This is kind of lost nebula – I collected photons to this frame in September, 2016, then processed them, and forgot to blog it 🙁 So it is not really winter sky object, but, well, its time has come 🙂 That has been also recorded with Atik383 camera, that is now in the hands of my astrofriend Alien (check his content at https://astronomiaamatorska.blogspot.com/ ) . I am pretty happy with my current QHY163M camera, but Atik383 was really my medium format CCD enabler.
In the autumn last year I was totally involved in the dark nebulae. I spend almost all clear September nights on dark side of astrophotography. Barnard 150 nebula is well known dark shape in constellation of Cepheus. I pictured it over two nights 8 and 9 in September, 2016. I used Photoline 130 refractor, Atik383 camera and Baader LRGB filter. I collected 450 minutes of luminance and 3×60 minutes of RGB under suburban sky, and the final outcome you will find below.
Dark nebulae requires good sky to picture them properly, so 5mag NELM is not really a good solution here. However the result is somehow rewarding for me.
