#M101

First serious effort with the Seestar S50. 229 minutes of data in 19.72 SQM skies. Even caught 14th magnitude background galaxy NGC 5477. No post processing by me, it's all the Seestar. #astronony #astrophotography #seestar #M101

First try with a new camera, still learning on how to set the different parameters while shooting. Repeating M101 since was the last target with the DSLR camera.

Después de muchos días para las capturas y muchos días de procesado.. por fin parezco convencido con la galaxia #M101 (Pinwheel Galaxy)

Took ~2.5 hours of grayscale exposure on the Pinwheel Galaxy (Messier 101) as a test dataset as I evaluate PixInsight. Might try for some color tonight if the weather permits. Second image highlights the location of the lingering supernova.

Here is some data on the change in brightness of a few past supernovae.

Luminosity of a Type II SN rises for 1-3 weeks and then declines over months.
Type II-L SNe have a steady decline rate, while Type II-P supernova exhibit an intermediate plateau period with a reduced decline rate.
The average decay rate of 0.008 mag per day is much lower than that of Type Ia SNe.

18 days after it exploded on May 19, supernova SN2023ixf in the Pinwheel Galaxy M101 seems to be dimming a bit, as all Type II SNe do, gradually over a period of several months.

Note that an increase in magnitude by 1 implies a decrease in luminosity by a factor of 2.512.
Pre-explosion mag was ~24.
See this thread fosstodon.org/@AkaSci/11040230 for more info on SN2023ixf.
