Jupiter Feb 28th

[U.K.Cowboy (Stuart)]

Still capturing Jupiter as she floats further away. Seeing was reasonable on this night. Couple of images plus a short animation (please excuse the wobble as I've yet to find a reliable way of correcting field rotation).

All done at f26 with Auto Dob and DFK:

Very nice Stuart, the time has come to start looking at Saturn

Cheers mate! Yep I've yet to capture a decent Saturn this year just a very blurry one from Jan.

Just a bit confused as to why my images are only showing links? The images are on screen in post preview but not when posted?

Really nice hi-res detail in there Stuart, the WinJUPOS derot really does work rather well and the extra data makes for a lot better signal to noise ratio.

Cheers

Great amount of detail in this Stuart Id be Stoked with something even close to it, impressive for a 10"dob , ,

Thanks Trevor! Yes de-rotating stacked images certainly produce a smoother image. Provided seeing is consistent you can be much more severe with selecting frames. I think I used 4 images each consisting of 1000 frames from 10,000 so the de-rot image contains 4000 frames. Individually the 1000 stack images were way too noisy as gain was about 85%.
I've yet to have much success with de-rotating avis as it seems a lot of work for little reward.

really nice Stuart - lots of detail.

WINJUPOS should also correct the animation wobble - if you go through the image measurement process for the frames of the animation, they should end up with exactly the same alignment.

have had similar lack of success derotating avis.

Regards ray

Thanks Ray! Even with winjupos aligning each frame I get a tiny wobble which is annoying. For this animation I did a quick alignment in image analyser which admittedly is not a accurate unless a lot of time is spent making adjustments.
