The Rosette Nebula

I can’t let winter go past without having a go at the Rosette Nebula, so before the clouds rolled in last night, I was able to grab a few frames. 12 x 10min Ha and 8 x 3min R, G and B, all binned 2 x 2. It’s just a shade too big for a 500mm scope with this camera…

Five for the Price of One!

Continuing the exploration of HII regions in the Sharpless catalog, here are Sh2-254, 255, 256, 257 and 258 are lurking together in Orion’s arm, close to the border with Gemini, as shown on the accompanying map. This was 15 x 10min Ha, and 9 x 3min R, G and B, all binned 2×2.

Lovely HII regions!

Here are a couple of images from recent nights, taken with the Atik One on an Equinox 80. Both are HaRGB images.

The first is the well-known Jellyfish Nebula, IC443 in Gemini. 30 x 5min Ha frames, and 15 x 3min each for R, G and B. The second is the lesser-known Lower’s Nebula, Sh2-261, in Orion: 20 x 5min Ha frames, and 9 x 3min each of R, G and B, all binned 2×2. I hadn’t come across this one before, and was pleasantly surprised how big and bright it was!


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.


This is an image of the central portion of IC1805, The Heart Nebula, taken with the Atik One through my 190MN. It’s an H-alpha/LRGB image comprised of 15 x 5min Ha binned 1×1, and 15 x 3min each for L, R, G and B, binned 2×2.



The summer break is over, and some decent dark nights are with us. This is the Triangulum Galaxy, M33, captured through the Equinox 80 with an Atik 460EX OSC. It’s from 29 x 5 min exposures, and processed in PixInsight.m33

Spring Galaxies

This shot is of a small group of galaxies in the constellation of Canes Venatici. It shows spiral NGC5033 below and left of centre, while the galaxy above and to the right is NGC5005. Also visible are NGC5002 (right of centre) and NGC5014 (towards the bottom). Galaxy hunters will be able to spot a couple of fainter fuzzies as well. Taken with an Atik One through an Equinox 80, it was composed from 12 x 5min luminance frames (binned 1×1) and 8 x 3min each for R, G and B (binned 2×2).


The Orion Nebula

This is a slightly different view of M42, the Orion Nebula. This narrowband image was captured with an Atik One and 200mm f/2.8 lens using 4 x 10min and 6 x 2min hydrogen alpha frames for the red channel, 4 x 10min hydrogen beta for the green, and 4 x 10min OIII for the blue.


The California Nebula

This is a view of the California Nebula, NGC1499, captured on 7th December. This was put together using 11 x 5min exposures through a hydrogen alpha filter as luminance and red frames, and 11 x 5min through a hydrogen beta filter as green and blue frames. Taken with an Atik One and a 200mm f/2.8 lens.
