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'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 250-25^o 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.

Saturday I went out to our astronomy group’s dark site with 18” f/4.2. There we five of us observing and we were able to see SN202oi at about 90x and 190x. Darkness was good, seeing was excellent and transparency was excellent except for clouds that making a mess of imaging on and off. First time I’ve ever observed a supernova in progress. It was quite exciting for all.

I tried getting some more images but due to the clouds was not able to collect a lot of subs. When I have some time I will post process and see how it came out.

SN2020oi is challenging target for short focal length. Only aggressive deconvolution helped me to to distinguish SN from M100 core. Click on image for full resolution.

Let’s hope no one was too close to it.

I felt a rustling in my ear hairs as the gravitational wave passed by but since I lost most of my hearing stationed on a aircraft carrier in the '60s, I didn't hear the tone.

Here's an image I captured 1/31/20.  SN2020oi is definitely fading compared to my earlier image.  Haven't been able to image it in the last week due to weather conditions and the moon.
