NGC4631 & NGC4656 - The Whale Galaxy & The Hockey Stick Galaxy
Fri May 31 2024
Long story short, after months of equipment issues with my C8 telescope, I’ve still been unable to fix the problem and have decided to use my other scope, the little 72mm refractor just so I can do some imaging again. This one won’t win any awards or anything as it’s pretty short on total exposure time and focal length but I’m just happy to be out there under the stars again!
