NGC2541 - older and somewhat unfinished!

This tiny galaxy, NGC 2541 is an unbarred spiral galaxy located about 40 million light-years away.  Taken on 2x nights in winter of 2019 is quite dim but shows a nice mottled and knotting in high res - https://i.imgur.com/ySLI2H0.png

 

At only 1hr in exposure, I consider this unfinished.  I'm still working on my Sequence Generator Pro routine and mount/guiding issues at this time.  Only recently did I  start to take good enough notes to refine my setup to include drift align, image grading and some base photometry to judge FWHM.  In the past I went for 'good enough' and struggled with pointing models, mount balance and general guiding issues which limited target finding, centering and time on target.  Two nights and only one hour?  Lame!
