The Pinwheel Galaxy M101, about 21 million light years away. On the left edge above center is a companion dwarf galaxy, NGC 5477. #astrophotography #seestar #m101 #ngc5477

The Pinwheel Galaxy (M101) is a face-on spiral galaxy located 21 million ly away in Ursa Major.

Beyond its striking appearance, M101 is home to over 1,200 catalogued star-forming regions, an ultra-luminous X-ray binary system and around 150 globular clusters.

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 https://fosstodon.org/@AkaSci/110402301121258093 for more info on SN2023ixf.

M101 Pinwheel Galaxy and the newly discovered supernova SN2023ixf from the Bootleg Astronomy 2023 Spring Star Party. Comparing with my 2022 photo, you can see the supernova just wasn't there yet. Who says reshooting targets isn't worth it? More image details on Telescopius or Astrobin. Thanks for looking and Clear Skies!

Clear skies at last, after 3 months of clouds… This is the pinwheel galaxy (M101) with the supernova SN2023ixf (marked with small red lines) that has appeared on May 19. This picture was taken during 2 consecutive nights (May 27 and 28) with a small refractor (400mm focal length). Total integration time was 4h50. Image processed with Pixinsight.

Apologies for the crappy image quality - made this on the Dwarf.ii telescope a couple of nights ago - but one of them dots is a supernova :)

Learning by doing/trying, I gave imaging M101 and its supernova another try. Still disappointing -- a very challenging target anyway but given our poor seeing here, well, disappointing results. Add to that the learning curve I'm on using an astronomy camera instead of a DSLR and... I turned to the 10-day-old, waxing Gibbous Moon last night and got some experience and passable results. Here's a pair of pictures -- the same image but the second is labeled. #M101 #Moon #astronomy #astrophotography

Well, last night's efforts at shooting Messier 101 and its latest supernova were less than optimal. I was unable to track accurately enough to collect enough photons in each frame for a successful image. I'll probably be working next on getting autoguiding up and running. While I was out I made a quick grab of M57 -- the Ring Nebula -- and it's pretty; helped soothe me today when the M101 effort proved fruitless! Bortle 6/7 sky. #m101 #m57 #supernova #astrophotography

Here's a quick blink of the supernova between Mar and May 2023. Same gear, similar integration.

Watch the very short video I made about the supernova, my gear, and my two images here: https://www.youtube.com/watch?v=1MrPU5dVDQo

Shooting for M101 and its supernova tonight. We finally have clear enough skies and temperatures that are me-tolerable! Starting with the Vixen Cassegrain in place of the C11 ‘cause the Vixen is proven and I’ve got *one night* to do this. #M101 #astronomy #Astrophotograpy #supernova #Vixen #C11

I finally managed to process my own image of the #SN2023ixf supernova in #M101.
Crazy to think this event actually happend some 21 million years ago, but we can still observe it changing brightness in mere days.

#supernova #astrophotography #astrodon #space

Finally had time to image and process #SN2023ixf. This is my second Supernova capture this year!

These are both around 90 min integrations. Will make a quick video about this but won't be able to capture further images sadly.

A better picture, can you find the supernova? So happy we got a few hours on the light curve, the galaxy will really pop once reductions are finished too! #m101 #whirlpoolgalaxy #yorkobservatory #supernova #astronomy #Astrodon

AAVSO finder chart for the field of #supernova #2023ixf in #M101, plotted with a 1º field of view and a limiting magnitude of 14. Comparison star magnitudes are shown without decimal points, so, e.g., "119" = magnitude +11.9.

This picture represents one of the happiest photos I've taken. Last week I had a mishap and my rig had a run-in with an unexpected sprinkler that ran overnight. Electronics are not a fan of water. It all survived thankfully (minus a LiFePo4 battery pack) and this is data from 4/29. M101 - Pinwheel galaxy. #astrophotography #m101 #pinwheelgalaxy #zwo #am5 #asi294mm

This is Messier 101, also known as the Pinwheel Galaxy. M101 is 21 million light years away from earth. This represents 6 hours of RGB data taken over two nights in Hemet, CA. #astrophotography #m101 #pinwheelgalaxy #zwo #astro-tech #asi294mm #am5
