- Some planets, deep sky objects and stars, seen through an 8" Dobsonian telescope. To capture the planetary images I used the Svbony SV105 camera, coupled to a 3X Barlow Svbony. The images were acquired without tracking and guiding. All images were post processed in PIPP, AutoStakkert! 3, RegiStax 6 and Photoshop 2020 software.
For images of deep sky objects, I used the prime focus method (eyepiece projection) using a Canon EOS Rebel T100 camera coupled to a T2 ring with an extension tube, using a SkyWatcher Super Plossl 25mm eyepiece. All images with a single exposure of one second in RAW format.

holy shit ... its my first day of trying to learn about astrophotgraphy.. these are incredible... i have so much to learn. i have bought a celestrom a130 and havent a clue what im doing but here goes. Loving your content.
Hi! Start by planetary astrophotography is a smart decision! Is less expensive and very fun! Thanks for the kindly words and for your support! Clear skies!
@@AstronoMinas thanks for thr reply. I'll start there so. Excited to get into it
Thank you for taking the time to make this video.
It's a plesure share a little of my backyard night sky with you. Thanks for watching! Clear skies!
What a 8-in dobsonian apartura telescope work with the planetary astrophotography set in your description
All images were taken with a 8 inch dob. Thanks for watching and for your support! Clear skies!
I know what you've burnt the midnight oil to take these excellent pictures. I've given up the desire to buy a scope to see them with my own eyes because it won't be this good. Thank you for helping me come to this decision.
Hi. Observe the planets by the eyepiece glass is more exciting. Take good pictures is nice to share with others astrophotographers, but visual astronomy covers the entire experience. My best nights were leaning over a telescope. You should try it! Thanks for watching!
One good thing about refractor telescopes I like is that stars don’t just look like bright lights you can see detail on them that’s why I have a refractor and a reflector they both have their strong suits
Hi! Refractors are petfect for DSOs and Reflectors are better for planetary. Thanks for watching and for your support!
WoW...
Amazing pictures..
Thankyou for sharing..
Hi! Thanks for watching!
@@AstronoMinas you bet... you provide us with Great pics most of us ( myself included) cant obtain ourselves
It's a pleasure! Clear skies!
Im preparing to buy one
Im so excited to see this
(The live view of course)
Hi Simon! You will love it! It's a very nice and versatile telescope! Thanks for watching!
When i will get the telescope i will transform my chanel to astronomy videos
Very nice! Clear skies!
Great results! But how much frames did you record for each planet or how long was the video and did you capture the video in sharpcap?
Hi. For Saturn and Mars I used 11 videos of 45 seconds. Using the autostakkert 50% best frames (11000 stacked frames). For Jupiter 3 vídeos of 40 seconds (1500 stacked frames) to avoid rotation. Thanks for watching!
Hey. I know it’s been a while, but the Orion Nebula is so bright you can use a planters image stacker for it. I use the ASI CAP software, it’s free to download and use. I’ve taken photos you wouldn’t even believe with it and a 3000 frame video stacked. You can see all sorts of color and cloudiness. Happy star hunting.
Hi! For DSOs I am using refractors with equatorial mounts. There is a entire playlist named DSOs in the channel's page, please take a look. Thanks for watching and for your support! Clear skies!
Ansioso para a chegada do meu telescópio gso dobsoniano de 8". Falo daqui de Minas tb. Ótimas capturas vc fez! Parabéns!
Bom dia Saulo! O dobsoniano 8" é o equipamento mais versátil que existe. É leve, relativamente compacto, tem boa ampliação, funciona bem para sistema solar e objetos de céu profundo. Aliado a um um céu escuro é certeza de boas observações. Obrigado por assistir!
Wanna see how minute we humans and our problems are watch this video
Hi Suhan! Thank you very much for your support!
@@AstronoMinas Always Welcome
Really good
Hi! Thanks for watching!
It's amaaaaazing!!!
Hi. Yes, it's amazing! Thanks for watching!
This comment may be a little late how about the technical specifications on the eye pieces you used
Hi. All my eyepieces are Celestron Omni Series and I use a Skywatcher 25mm 52° too. Thanks for watching and for your support!
Excellent work. Your planet images came out especially good. You should try imaging some binary stars. Keep up the great work.
Hi David. I had try it. Dobsonians are great spliting stars but eyepiece projection is a really trick method in an 10 inch. Thanks for watching!
Great job!
Hi Rob! Thanks for watching!
Thanks
Hi. Thank you for watching!
Beautiful
Thanks for watching Michel!
You can get those without a tracking mount?
Hi! It's a little harder but is possible! Lol! Thanks for watching and for your support! Clear skies!
Man i just saw the Sun through my 8" for the first time today ... crazy crazy looking thing
Hi! I hope you used the right filter! Lol. I am kidding! The 8 inch Dob is the most amazing scope created. Thanks for watching and for your support!
@@AstronoMinas lol yes i ordered the cover replacement with a 15 lens i think it is .. anyways it looks unbelievable i could see the dark spots ...
I use a 60mm to observe the sun. The 8 inch is a super overkill scope for solar spotting. An advice: don't try to get into the solar astrophotography it is a endless money consuming trap. Lol.
@@AstronoMinas ya what im finding out is that you need to be on the schedule of the planets and when you can see them so if at least the wife can look at the sun during the day then i win ... trying to maximize the use of it
Genius.. Never done this with my 10 inch goto dob.. Focus failed (fell apart) and difficult to balance with DSLR attached..
Hi! It's a DSLR is really heavy to the original focuser. You could upgrade to a more reliable and robust dual speed focuser. Costs 3 times than the original price, but it lasts forever. Thanks for your support!
Wow, I was truly amazed by your videos capturing the planets! The details and clarity were incredible. I'm curious to know if the live view through the telescope looks just as breathtaking as what we see in your videos. Can you please confirm if the live view provides a similar visual experience? I got a 4 inch Newtonian that is pretty bad so I’m thinking about buying this one.
Hi Isac! Depending the seeing conditions, the look it is better. Thanks for your support!
@@AstronoMinasis that true? I thought our eyes can’t process those colors live viewing.
In DSOs they don't... in planetary is very easy to observe colors.
Awesome
Thank you for watching!

Hi! I will release a new video with a good surprise soon! Thanks for watching and for your support! Clear skies!
Ι have recently bought this telescope! The still images that you have taken are absolutely amazing! How do you do that? You can even see the ice caps on Mars!
One more question: have you ever tried the Andromeda Galaxy, or any other galaxies? How do they look? I saw your video with the 10 inch, is it a big difference? Thank you!!!
Hi! The Mars picture was taken in october 2020 when Mars was closest to the Earth. It is s a stacking of 1400 frames from a 3 minute video. I can see many more galaxys through the eyepieces than I could capture with a camera. The objects looks much more exciting in visual astronomy sessions, but some details like braces and gas clouds are only visible in post processing. The 10 inch shows much more DSO's. I know it´s only a 0,5 magnitude than the 8 inch, but is much more faster F/4.7. This means more light. For example: the 10 inch transforms the M15 cluster in completely separated stars. The 8 inch stay a half step back: the cluster looks fuzzy yet. Andromeda is great in both, but the 10 inch shows the neighbor galaxys a little better. I tend to use the 10 inch for DSO and the 8 for planetary. Jupiter and Saturn are not so good to image yet. Andromeda will be visible around here only in august. Thanks for watching!
Sou de Itamonte MG. Parabéns pelas capturas. Namastê
Olá Alexandre! Vizinho, aqui pertinho! Obrigado por assistir!
Thanks for posting. Is your Canon camera modified for astrophotography?
Hi Ian. No, it's a stock camera with the chepeast original kit lens without tracking, guiding and no stacking. I only did a Photoshop streching to enhance the contrast and remove a little light polution. Thanks for watching!
Thanks for the reply, that's set me thinking!!
It's a Bortle 4 sky.
For the live video footage, would it look clearer without the camera?
Hi! If you are talking about observing through the eyepieces, yes. Is very clear and sometimes better than in the vídeos. Thanks for watching and for your support!
I have an 8” Dobsonian on back order. I can’t wait to try it out. Will the images of the planets be that clear through the eyepiece? Or is this mostly editing?
Hi John. Sometimes the images are better through the eyepieces. With good seeing and a good collimation an 8 inch dob is one of the most capable visual astronomy tools. Nice choice! Thanks for watching!
Planets look better in eyepiece and dso in images. Though dobsonian are not meant for astrophotography
mee too cant wait too get mine and see through the eyepiece
Hey, did you use a tracking motor for these images or just the scope and camera
Hi. No, my dobs are not motorized. I do the tracking manually with many short videos. To this technique works your fiderscope needs to be dead spot on and the base very smooth. This way every time you need to put the planet back to tge afov the time lost is very short. Thanks for watching and for your support! Clear skies!
@AstronoMinas thanks so much 🙏 you earned a new subscriber, this is definitely going to help my decision
Thank you very much! Glad in help you someway!
does it look like this with your eye? and what equipmenr are you using?
Hi. It's better using eyepieces. It's possible to see more surface details, surrounding stars and moons. For this vídeo I was using a Skywatcher 8 inch Dobsonian, the SV105 planetary camera and a Canon Rebel T100. Thanks for watching!
I see video's like this and it makes me want to buy a Dobsonian.
I'm looking at 6 inch and buy a nice barlow, is 2x or 3x better?
Hi Vicky. 6 inch is a good start point. Barlows are great but the magnification depends the seeing conditions, type of object and magnitude. The 2X is a more overall and the 3X more specific to planets and moon. Thanks for watching!
Amazing view. This is a 300x magnification (planets)?
Hi Del. It's an image scale equivalent to 500x. Thanks for watching!
thats a bit too much:D 200x is a perfect magnification for my experience with a 6mm eyepiece 66 degrees view
The focus on my 10 inch Skywatcher flextube failed completely in the minus 10 to 22 degrees celsius, here in Iceland. Bad design, metal against metal. Had to buy another focuser and replace it, just in time for the planetary-season to be over. Very frustrating.. I also attached an electric motor to the new - Skywatcher 2-speed - focuser. Hope it doesn´´t fall apart again next fall or winter..
The dual speed focuser has much better design and durability. It uses the rack and pinion design. It doesn't slide off and stays in focus even with a heavy payload. Give it a try:

Is your dob goto? If not, do you have any tips for keeping it in view while capturing? I've been Trying to capture videos myself and it has proved difficult without tracking.
Hi! It is not goto. I only center the object the better possible using the finder and take only an one second exposure at ISO 3200 or 6400, depending the target. Thanks for watching!
Is watching with your naked eye the same quality as a stacked image?
Hi. It's better. It's possible to see more surface details, surrounding stars and moons. The processed images are restricted to camera and software limitations. Visual planetary astronomy in a dobsonian is amazing! Thanks for watching!
What eyepieces are you using?
Hi! Generally I use the skywatcher 25mm 52° and Celestron's Omni Séries 12mm and 6mm with a 2x barlow lens. Thanks for watching and for your support!
For just viewing can you see this good through the eyepiece ?
Hi. Yes, sometimes it's better through the eyepieces. Planets are definitely better. Thanks for watching!
Hello I plan purchasing a dobsonian 8 inch. what camera would I need to capture things like this and how would I attach it. is there links on what you are using? also great pictures man 👍🏼
Hi! It is a great telescope. You'll love it. I am using the ZWO ASI 678MC at this time. For this video I used the Svbony SV105 entry level planetary camera and my Canon T100 with T2 adaptors. The SV105 is very affordable for bigginers and you attach it straight to the 1,25" telescope focuser. Thanks for watching!
Hey please answer this, I want a telescope to understand the sky first and then start astrophotography so many people in my circle and group and youtube videos recommended me an 8 inch Dobsonian but I am confused to choose between an 8 and 10 and I really care about weight and portability because in my city which comes in 8 or 7 light pollution and there are no nearby dark skies, at least in 500 km so could you recommend with your experience which to buy and any pollution filter probably and some equipment with it too but for basic understanding, like lens cap, etc and would it be a big task to collimation of it. And what about the deep sky? Also, I have heard you could see much more than you can capture in detail? true? please answer
Hi. The 8 inch is the workhorse scope. It's light, affordable and portable. The 10 inch is the first "big scope". It's heavy, fast and will take more time to colimate than the 8 inch, but it shows DSO better. Much better? Yes, 0.5 mag it's the difference between see a galaxy or observe it. The 10 inch collects more light too what could help to manage the light pollution ptoblem. I have and use both scopes, the 8 inch is simple and lighter and shows many nightsky highlights. The 10 inch is tricky and heavier. If you choose the 8 inch you will ever ask yourself what a 10 could show better. This is an endless astronomy's forum discution but I definitely grab the 10 inch. The weight, cost and time to colimate worth the views. Thanks for watching!
@@AstronoMinas thanks for you reply what about equipment needed www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=&cad=rja&uact=8&ved=2ahUKEwiy9pLDgePxAhWeH7cAHah2DFkQFnoECAMQAA&url=https%3A%2F%2Fjgroub.wordpress.com%2F2018%2F08%2F11%2Faugust-11-2018-dont-buy-a-10-inch-dob-over-an-8-yet-magnitudes-explained%2F&usg=AOvVaw2bPBYVVeRi9eOP2I-gi0zp
Believe me. The human eye can see the 0.5 magnitude difference. I did the test with 8 and 10 inch side by side with the same brand 25mm eyepiece in both in M15. The 10 inch splits and shows more stars. If you have the money, space and strength to lift weight, take the 10 inch. The equipment you will collect through the years. Always will appear a new necessity. A 10mm and a 25mm eyepieces and a 2x Barlow it's only you need to start.
@@AstronoMinas Thank you
We're welcome!
👏👏👏👏👏👏 muito top vou iniciar na astronomia mas uso óculos aquelas oculares de 100graus de campo podem me ajudar a ter uma visão melhor e mais nítida com um dobsoniano de 12” obrigado
Olá Luis. Eu também uso óculos e optei por me adaptar a observar sem eles. O focalizador muitas vezes faz o papel de ajuste fino que os óculos têm, claro que se o problema for astigmatismo, não tem muito o que fazer. Oculares wide angle combinadas com espelhos com parábola acentuada exacerbam o coma e aberrações na periferia do campo de visão, mesmo com as Tele Vue. Você pode precisar de um paracorr. No meu 10" eu utilizo oculares de 52° sem paracorr e já noto um pouco de coma nas bordas. Para astronomia visual isso não me incomoda, basta manter os objetos no centro. Para astrofotografia isso torna a colimação perfeita essencial toda vez que você for utilizar o telescópio. Se dinheiro não for problema paracorr e um kit Tele Vue 100° ou 110° resolve tudo isso. Obrigado por assistir!
Going to buy a 8" dob sometime soon would you recommend any scope over another. also what lenses would be good to start out with?
Hi Aaron. Every brand has an 8" in its product line. Sky Watcher, Orion, Apertura and many others are very similar. The only advice here is find a scope with a good focuser. At least a 2 inch with the adaptors for 1,25" eyepieces and made of metal. To start the 10mm and 25mm eyepieces and a 2X Barlow lens are fine. Thanks for watching!
Hey I just got a AD8 and I was wondering if you linked the adapter for the camera to go on the telescope in the description? And also does 1 adapter basically fit any/most cameras??
Hi. For the SV105 there is no need to use an adapter. For the Canon eyepiece projection method I had used this: shopee.com.br/amp/Chos-Aluminum-T2-Adapter-Telescope-Extension-Tube-1.25-inch-Telescope-Mount-Adapter-Thread-T-Ring-For-Canon-EOS-Camera-Accessories-i.290387170.11327884101. This adapter only fiis in Canon cameras. Thanks for watching!
What photo editor did you use for these end results.
Hi Mark. I use only yhe Adobe Camera Raw filter in Photoshop, only to correct exposure, contrast and noise. Thanks for watching!
عالی
از شما برای پشتیبانیتان بسیار متشکرم!
hi, did you use any color filters for these images?
Hi, no I didn't. Only the camera and a Barlow lens. Thanks for watching!
After seeing this video I don't know if a 10' dob is worth the extra $200+ ...
Hi! For DSOs worth it! Thanks for watching!
Tbh it really is but think about it hard bro ive been deciding which telescope i want for about 3 months now and ive found the perfect one.
Hi. An 8 inch dob is the most versatile and fun telescope wou will find. You will no regret. Thanks for watching!
@@AstronoMinas yes im getting one too but if i had the space i would get a 10” dob because u see so more detail
Yes, DSO's on the 10 inch is a little better. Not so much, but is enough to split dim stars in Omega Centauri, M13 and M15.
what bortle?
Hi. It is a Bortle 4 sky. Thanks for watching!
What eyepiesies did you used?
Hi. For the planets only the 3x barlow and the SV105 camera. For stars and DSO's a 25mm 52° super plossl using eyepiece projection method. Thanks for watching!
what Bortle level are your skies? clear skies.
Hi Simon. It's a Bortle 4 sky. Thanks for watching!
Why does saturn look clearer than jupiter although he's more far away
Hi. Saturn allows more time filming than Jupiter. Jupiter rotates really fast. One day in Jupiter lasts only 10 hours. If we film more than 3 minutes the image will blur causing lost of definition. This effect is known by blur rotation. This only allows short videos to stack less frames. We have a less detailed image but is possible to see the equatorial bands and storms. Bigger telescopes can compensate this effect gattering more light. In Saturn we can film 15 to 30 minutes without this effect. More frames, more details and better clear images. Thanks for watching!
@@AstronoMinas thanks for everything!
You're welcome!
You guys have telescopes? 😔
Hi! You can look at the sky without a telescope. The idea behind this channel is to share my views with those who can't. Thanks for watching!
@@AstronoMinas thanks for the video, the images are fabulous
What lens are you using? I have the standard 25mm plus a 2x and 3 x lens but I still only get dots when focusing on planets.
Hi Matt! For planets I use only the camera and a Barlow lens, actually the GSO 2,5X. Thanks for watching!
