Yeah, for me this is the ultimate way of doing this. It's not easy in a since you do need to keep one eye covered for it to be effective. But especially in my observatory environment it works really well for me. Most objects look better on the screen, but some look better with the eyeball such as open clusters and even some nebula.
