Longer Stacks of Galaxies in Leo

I went out again tonight.

First I replaced the sand paper tape around the axis (took me a while removing the old one). I replaced the battery in my flash light. The collimation laser might need a new battery also - but I did not have one on hand. I cleaned the mirror with lens spray and a lens cloth - it might have been a mistake, it looked scratched when I collimated. By the time I was setup it was probably 9:30pm. I wrapped up a bit before 11:30pm.

I followed the same strategy as last time.
I captured ~10' worth of images for a handful of targets: this time galaxies in Leo. I used the FR but no filter.
