Last night's efforts


Recommended Posts

Spent a bit of time in my back garden last night with my DSLR and 300mm lens attached to my CG5 mount.

Double Cluster in Perseus.  26x 30 second exposures at ISO1600.  24x darks.


M33 Triangulum Galaxy.  50x 30 second exposures at ISO1600.  24x darks.


M31 Andromeda Galaxy.  62x 30 second exposures at ISO1600.  24x darks.


All stacked using Deep Sky Stacker and processed using a combination of the Luminance tool in DSS and Photoshop to adjust the levels and curves and remove gradients.

Not perfect, but I'm still learning.  This was only my second attempt with the camera attached to the mount and I obviously hadn't aligned it quite as well as I could have as exposures longer than the 30 seconds were leading to some star trails.  Not sure what I did wrong as when I first tried it last week, I was able to take 2 minute exposures before the star trails became evident...
