Supernova 2022hrs in NGC 4647

[ARock]

There have been some reports of this SN here, but maybe not as much as it deserves. So I am posting this in beginners. A supernova of this magnitude is not a very common event. Supernova listing website here.

NGC 4647 is a galaxy right next to Messier 60 in the constellation Virgo and they together form ARP 116 in the catalog of Peculiar galaxies.

The supernova is of Type Ia which is described here

Currently at about Mag 12.5 it is just beyond the reach of my 8" Dob in my light polluted skies. So I thought I would give it a shot taking photos with my trusty ST80 clone (a Meade Adventure 80) on my EQ2/3 mount (EXOS Nano EQ) which is DIY motorized and a DSLR (Canon T3i).

30 lights 25" each (no guiding) at a high ISO on a Canon T3i with a UHC filter, with darks, bias, flats stacked and processed a little in Deep Sky Stacker. I use this setup mainly for Observational Astrophotography to view things using AP that I would not otherwise be able to see.



Comparing the brightness of the Supernova with other known stars in the image it does seem to be in the Mag 12-13 range. If you have somewhat dark skies and 6 or 8 inch scope it is worth a shot trying to see it visually.

You should make this a report an add that to the General Astronomy Subforums / Astronomy Reports and (hopefully) get a VROD.

Nice capture AR! Very close to what I saw visually with my 9.25" Edge the other night.

Yeah, is indeed an easy one. I observed it on 23 April at our dark site in the 17.5 inch and at 94x it was readily apparent between the two galaxies. Visually observing extragalactic SNe is indeed a fun addition to my normal galaxy hunting activities.

Nice image @ARock and I suggest you file a report in the astronomy reports forum if you wish. The process of photographing something in lieu of visual observation to confirm something you can't quite make out because of LP is kind of unique, so please feel free to do so. So far, several reports have mentioned the supernova and have won the VROD including Milan's, Alan's and Andrey's. (milanpicard, KT4HX, bigzmey)...

Thanks Michael, but my intention was to spread the news of the SN to a wider audience. I learnt about it myself from Milan's post.
When I first started, I would see the Supernovae news, and they would be fainter than what my scopes could see, and to me it was in the "very cool, but outside my reach" category. Then I found out that a $100 scope on a $100 mount/tripod and a family DSLR can see these with a little bit of DIY electronics work, much of which has gotten a lot easier these days. Which to me is amazing !!!

And it is the sort of gear that a lot of beginners have or can acquire.

The subforums are not totally mutually exclusive. You can make a posting to the astronomy reports too.

A couple more images there, too.
