Galaxy NGC3521 18.15 hours

I actually took closer to 50 hours of this one as part of my new program of imaging doing very long exposures as my normal thing.

2 hard disk failures, a reflection problem that wasn't there last time I used my scope (it took a while to get to the bottom of it) and the usual losses to cloud etc took a toll.

I ended up with 18.15 hours of usable high quality data. Some of the seeing though was sensational and I was amazed at the downloads.

I also started using 15 minute subs after tweaking the PME mount.

This galaxy has a large distorted star halo around it. It appears to be distorted by either another smaller orbiting galaxy or perhaps its merged with another smaller galaxy at some point in the past.

I was pleased to be able to capture the extended halo of stars.

CDK17, Proline 16803, MMOAG, PME:
