Some Ursa major (or close to) galaxies

Super stuff there John. Great Tracking too. Those images look great.

Tracking accuracy seems good John.
My suggestion would be to take more images of the same exposure.
Go for 30 x 2 mins next time.
This will help cancel out the noise and will allow you to process more detail out of the image.
I presume you save the files from the camera in a FITS format?
WHat software do you use for combining the images?

Michael.

Thanks Michael

I am saving the files from the camera in RAW format, stacking with deep sky stacker and saving in TIFF format. I then use a very basic program that came with the Canon camera to process it a bit further. I don't have photoshop or any programs like that.
30 x 2 minutes sounds good but I gaurantee that if I do that someone will recommend using 50 x 2 min etc...etc...and so on exponentially:woohoo: If only we had that much clear skies

Signal to noise improvement is a bit like approaching the speed of light...you just can't get there ?? : blink:
