A single shot at 40 seconds enhanced in photoshop.

No bad for 40 secs. What ISO? Flats? Darks?

Gives me food for thought. As soon as I can get a clear night and no moon, I might have a stab at the Magellanic Clouds.
Cheers.

reply to cheers

No flats or darks iso 1600 sky,, first quarter moon setting and some light pollution saved as dng. file. The K5 is a great astro camera. and I have used many ccd cameras and cmos cameras.

m31 on with k5

This shot is from 14- 40 second dng photos stacked with deep sky stacker enhanced with photoshop through my stellarvue 102 ed mounted on a celestron cgem mount
No guiding, no flats or darks. again shows the quality of the K5 . I wonder if the K5 11s will be much improved?

If I were to use the IIs for astrophotos, it'd only be with the hot filter replaced. I'll be watching to see if vendors offer the service as this could be something worth saving up to get.

Here's a 1:1 crop of the dust lanes from my Andromeda image. I'm curious if I can pull this detail out of a K5, how much will a K5IIs add. Should be interesting.
This stack is just lights, no darks or bias files.

m33 and K5

M33 (whirlpool neb)12 frames iso 1600 40 to 50 sec. each no flats or darks, no in camera noise reduction saved in.dng. Each raw frame enhanced in photoshop raw first then stacked in deep sky stacker. and final image enhanced in Photoshop. We have had so few good seeing nights that I can't find time to image only one object. This camera in the few frames takes great pictures. I had several other brand cameras and the banding and noise in my photos was impossible to remove. If the K5 11s can improve on the K5 quality that will be a buy.

well according to this link, I was in a "green" area Parks Canada - Elk Island National Park - Beaver Hills Dark Sky Preserve: Leads you into the DARK! however that said, once your eyes have fully adjusted, looking back west towards Edmonton you see the light pollution. Andromeda however was more east, so away from the city which probably helped. Here is what one 3 minute exposure looked like as a reference as I did spend a couple hours adjusting curves and the colour channels in Deepskystacker, and then some fine sharpening and saturation in photoshop. Here is 1 frame of 3 min exposure no adjustments, default camera raw settings as a reference. I also edited this post to include the same raw file with some basic contrast brightness sliders

p.s. ISO 800

Nice, that kind of dark sky is a dream for most people. Any reason you had the camera oriented perpendicular to the galaxy?

no I took a few shorter shots and misjudged its orientation. also it was -5C and wanted to start longer exposures for stacking. Next time I do m31 I'll and orientate it at least corner to corner

my honest option is its closer to yellow rating then green as I couldn't see many stars in horizon.
