Jupiter 13/2, 14/2 first attempts

[kkara4 (Krishan)]

Attached are my first attempts at photographing jupiter - on 13/2 i spent an hour or so collimating as best as I could with the seeing, couldnt get it as spot on as I would have liked.

Canon 5D MK III, Televue 4x powermate, EdgeHD 925.
Backyard EOS to grab 1000 frames - ISO 800, 1/40s
Registax to reject all up about 40% of the frames.
Wavelets in Registax then minor photoshop to adjust exposure and colour.

I suspect resolution of the DSLR is an issue to get proper sampling at f/40 on this scope...clouds stopped me from trying my QHY5L-II and IR-RGB filter set, which ill give a go next i think.

either way im stoked with what i could do, and was awesome to see Io and a shadow transit for the first time

If anyone has any suggestions for improvement please let me know!

Well done Krishan, I can't get anywhere near that good with my DSLR!
Cheers

Thanks Bob! i think seeing and collimation are still my enemy - the seeing also makes it very difficult to get good focus. but live view helps immensely. i found even 1/8 turn on the fine focus knob makes a difference so have to spend time focusing properly.

if clouds are out of thw way tonight might try IR RGB instead, see how that works for me.

I agree. Last night (2/14 PST) seeing was exceptional in California. I pulled out my iphone 5s and took the following hand-held photo of Jupiter and IO moon. Just one unprocessed frame. I took the photo at 500X. I was surprised to have captured IO as a disc. If seeing did not cooperate, I would have ended up with a washed white disc without features at that magnification. Attached photo is little fuzzy because I took it hand-held with an iphone. Jupiter looked superb a the eyepiece with plenty of details.

Awesome for an iphone Jason! thanks for confirming to me that it probably is most likely to be my seeing.

ive yet to experience a night of even good seeing i think...maybe one day

Very nice Jason, hopefully one day I get seeing that is at least better than mediocre!
