The supernova SN 2020jfo discovered in M61 this month.
Photo by Susy Ghia, I processed the frames with IRIS, removed background gradient with Straton than applied photometry and astrometry data using APT and Astrometrica.

The raw images have been shot by Susy Ghia with ASTRA remote telescope, a 90cm f/4.5 reflector with camera SBIG ST-8300M.
The processed image is the composition of 2 frames with exposition of 900 seconds per frame. I used IRIS for registration and stacking, then I used Lightroom CC to stretch the levels and make it more pleasant to look at. I did data reduction using Astrometrica and APT to extract a source list, then I analyzed the luminance frame using TOPCAT and Aladin.

Photo by Susy Ghia with ASTRA Remote Telescope #4 with SBIG ST-8300 CCD.
The photo has been processed with IRIS for registration and stacking than edited with Lightroom CC to make it a little prettier.

This is the result of four images for a total exposure of 35 minutes, I used IRIS for registering and stacking the images, also I applied the Asinh filter to stretch the image to increase the details, than with Lightroom CC I increased the sharpness and reduced the noise a little bit to make it pretty.

The telescope used is a Newton 800mm f/5.
The final photo is the combination of three images in Luminance for a total exposure of 180 seconds, combined with RGB channels. Three images have been used per channel for a total exposure of 180 seconds.
Five images shot by Susy Ghia using ASTRA remote telescope #2 on March 17, 2020. The telescope is a Newton 800mm f/5, and the images have been registered and stacked with Astrometrica with final edit in Lightroom CC.
