First Mars with the ASI290MM

[Stefan Buda]

Probably second best RGB from last night. One minute per channel.
Given the 45 degrees altitude, I don't think I can do much better than this, although I can try better processing.

Great shot Stefan. :thumbsup::thumbsup::thumbsup:
Similar shapes to what I got. Seeing wasn't the best. Processing is hard yakka.

[Camelopardalis]

Nicely detailed, and tastefully processes, well done :thumbsup:

looking good there Stefan - yes the altitude was a pain. looks nice and not overpushed

[cometcatcher]

Some nice fine detail coming through. Which scope was this through?

[Stefan Buda]

Thanks for the comments. I always try to match the visual appearance, with the processing. That means one needs to stare at the image for a while to see the subtle details, just like at the eyepiece.



The old DIY 16" Dall-Kirkham, at prime focus. It is in bad need for a primary recoat.

That's a brilliant pic. DIY eh? You're the best!!

[Stefan Buda]

Thanks, but have a look at the reprocessed version.

[Stefan Buda]

Added a version with more contrast that should compensate for the foggy primary.

Outstanding result Stefan, well done! :thumbsup:

[Atmos]

Very nice Stefan :thumbsup:
Are you finding the 290 a big improvement over the 120?

[sharpiel]

It's amazing. The stuff you build delivers such outstanding results. I hope you never become a Marvel or DC Supervillain or the world will be doomed. :)

Thanks Andy,
This was a 3 minute capture and I'm still sitting on a 9 minute RGB set that I will process when I'll have more time.



Thanks Colin,
Definitely yes. This is my 5th generation planetary cam. First one was a DIY one, back in the late 90s.


:lol: Do not worry. Lately I've been thinking that I should replace the 16" optics in the old D-K with 14". I think a 14" better suits the seeing here. Also when I did the figuring of the 16", I did not use an interferometer, because I did not have one. I should be able to make a better primary now, and also reduce the thermal mass in the mirror box.

Those images are great Stefan. Very sharp and detailed. Among the best I have seen so far. Thank you for sharing these. Hmmm so many great images here on IIS.

[Retrograde]

Awesome work Stefan. :thumbsup:

[Dennis]

Lovely images, well done.:thumbsup:

Finally finished processing the best RGB set from the night. This spans about 10 minutes and it was derotated with WinJupos.

[Atmos]

Lots of great detail there Stefan!

[Saturnine]

The newly processed image is a beauty, very smooth and detailed. Possibly the best I've seen this season.
