  1. Hi everyone! 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!
  2. The Carina nebula is coming up again in the evenings. Since it is one of my favorite objects, it's hard to resist to take another few shots each year. The total exposure time is 43 x 5min ISO 1600. Clear skies! HJ
  3. Greeting Astrolings, 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. Clear skies. MG
  4. I've only just got in to DSO photography recently with this being my second attempt at the Carina neb on the 24th March. I didn't need to do much with this at all in the final stacked image apart from some level adjustment and slight colour correction. I'm very pleased with this even with it's faults. Taken with the Sony a5000 and C8i SCT. 4 x 15 seconds, 9 x 8 seconds, ISO 6400. Each of the 13 light frames has a dark frame added from the camera. Aligned and stacked in DeepSkyStacker, final edit in PaintDotNet. I wasn't sure on the colour so I just guestimated. I did a quick search for images online in mid editing but the results shown were all using filters of some sort or another.
  5. 14-15 May 2015Equpiment: NexStar 8SE On the night of 14/15 May as I continued to image Lamda Centauri nebula through the Sulfur single Ion filter through my refractor, I had to keep an eye out for passing clouds.. there were moments when thick clouds moved 15 or so minutes at a time over the patch of sky I was imaging, so I had to be near it to stop the exposure as the clouds rolled in then start it as they went away….Autoguiding of the running chicken nebula was done by OAG and Celestron NexGuide. So I thought, one thing I haven’t done in way too long was do some nice old fashioned eyepiece observing…. I set up the SCT on the Alt-Az mount I’ll tell you I had some awesome views… AWESOME…. First I looked at Saturn…. It was bright and massive at 406X magnified… clearly visible was the Cassini division in the rings, the cloud belts and ring shadow on the globe and 6 of its moons around it…. then after about 30 or 40 minutes of absorbing that view I moved onto the Omega Centauri… first with the low power 50X magnified… the globular cluster was clear, and a clear fuzzball of stars in the eyepiece circle…. Then I tried the TV11mm Nagler I recently received. The view in high power… what I saw has to be seen to be believed, at 185X not only was the globular massive and the individual stars were resolvable in the CORE!!!! The Core!!! But because the eyepiece is wide view the circle was not visible, it was almost out of the peripheral, so it was like looking into space through a window…. Awesome…. Then I went toward the Jewel Box near the southern cross… at low power the distinct “V” shape of the Jewel box was obvious and the different colors of the stars were visible. But with the high power eyepiece not only were the different colors of the stars visible and glistening but there were so many stars in the view that the “V” shape was almost lost, why it’s called the “Jewel Box” was plainly visible. Next target was the Carina nebul. Here I had to use the ultra high contrast filter to dim out the stars that overwhelm the nebula and I bs you not, with the filter there were actual whisps, folds and structures are visible within the nebula… stuff normally expected to need to be long exposed to see, but were visible through the eyepiece! Before those four I just described I looked at the Lagoon Nebula, the Trifid nebula and the butterfly nebula but those were too low into and toward lights from CBD so the details were washed out, I still saw the “lagoon” in the lagoon nebula but not as defined as it would be at a dark location or position in the sky. The Trifid and the butterfly were just a barely visible smudge. The butterfly had the shape of it visible but only barely. I remember when I took the scope to the mountains and looked at the Trifid nebula from there, the shape of the Trifid was clearly visible as well as the breaks in the “flower” part, tonight was not even close. I’ll tell you... it doesn’t seem like a lot of objects were looked at but more than 3 hours went by like nothing…. I didn’t feel that my bones have frozen through until I realized what time it was and that the object I was imaging moved behind the trees and buildings in the distance. In the last few years I mostly did astrophotography but after tonight I think I need to do more traveling to dark sites and do lot more observing. MG
  6. Hello all, 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. clear skies, MG
  7. Hi All, 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 Clear Skies. MG

    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.
