Similar Jupiter GRS early Saturday 26th

[astronobob]

Hi all Astro'liano's ,,,

I thought it was safe enough to place a scope 'being the Meade 12 acf' on the Cosmo Caboose Pier at Galaxy Station now Im done with cutting 'crete and pavers for underground cabling :thumbsup:

Was exciting to just throw the dslr into it and have a peek at Juup 'live vid mode'
The atmosphere was rather steady, tho transparency being murky cut down on sharpness !
Juupter 2 prog showing some Moon and shadow transits through this time - tho not seen in this Image, , either processing, conditions or timing may be the cause, it was great to have the GRS captured at the disc's center longitude area. Some nice Festoons on display & happy to resolve the odd white storm with in other belt zones

12"Meade with 4x Powermate,,, hand focus :D,,, Dslr in 3x crop video mode @ approx 24FPS for approx 1min 13 sec producing near 1750 frames.
50% stack in Registax 6, wavelengths applied and further PS levels, noise, sharpen ect..
Final image shown has been sized reduced by 50% to hide some horrors, not a classy hi-res image, but this duck is happy with it ..

Hope it worth a Squizz,

Ps, them Zwo asi cool cams look very attractive :question:

nice one Bob, i tried to have a crack the old dslr the other day too, nowhere near as good as this though, also umming and ahhing on a ZWO (even the non cooled versions) - getting it before Mars opposition would probably be a good idea.

Thanx Russell ,,

Non cooled sounds good - I'll be trying the qhy5 next - when better set-up with the lappy & a motor focus of sorts wouldnt go astray, Lol
Oh and sky conditions are rare this way ,,, all in this hobby's pastime :shrug: :cool3:

Hi Bob
Thanks for your comments on my post.
Re focusing, I still use hand focusing with a fine focuser (with a Bahtinov mask) - no motor:lol:. Using F25 I find that focusing is so affected by seeing that the extra few mm accuracy gained with the motor doesn't really make a difference. Just get those bahtinov spikes nicely aligned :thumbsup:
Cheers Domenic

Using a bahtinov Mask with hand-focusing for greater sharpness wouldn't surprise me Domenic, , but might be un-able to do with Jupiter when it takes up over half the camera's chip -

Tho, might be possible on one of the moons if bright enough ?
Worth a shot eh ?
How do you do with jupiter :question:

:cool2:

Hi Bob,
I focus and collimate on a near by bright star, not the planet. I'm using Denebona (below Jupiter) at the minute for Jupiter. A flip mirror helps me find Jupiter after the goto, as it can be quite tricky with a Barlow. The ASI120MC has a large FOV, which I then crop down to size to fit.

Interesting Domenic, seems to work very well indeed :thumbsup:

Must try this, easy enough, thats for sure, good stuff :cool2:

Nice one Bob. Using one of the moons to focus is definitely possible, that's what I do :D

[astronobob]

Agree Dunk, If/When they are in the field i watch them for focus, never occurred to me to go aside and find another when not there :rolleyes:

Ill sure keep it in mind tho - now :D

:thanx:
