After 4 beautifully clear nights where I didn't feel up to observing due to Covid, tonight I'll be having a go at seeing the supernova with my 10-inch push-to Dob. As if M101 isn't difficult enough under my Bortle 5 skies, the Moon is a big fat gibbous phase.
So that this inquiry didn't get lost in the many posts on the main M101 SN thread, I have a question. No doubt that I'll be able to find M101 with my DSC-Nexus-SkySafari rig, but discerning spiral arms will next to impossible. So the question:
- Would the use of a light-pollution rejection filter be of any use? I have two:
- Thousand Oaks Oxygen-III
- DGM Optics NPB Nebula
- No doubt either filter would make M101 itself essentially disappear. But might the supernova benefit from such a filter. I'll give it a try, perhaps just hand holding the filter in front of the eyepiece to see if the view changes with & without filter. Any advice you can offer would be appreciated.
