Mars April 18th

[Space Cowboy]

Wobbly seeing on this night but did improve for one avi taken at 23.45. As trans was excellent I ramped up the shutter speed and got 45,000 frames for this one with 5000 stacked :

10" Dob & QHY5L-II C + 5x powermate@f22 :

Yes Stuart nice work, similar results to me,the colour & detail looks good, theres nothing worse than over processing on mars!

Blimey 45000 frames what frame rates are you pushing, a average stack for me is about the same as you!

[Alan]

Nice detail Stuart, I was out about the same time with seeing fair between the clouds

[Space Cowboy]

Cheers Alan!

Thanks Simon I was running over 150fps but had gain at 80% to achieve this. Bit too much noise showing on this image so done a repro using 1.5x drizzle on a 10000 frame stack and also include a mono IR 742 shot though not overly impressed with this shot. The mono cam is not giving me any extra detail on Mars which surprises me.

Stuart,

On my monitor the image looks a bit too blue Stuart, with a blue fringe on the right. Perhaps dropping the blue a bit and re-aligning in R6 may bring out even more detail.

Cracking shot anyway

Good detail.

Cheers Peter!

Thanks Alan. I always run auto RGB align and that blue fringe on the upper right limb never budges even when using manual align but I've just discovered that "create luminance in RGB" in colour mixer gets rid of it. I'm not sure whether the fringe is something in the Martian atmosphere? Anyhow here is the "de-fringed" image :

That`s a wonderful, detailed shot of Mars, Stuart. Great capture.

Well Stuart, who would have guessed! Better for it though methinks

[Space Cowboy]

Cheers Ralph & Alan!

Thats a really nice image Stuart, best Mars Iv'e seen from you so far.

Regards,

Pete.

[Space Cowboy]

Thanks Pete! Think I will repro my previous shots from 14th & 15th using drizzle as I did this one.
