  1. Thanks for your comments. Nitpicking and criticism is totally fine with me. Your feebdack is highly appreciated.
  2. I don't know what happened, suddenly we had 2 or 3 consecutive days with good seeing here in Germany last week. Took my chances and went out with the C11 I aquired a bit more than a year ago. Here are the results, and I must say I am quite happy with them. I know that many guys here can do more, but I still consider myself as a beginner and will be glad if I could continue learning from you.

  3. Hi there, I am a beginner in astrophotography and want to try imaging Venus with my one year old C11. This is my second attempt on Venus with the C11, and the first in UV. Seeing was very bad, unfortunately. Here you go, two captures (~ 9000 frames each, 11% stacked) while the seeing was about to move from "very bad" to "horrible": I also captured Venus through an IR pass filter and tried creating a false-color image composition. However, the result had nothing to do with the UV and IR captures, so I decided to capture more data before trying again. Since there are many experienced people here, I was hoping for some advise regarding capturing Venus. For me, it's hard to tell if the darker areas in the captures above are actually cloud or atmospheric details or just bad quality areas in my frames. What do you think? I tried imaging Venus in UV through my 2x Barlow, but it seems that the Barlow blocks almost all UV light. What 2x Barlow do you guys recommend for UV imaging? Could it be that the Schmidt corrector plate also blocks some of the UV light? Does it make sense to do UV imaging with a C11? Or should I go with my 8 inch Newton and a TeleVue 5x Barlow? I used an ASI ZWO 290 MMC cam. I guess it makes sense to move to a monochrome cam when using IR or UV pass filters? Do you have any good tutorials on how to create a composition of IR and UV images from Venus? I looked up some tutorials, but it would be great to get recommendations here. Any help is highly appreciated.
  4. @RolandKol Thanks!! Hehe, the setup is indeed long: Cam -> ADC -> Barlow -> scope; it looks hilarious I use ASI ZWO 290 MMC (Color, cooled) and it works very well with the ADC (I use the one from Omegon, the Mark II from ASI ZWO was out of stock, but both should be fine). Getting in focus with the ADC is indeed a challenge when not using a barlow, but when using one, there should be plenty of room for getting in focus. But.. that's only for my Newton 8'' 200 PDS, don't know about your scope, though. Your moon picture are almost perfect without an ADC, I am wondering how your Jupiter looks like when you use an ADC anyways....
  5. Thank you so much! I can relate, Saturn and Mars are hiding behind a hill, so I usually have to wait a while until I can start looking at them. Last night I managed to configure my ADC correctly, so some new details were visible on Jupiter. And I managed to get my first "sharp" pictures of Saturn!! I almost cried when I saw the results last night, after being outside for 6 hours ? There you go!
  6. @JohnSadlerAstro Thanks a lot! If you like the red spot, I hope that one of the animations below is something for you (see attachment). Do you mind showing us your Jupiter images? I am very curious, and I bet they aren't that bad. Regarding your equipment, I believe that it is good enough. Your barlow should be a premium barlow, but satisfying results can also be achieved with "cheap" barlow lenses (I used a 2,5 barlow on Jupiter during my first imaging sessions weeks ago and the results were clear and sharp). For me, the key to better images were limiting the image sizes and shutter when recording with FireCapture. I managed to otbain > 200 FPS which makes it possible to record 20 000 frames within 90s (90s because of Jupiter's rotation).
  7. Wow, those are awesome pictures of the moon @RolandKol I was out last night and managed to catch Jupiter and Saturn. Thanks to my new ADC, I am getting better, but I am still not happy with the results.
  8. He, good idea using SharpCap's focusing aid! Thanks @RolandKol ! Using RGB Balance is quite easy: Simply click on "Auto balance" (see screenshots). The effect is quite astonishing :-)
  9. @RolandKol Thanks a lot! You might be right regarding the focus. I am still tuning manually until I think the focus is reached (and the Firecapture helper says at least 100%). Great picture! Just wondering: Did you use RGB balance within Registax? The compositions are easy to make: I upload the pictures to Google Photos -> New - Collage
  10. Thanks @RolandKol ! For planetary imaging, I use the ASI ZWO 290 MMC (Color, cooled). I was lucky enough to get my hands on a used model.. maybe I would have chosen another cam if I had bought a new one. Anyway, was out again last night, this time my results are a bit better (3x premium barlow):
  11. Actually, those a good pictures for someone taking the first steps. Mine are a bit worse, but I hope to catch up to you soon
