Inspired by Lukas offering, I had a go last night at the same subject, Sagittarius.
28 x 10sec images stacked and processed in DeepSkyStacker.
The camera was at ISO 800, which may explain the grain.:whistle:
Some quality was lost when I converted it from a .tif to a jpeg.
Any advice is welcome.

It was taken with my little Canon Powershot camera.
Trying to test it's limits.
LOL I never thought that it was capable of this though.
Hi Jeanette, that has turned out really nice. Everything is nice and sharp and there is some nice detail appearing as well.
I think you have done very well.
That's very cool for Powershot pic.
That's got me thinking about doing the same with my digicam:)
Thanks for the inspiration.

Well done Jeanette there's quite a bit of detail in there with such short exposure :thumbsup:

Well done JJJ!
Excellent.
Wider angle also allows Jupiter in top left corner to be visible.

This is the new and improved version, minus the aircraft trail.
I played around with saturation etc and managed to draw out a bit of colour.

Shove it in the scope Jeanette! I wanna see how they work thru a scope, not a camera lens. Especially the results from basic amatuers like us. :thumbsup:

Very Sorry Jeanette. I did miss that thread. :sadeyes:
Looks like the G-star picked up the light from the Galaxies really good. What exposure time did you use on those images?

Sense up was set at 48x to avoid star trails.
Not sure exactly how long that means as per exposure. Still alot to learn.
I'm hoping to beg a loan of someones tracking scope at Astrofest, and see how it performs with 128x intergration.

48x? Wierd exposure rating.
Thanks.
Looks promising for when you get to mount it with tracking.

Sorry Ken,
My brain having a major meltdown tonight, and refuses to work. I'll explain it another time.
Or you can to go to myastroshop, and download the manual, read it, then you can explain it to me in simple words of 5 letters or less. LOL
Cheers

Great work there JJ ... I have been doing a bit of short exposure stacks and think it offers graet opportunity for many cameras and places less demands on mount and tracking (somewhat) ...
As to what to do.. just keep doing what you are doing.. try more subs (until the computer says no more) , higher iso (its a trade off but I like more light even if its grainy) and a dark frame subtract... dont come in until the battery is flat or the card is full.. when card emptied and battery recharged go out again and take more...
You should frame your photo I reckon as it is a shot to be proud of.
