Supernova in M101

Recommended Posts

Thanks Terry for flagging this, I saw a few images already posted up - looks rather bright.

I had packed all my imaging kit away for its summer hibernation, but as I had completed a M101 image prior to packing everything away - I am thinking to grab a few hours and see if I can merge my before supernova and after supernova images (assuming I can get enough integrtion time and reasonable quality with no astro dark at the moment)

Anyway - long way of saying I've woken my astro gear out of hibernation and setup in obsy this afternoon with hope that next few nights are predicted clear and I can capture a supernova,

I got the bulletin from the AAVSO about this supernova a few days ago. Photometry is my thing rather than imaging. The increase in brightness of this star is astonishing. From magnitude 21 to about 11  in just a few days. It would be great to see comparison images of M101.


I was out last night doing time sequences of the star.

all going well I will have another data set tonight - making it three nights in a row imaging M101 with SN 2023ixf, I’m going to integrate everything over weekend and generate an image , but if you need access to subs for analysis I’m happy to share and I happen to have imaged M101 without the supernova back in - April for comparison- drop me a PM and we can work out what data might be helpful and we can set up a cloud share.
