Orion’s Belt Mosaic. Upper frame is 50×60 sec @ ISO 3200, plus 40×60 @ ISO 6400. The lower frame is data from 2007, 31×180 sec ISO 1600 and some 2013 data that includes 40×180 sec ISO 1600 sub-images. Finally, there are 3×180 sec @ ISO 800 sub-images that were taken on Nov 2, 2014. Scope and camera used were a TV-85 at F/5.6, IDAS-LPS filter and a Modified Canon T3.
Here’s one that’s in progress. I shot this area over two nights. I have very little of the Horse Head region from these sessions, but another 40 subs of the belt stars upper frame area. I should be able to put something together with other data from older sessions and get a somewhat complete mosaic image. (Update: Yes, I was able to add some old data and smooth it out.)
M45, The Pleiades. 40×120 sec @ ISO 3200, TV-85 at F/5.6, IDAS-LPS, Modified Canon T3.
I had time to kill while waiting for Orion to get into position, so I shot 40 x 2 minute sub-images of the Pleiades at ISO 3200. I did not spend much time in post processing this, but it came out half-decent regardless.
The Double Cluster on Nov 1, 2014. 40×180 sec @ ISO 400, TV-85 at F/5.6, IDAS-LPS, Modified Canon T3.
A bright moon precluded shooting any dim deep sky objects (DSO’s.) Star cluster are still viable targets, though. I had time to kill so I picked the most photogenic star cluster(s) to shoot – the Double Cluster.
The Moon on November 2nd, 2014. 1/500th sec @ ISO 100, TV-85 at F/5.6, IDAS-LPS, Modified Canon T3.
A bright moon dominated the night sky on the evening of Nov 2nd, 2014. I used it as a focusing target before starting to shoot DSO’s. The image came out good enough to post here.
Galaxy NGC 253 on Nov 1, 2014. 17×120 sec @ ISO 800, TV-85 at F/5.6, IDAS-LPS, Modified Canon T3.
I just had to visit my old friend, NGC 253, just to see how it was doing. A bright moon and only a short window of possible imaging time did not let me get much data, but at least I got to see it again.
Mirach and Mirach’s Ghost on Halloween, 2014. 42×60 sec @ ISO 800, TV-85 at F/5.6, IDAS-LPS, Modified Canon T3.
An appropriately named object was chosen as an early evening test target on Halloween night, 2014. Mirach is Beta Andromedae and it is a jump off point for finding M31 and M33. Mirach’s Ghost is that small object very near Mirach that looks almost like a reflection glint of the bright star itself. Nope, it is actually NGC 404, a small elliptical galaxy that just happens to lie in the same line of sight.
Albireo on Oct 31, 2014. 20×60 sec @ ISO 400, TV-85 at F/5.6, IDAS-LPS, Modified Canon T3.Albireo on Oct 31, 2014. Close-up crop.
I started off Halloween night by imaging Albireo, an amazing double star in Cygnus. It was during twilight and there was also some moonlight, so I went with ISO 400 so that I could do 1 minute exposures and get good color and depth.
NGC 6939 & NGC 6946. 100×120″ ISO 3200, TV-85 at F/5.6, IDAS-LPS, Modified Canon T3.
Here’s 3.3 hrs of data on two NGC objects, 6939 and 6946, that happen to be side-by-side in the sky. Conditions were decent and I was able to get plenty of sub-images.
The PacMan Nebula. 38×300 sec @ ISO 1600, TV-85 at F/5.6, IDAS-LPS, Modified Canon T3.
Over 3 hours worth of data in 5 minute ISO 1600 sub-images were used for this image of the PacMan Nebula. It came out alright, I guess. I didn’t have to do much noise reduction on it and it still seems reasonably smooth.
The “Little Dumbell Nebula”. 50 x 180 sec @ ISO 1600. TV-85 at F/5.6, IDAS-LPS, Modified Canon T3.
Here is the “Little Dumbbell” Nebula, otherwise known as Messier 76, NGC 650/651, the Barbell Nebula, or the Cork Nebula. It is a planetary nebula in the constellation Perseus. I had never imaged it before, so now I finally got something on it.
