C9.25 first light

[Jeff]

My first attempts at Jupiter and Saturn last Sat 14/07 using a C9.25 purchased recently from another IIS member.

Still getting the hang of the manual focusing on the C9.25.
Not sure whether I need to separately focus for each RGB filter. :shrug:

ZWO 290mm Orion RGB filters.
2.5x PowerMate for a FL of 5875.
SharpCap, AutoStakkert, WinJUPOS.
Jupiter 60 sec RGB runs @ 12ms subs and Gain 350.
Saturn 120 sec RGB runs @ 30ms subs and Gain 400.

Tips welcome!

Lovely images, especially the Saturn one. I think F25 is the sweet spot for the 9 1/4.

Grouse results Jeff, Saturn is very 'crisp' :thumbsup:
Did you have any Jet-Stream at the time ?

Sorry cant help with Re: focusing on seperate filters, I havent had a mono cam before, tho, one is in the pipeline, so, I be watching with interest for any further discussion relating this aspect :cool2:
Tho, I would suspect Not with Planetary, as time is of the essences ?
But on the other-hand,,, maybe, if filters are not parfocal, but again I'd assume these day's most would be, atleast reasonably well :question:
Do you notice much difference in the screen view after changing filters ?

Nice result all the same :thumbsup: :thumbsup:

Thanks Paul. I was worried about the FL of almost 6m under average seeing, but encouraged by the results.



Thanks Bob. No Jetstream … seldom bothers us down in Melbourne. But bloody cold (1.3 degrees), and a little bit of fog starting to block stars at lower altitudes. The Orion RGB filters seem close to parfocal, but not quite. Screen/histogram brightness varies per filter … especially for Mars, where the Red transmits heaps more light.

Good luck with your imaging! :thumbsup:
