Wide-field Wonders

Here are some wide-field vistas captured using an Atik 460ex OSC camera with a 100mm camera lens attached.

The first is of a region in Auriga, around M36 and M38. The HII regions haven’t come out quite as well as I’d hoped: The Flaming Star nebula is on the right hand edge of the picture with IC410 to its left. M38 is the cluster above centre, while the one to the left of centre is M36. 30 x 5min exposures.

Next up is a colourful region in Gemini. The two bright stars are μ (on the left) and η Geminorum, while open cluster M35 is visible above. The Monkey Head Nebula (NGC2175) is visible lower right, while the fainter HII region IC443 aka the Jellyfish Nebula can be seen between the two stars. 15 x 5min.

And finally, a view of eatern Leo. The bright star upper right is θ Leonis, and the Leo Triplet of M65, M66 and NGC3628 can be seen below. There are three other small galaxies in there as well (NGC3593, NGC3596 and NGC3655), if you know where to look 🙂 15 x 5min.

The Leo Trio

No Spring observing season would be complete without imaging this group of galaxies in Leo – M65, M66 and NGC3628. This image was the first one I’ve tried using my Canon 400D through the MN190, and although I could have had better flat frames, it still came out reasonably well. It’s a stack of 18 x 5min frames at ISO 800.

Leo Triplet

Well, I’m still struggling a bit with getting autoguiding working. It was behaving itself intermittently last night while I was trying to image the Leo Triplet of M66 (lower left), M65 (lower right) and NGC3628 (top). Unfortunately, the camera was sest to take low-res jpgs, instead of raw , so the picture isn’t great 🙁 15 x 2min exposures @ ISO800 through the ED80.
