This is Sharpless 101, aka the Tulip Nebula, in Cygnus. Captured with the Atik One and Equinox 80, it comprises 12 x 5min H-alpha, (binned 1 x 1) and 12 x 3min R, G and B (binned 2 x 2), processed in PixInsight.
It was good to get outside last night!! Here’s a quick image of M33 through the Equinox 80. 6 x 5min of luminance, and 5 x 3min each of R, G and B, all binned 2×2. No flats, darks or biases used, although I could have stretched it further if I’d done some flats… I used the new ArcsinhStretch function in PixInsight during processing – it certainly keeps the colour in the stars!
I travelled to the US to see last week’s total eclipse from just north of Madras, Oregon. From our position, we had 1m 30s of totality – nowhere near enough! below is a sequence of frames taken during the eclipse. What I did find interesting – although they don’t show up on the overexposed totality images – was that some solar prominences were clearly visible through the camera viewfinder. The totality images do however show the extent of the solar corona, and the presence of a number of sunspots helps to make the iamges from the partial phase more interesting.
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!
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.
