I was lucky enough to spend Easter in Mauritius and managed to get a night of imaging in despite the tropical night time clouds! As someone who lives in the Northern hemisphere, the Carina nebula has always been a target I've coveted, but during my holiday, I also loved Crux as prominent constellation in the Southern sky. So when I ran into polar alignment issues with my Skyguider Pro, I decided to play it safe and go for a wider field, capturing both those targets rather than focusing purely on Carina as was my original goal.
This was shot from my father in law's rooftop in Bonne Terre, Vacoas, Mauritius and my basic polar alignment meant significant field rotation, but I still got some usable data. Cropped, processed and finally upsampled.
Data was shot at f/2.8 with a 50mm lens, unguided on an unmodified Sony a6500. 174 lights at 30 secs each = 1.4 hours of integration. Bortle 5.
From the colours it looks like these objects sit right on the disc of the Milky Way and I know there is more in the picture I haven't mentioned!
Thanks for looking!
A photo of the Carina Nebula taken using a 8" SCT at F6.3 (1280mm focal length) with a Astro modded Canon 40D, ~59x39 arc-minutes FOV.
During an imaging session of Eta Carina close up, one sub on 9th March had an extra star on it, only lasted for a few minutes at most and vanished. I suspected either a GRB, CR or perhaps a Shock Breakout.
In between the meridian flip of imaging another object, I slewed the scope toward the Carina Nebula to see if the point of light reappeared... if it was a SB than perhaps there was a chance that a supernova would have happened, but no such luck.
The Carina Nebula (NGC 3372) also known as the Grand Nebula, Great Nebula in Carina, or Eta Carinae Nebula, is a large complex area of bright and dark nebulosity in the constellation Carina. The nebula lies at an estimated distance between 6,500 and 10,000 light-years from Earth.
Total exposure time was 1 hour 57 min 30 seconds. Subs captured are 15x30s, 10x60s, 14x150s, 13x300s at ISO800 on 27th March 2018.
This is the photo of the Carina Nebula taken using a 8" SCT at F6.3 (1280mm focal length) with a Astro modded Canon 40D, ~59x39 arc-minutes FOV, to try and verify whether I spotted a supernova.
During a imaging session of a closeup of Eta Carina which I started at the beginning of March, one SII sub (9th March) had an extra star on it, only lasted for a few minutes at most and vanished.
After eliminating noise and/or a reflection, I suspected it to be either a GRB, CR or perhaps a Shock Breakout.
In between the meridian flip of imaging another object, I slewed the scope toward the Carina Nebula to see is the point of light reappeared... if it was a SB than perhaps there was a chance that a supernova would have happened by now, but no such luck. I should get a T-Shirt made that says "I was looking for a Supernova, but got this lousy photo instead." :-D
This is a quickie image that I took to check for changes in the location where I thought I caught a supernova (or some flare) on 9th march that I thought would be of interest to someone.
This was imaged in between a meridian flip of imaging another Nebula near the Carina.
This is through a focal reducer and imaged at f6.3, 1280mm FL using my 8" SCT.
Consists of a dozen 300s and another dozen of 150s ISO800 subs.
I'm currently in the process of imaging "the pencil" Nebula, but seeing that it's not clearing my obsy roof until past midnight, I didn't want to waste half of clear nights (since they're rare) so before continuing on the pencil, I did a random frame up on eta Carina and used a random star that popped up in the OAG FOV.
I ended up doing this over a couple of nights but last night I had a bout of cloud cover for about an hour... and the Nebula drifted.
PHD moved the mount looking for a guide star locking in on some noise and attempting to move it to the guide position. What resulted was, when the clouds passed and a guide star popped up, PHD grabbed it and continued imaging, except that the framing moved 2/3 of the way down... and I ended up with subs for the bottom part of eta Carina.
I had plenty of subs from the previous night of the top part, so I created this mosaic... Talk about a accidental 2 pane mosaic!!!
Accidently created my first DSO mosaic.
This consists of 24 x 300s (top half) and 18 x 300s (bottom half) ISO400 using the modded 40D at the 8SE native focal length of 2032mm.
