Andromeda with the K-1
Lens: Takumar 200mm f3.5 Preset Camera: Pentax K-1 Photo Location: Colorado ISO: 800 Shutter Speed: Above 6s Aperture: F4

Here's my first real go at stacking, with dark frames, light frames and flats.

It didn't turn out right (strange halo effect and weird colors), but I was able to fix it somewhat. The stacking program has HUGE amounts of variables, so I am sure I am not getting the best out of the images.

This is 30 images stacked, each image shot for 30 seconds at 800 ISO. Just shot in my backyard with l bright half moon, so not the best circumstances. It is also HEAVILY cropped, so it isn't as clear as it could be.

Wonderful Astrophotography. I would say, skillfully executed. Thanks for posting.

I am impressed. The dust clouds show up nicely. I am itching to give stacking a go myself but I suppose it is a steep learning curve. I suppose Andromeda is a good start point.

Wow I need to give this a try. You captured another smaller galaxy in the distance as well. What software did you use to do the stacking?

Thanks everyone. I am using Astro Pixel Processor for the stacking, then post processing in Photoshop.


Had another go after some reading.

It turns out I was calibrating my camera sensors wrong. So after calibrating it the right way, I am able to get 50+ seconds with a 300mm lens.

Here is an 8 shot stack taken with 50 second exposures. I am going to have to take a lot more exposures after seeing how good just 8 looks!

Here is the cropped photo.





And here is the uncropped photo so show how much cropping is involved at 300 mm with a full frame camera.
