This is a close up of IC 2944, also known as the Running Chicken Nebula or the λ Centauri Nebula, with the Bok Globules visible in the upper third of the frame. IC2944 is an open cluster with an associated emission nebula found in the constellation Centaurus, near the star λ Centauri. This image was exposed using a Cooled as astro modded DSLR through a Celestron 8" SCT at it's native 2032mm (f10) focal length. The total exposure time was 60.5 hours, through HAlpha, SII, OIII and UV/IR excluded natural colour.
I hope everyone is keeping safe in this weird time we have found our selves.... I guess social isolation is something that us astronomy geeks are used to, goes with the territory.
I have been imaging a little bit between the full moon and cloudy nights... I have acquired some data of three objects since January that I'm only starting to process very slowly as time permits. It is easier start to to collect photons than sit down to process the data.
The attached is a close up of IC2944 around the Bok Globules area, AKA The Running Chicken Nebula... imaged in SHO hubble palette.
This is the latest image exposed...This nebula is a deep southern sky object, located about half way between the Southern Cross and The Carina Nebula.
Since I have a permanent setup in a small hut, I found myself starting the exposures during multiple night as I arrived home from work, tired and only wanted to go to sleep. If I didn't have the gear already setup there is no way I could (or would have the will to) spend so many nights on exposing subs, but as in my current situation, it is easy to just start the exposures and go to sleep... deleting the failed subs the following morning/day, and continuing during the following clear night for as long as I wanted....
The exposure time of this was about 60 hours in total, 55 subs each of 900 second HAlpha, 1200 second OIII and 1800 second SII subs, at ISO 1600 using my cooled Canon 40D astromodded DSLR. Overkill.. maybe... but can't hurt.
The tracking was on a CGEM mount, through a C8 SCT at native F10 (2032mm focal length) autoguided on PHD2 using a OAG.
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
