Horsehead Nebula – 2016/2017

My final result of the Horsehead Nebula (also known as Barnard 33) in Orion. For now at least. Next time I will image this object it will be in the light of hydrogen. For now, this is what 80 minutes (192 frames, each a 25 seconds exposure) of unfiltered data looks like under good conditions (mag +6 sky):

And a smaller version, this time together with the Flame Nebula. This is a two-frame mosaic, resized to 70%.

A crop 100% size, mosaic. A different processing workflow was used:

And the Flame nebula, reworked:

    Very good. I’m a little surprised of the quality of these pictures, especially considering the short time of exposure. It seems that ASI1600 is a good camera. Of course, the quality of the sky is important, but still, for a sensor with relatively small pixel size, is a good result. It would be interesting for everyone if you’ll share your impressions about it.

    • Thank you Dragos! The camera is indeed very good, but in terms of sensitivity the ASI 174MM seems better. Not by much. But the ASI 1600MM in 2×2 binning is better compared to 174MM. Plus it has a bit of extra resolution (in 2×2), and of course much higher in 1×1. A great disadvantage is the low frame rate at high res for the 1600MM. This happens on my rather old laptop, still with SSD drives. Must upgrade this soon. I will comment a bit about the camera in a further post.
