Absolutely all the data I have on the Triangulum Galaxy.
Now there’s a LOT going on in this one! Central object is the Jellyfish nebula with bright star Propus. Top right we have TWO open clusters, the larger one is M35, and the smaller golden one to its right is NGC2158. Finally in the bottom right hand corner there is the Monkey Head nebula. Image captured using the Canon 200mm prime lenses with the M26C OSC CCDs. A total of 18 subs at 20-minutes per sub.
The whole of Canis Minor. Canis Minor only comprises 2 stars – Procyon (bright white star bottom left) and Gomeisa (blue star towards top right). This is a 2-frame mosaic using the Canon 200mm prime lenses and the M26C OSC CCDs. The image comprises 37 subs at 9-minutes per sub.
A 2-frame mosaic of the Arcturus region using the Canon 200mm prime lenses and the M26C OSC CCDs. This image comprises 40 subs at 5-minutes per sub. Note the Napoleon’s Hat asterism at the 5 o’clock position.
Lots of Taurus Molecular Cloud dust in this one taken using the 200mm lenses and the ASI 2600MC Pro CMOS cameras on the MiniWASP array. This image comprises 26 x 15-minute subs and could do with at least the same amount of data again.
Here is a larger field of view of the Flaming Star nebula region taken on the 200mm lenses, without stars.
A starless version of the IC410/405 nebulae in Auriga taken on the Sky90 array with the M26C OSC CCDs. Tadpoles clearly visible, and the blue reflection nebulosity in the head of the Flaming Star nebula is very noticeable.
A reprocess of Hind’s Variable nebula in the constellation Taurus. Taken on the Sky90 array with M26C OSC CCDs and UV/IR cut filters. This image comprises 65 x 20-minute subs (or almost 22-hours of exposure time).
This is the second (and final) bit of ancient history that I’ll be looking at today. This time it is Merope (and Ally’s braid) again in the Pleiades, this time from 25/12/2005 (so it looks like I was out imaging on Christmas evening that year). This is also taken on the original Hyperstar (no collimation or rotation adjustment) on a Celestron Nexstar 11 GPS, with the tiny little SXVH9C OSC CCD (1.4Mp). This was (only) 95 subs at 55-seconds per sub, and again we see a glassy smooth (noise free) image, with very little depth.
Sometimes it is good to delve into a bit of ancient history to see how things have developed (or not). This image of Alcyone (in the Pleiades) is from 20/11/2005. It was taken using an original Hyperstar (no collimation or rotation adjustment) on a Celestron Nexstar C11 with a tiny little SXVH9C OSC CCD (1.4 megapixels from memory). This is a massive 312 subs but with only 20-seconds per sub! What do you notice about the image? Well it is glassy smooth and noise-free due to the 312 subs – BUT – it is not very deep, due to the very short 20-second exposures. Win some, lose some I guess.
