  1. Thanks everyone! I took your advice, and used only one Barlow lens. I also used only 1 minute captures, and I think it helped a lot. I made this animation over a series of captures last night until the fog rolled in. As you can see, the quality is vastly improved. Thanks a lot!! 18066103_633290853523501_6965660471269523456_n.mp4
  2. It's a 17" CDK telescope, so the light takes a trip from the primary to the secondary, then from the secondary to the camera/eyepiece. Those two trips do add to about 3 meters, but luckily the scope can be a little smaller. It is still huge though, and requires a dome!! Here's a picture of it, with me to scale:
  3. hi! I'm using my school's 17" telescope and a Nikon D3200 to record video from Jupiter to stack. The scope I'm using is f/6.8, and I'm using two 2.5 luminos barlow lenses on it, which blow Jupiter up and I think give me around a focal ratio of f/43. The images I've included were captured with a video consisting of 1/30 second exposures at ISO 800. I'm pretty sure I'm not getting the most out of my camera and scope right now, I'm pretty sure I've seen other DSLR users get WAAAY finer detail with similar cameras on much smaller scopes. PLEASE let me know if you have any suggestions... I'll be imaging tonight again, and I'll be sure to let you know how it goes!
  4. Thanks so much! I used autostakkert 2 and pipp, and here is the result for my first attempt at imaging Jupiter! Thanks a lot!
  5. Hi! I've finally been given access to my school's 17 inch telescope, which is a great tool for astrophotography. On Friday, I took about 20 minutes of video (total) from Jupiter, and I was hoping to stack this data in Registax. Unfortunately, when I try to select a 3 minute avi clip of the video, Registax simply stops working! This is agonizing, because I have really good data!! Forgive me though, I'm sure I'm making a newbie mistake, since I've really only done deep sky astrophotography using Deep Sky Stacker. I'm running Registax on Windows 10, and using a Nikon D3200 to shoot video at ISO 200 at 1/30 sec exposures. I then convert the MOV files into AVI's. I've included examples of some decent frames I captured. ANY help is appreciated!!! Thanks!!
  6. Hi! I have about 4 hours worth of data from M51. I captured my subframes with my 8" Orion Newtonian Astrograph and my Nikon D3200. About two hours of data are from 30 second exposures (some at ISO800 and others at ISO100). The rest are 4 minute exposures at ISO800 (these were captured after I bought my Orion Starshoot SSAG). In order for DSS to align these frames, I need to have different star detection thresholds for the 30 second subs and the 4minute subs. I tried doing this by using batch Stacking, but it still uses the same detection threshold for all the file lists (or so I think, since at 20% it stacks almost all the 4 minutes, but at 6-7% it only stacks one of the 30 second frames). And fyi, when stacking only the 30 second frames, there is no problem making an image. Stacking only the 4 minute subs also shows no problems. Let me know any ways you can think of to resolve this. I appreciate it!
  7. hey, sorry I had some internet troubles! Should be posted now:)
  8. Hi again! I finished what was for me the most difficult image so far - M81 and M82. I made this with 75X 4 minute exposures at ISO 800. I shot it from my site in Berkeley, so I had to deal with heavy light pollution that made catching the spiral arms the biggest challenge I've faced with imaging yet. Overall, I am pretty happy wit this image. I'm not sure if my camera (a nikon D3200) can do better given my conditions and setup (8" Orion Newtonian Astrograph, Orion SSAG, and an Orion Atlas mount). If you can think of any ways to improve let me know! Enjoy!

  10. Thanks so much for doing this! I never would have noticed on my own! I took the second image in the gif on July 26, 2016. Let me know if you can identify it!
  11. Cool! I think I see what you're talking about in the frame in which Neptune is farther to the bottom left. But I'm not sure if I can find it in the second frame. Do you think you could circle the potential moon(s) in both frames please? Maybe in a screenshot? That's such a great observation, and I'd love to look into it more!!!!! I really hope you can show me:)
  12. Hi! I just remembered I had made a short gif of Neptune this summer over two nights. My fast reflector has a huge field of view, so you can't really make out any detail on the planet's surface. But you can still definitely make it out, and see that Neptune did indeed wander over the time of a few nights - a planet indeed! Enjoy, and let me know what you think!
  13. Hi! I've been imaging from my new spot at UC Berkeley. The astronomy department gave me keys to the roof for astro imaging purposes, and even though it's a heavily light-polluted spot, I'm very happy with the results! Over the past week, I've been able to get some decent (by my newbie standards) shots of the Horsehead & flame nebula, as well as the Leo Triplet. The Horsehead nebula is made with 4 minute subframes at ISO 800, for about 3 hours and 8 minutes of total exposure time. The Leo Triplet is also made of 4 minute subframes at ISO 800, for a total of 2 hours and 46 minutes. I've included some closeups of the individual galaxies from the triplet as well. I did some serious layer masks on these guys, but I'm not sure if that counts as cheating!! :'D Please let me know what ways you think of for me to improve, and what you think I should keep doing! I took these with a Nikon D3200, an 8" Orion Newtonian Astrograph on Orion Atlas mount. I use an Orion SSAG on a 50mm guide scope. I'm using a 2" Astronomik CLS filter as well. Thanks, and enjoy!!!

  14. I'm planning on stacking Ha frames alongside the images I took with an Astronomik CLS filter, and possibly with my Baader Oiii filter. Also great work PeterPCP. Thanks a lot!
  15. Hi everyone! And thanks again for the responses - VERY helpful! So here's the deal: I tinkered with he register settings, trying all the way from 2% to 80%, and I was getting nowhere. And the other parameters have never failed me before, and so I kept those how they were ("changing one variable at a time," as they say in my lab classes). So I went through all of my subframes ne by one, and about half of them had streaked stars! I would normally suspect I messed up the auto guiding, but I think that the problem lies with my roof. The roof of my apartment building is a bit rickety, and I think that my presence up there alongside the telescope (the whole time breathing, shifting in my chair, etc) caused vibrations that shook the scope. In all honesty, about half of the frames were not acceptable for use in a final image, so I ended up putting in only the frames in which the stars showed up as perfect circles. I tried stacking these with my stacking settings were at 46%, and it did the trick! I've attached the image below. It's waaaaay lower quality than the rest of my work, but at least it stacked this time! This is a jpeg of the original DSS output. I tried processing it a bit, but there is a really bad moonlight gradient, and not too much detail. I included this version in case it is more useful as a diagnostic tool. I think the main sources problems in my initial data were the full moon and the shaky roof. My plan to combat this on the next imaging run (this weekend if the weather holds) is to avoid shooting in moonlight (which should be a bit easier this weekend) and to set up at a better site. Luckily, my astronomy department gave me approval to set up my AP setup on their roof and image from there - a far more stable platform that even has a permanent 17" telescope dome (hope to take that out for a spin in the coming months!!!). Anyway, do you have any tips on how to get an improved version of this image besides more data and the improved site? Thanks so much, you guys are heroes!!!
