A little bit of a catch-up...

Sorry not posted for a while but i've been hard at work getting to grips with the new camera - namely the Altair Astro Hypercam 533C ProTec.
This is a (thermoelectric cooling) tec cooled camera with a square 3000x3000 sensor and no amp glow!!.
It also has slightly larger pixels that the 183C so affects the resolution and how I bin or not bin an image - with my refractor I do not bin and with my reflector I do bin 2x2 - both are reduced by 0.8x.

[Binning 2x2 effectively reduces the image by half and makes the camera more "sensitive". It also helps with managing the resolution.]

However, the images below are not binned. All taken with an offset of 40 and gain of 200 using the SkyTech LPRO Max filter. Stacked in Deep Sky Stacker and processed in Affinity Photo.


ED80 Refractor. Crescent Nebula (NGC6888). 5000 light years away in Cygnus. Total 52mins.


6in Ritchey–Chrétien. Albireo. Double Star at 420 light years in Cygnus. Beta Cygni A is the amber star and Beta Cygni B is the blue-green star. Current data supports that they are only an optical double and not a binary system. Total 30secs.


6in Ritchey–Chrétien. Ring Nebula (M57). A planetary nebula 1.3 light years away in Lyra. Total 19mins.

Clear skies.
