M81 & M82


I have set the scope up and all is working well, One piece however was sent incorrectly, a critical piece to the optical train, Sky-Watcher manufacture a dedicated field flattener for the ED100. Unfortunately the one sent was for the Equinox 100 refractor. 





5 Hours total integration time in 3 minute sub frames calibrated and integrated in Deep SkyStacker. A very smooth result showing incredible detail in Ha from the cigar starburst galaxy. Estimated to be 100 times more luminous than our own Milky Way. 

It's incredible amount of star birth is though to have started with interaction with M81 in the distant past.

Who remembers the type1a supernova observed in 2014. I was lucky enough to capture it. I believe also it was the closest type 1a recorder in the last 40 years.

A duo of galaxies & a supernova

Still shining bright supernova 2014j looks amazing.

Weather forecast for the next week or so pretty shocking again. I would love to capture it 1 more time as it fades into the background. I am very happy with the depth of detail captured.

Supernova 2014J

Sometimes the luck just holds. Well this time anyway. If you wander back through my blog or find my post on M95 april 2012. The avid nova watchers will remember the eruption in M95 sn2012aw. This happened just as I started at work a set of nights. We only do 2 sets a year and could not believe my misfortune in having to work when the skies were clear. Now go back a little futher to sept 2011 and sn 2011fe in M101. We were about to move and I had dismantled the observatory in preparation.

But not this time fellow bloggers. I had imaged m82 back in Oct testing out my new kit (left pic) and the wow amazing sn 2014J captured just last night 1 day after it's discovery. I am sure at this moment they are searching through Hubble archives to find the progenitor. We know already it is a type 1a and a few theories exist as to the fate of this white dwarf star.

Anyway here is my pic.

I am trying to do a blink comparison aswell. I will post it if I manage it. Any advice would be appreciated.
