I observed SN2020oi last night from the SE Oklahoma dark site. It was a lot more difficult than expected. Luckily it was a great night for the site and when I got the magnification up to 567x via 3.7 Ethos and Paracorr I was able to directly compare the shape of the core to a close photo of the SN I'd attached to my observing list and catch repeated glimpses of the object in it's place with direct and averted vision.

I'm beginning to think that observing this supernova from the orange-zone Naylor Observatory may be extremely difficult or perhaps impossible.

I was definitely thinking that was my case too until really jacking up the magnification made it possible. SQM-L was 21.44, wind was zero, transparency was maybe the best I've ever seen and stars were completely stable until the dropped to about 250-25o above the horizon. Only when I could clearly see the shape of the galaxy core could I firmly nail the observation by comparing it to the pic.

It was extremely difficult to me.
