This is an upgrade of my Mark 4 with different camera and several additions including Peltier TEC cooling to reduce noise and using the Raspberry Pi for image capture and control. In addition I shall be using WiFi to connect from a desktop computer for control and image transfer. I'm currently learning how to use the RPi almost from scratch - I have used Linux in the past.
First proper go at the Veil Nebula last night. I've selected the best data with 19 lights of 240s at ISO 1600 plus 35 darks and EXIF T of -15C. Stacked in DSS which chose 15 lights to stack. No flats or bias frames as yet. Processed in PS, scaled to 1024px wide and saved as PNG. I also have 22 lights of 120s which I shall try adding later.
A new version of my ASC using a new imaging camera for lower noise and higher resolution but with the same Fujinon zoom lens. Previously Mark3. I bought a ZWO ASI185MC for planetary imaging but the weather and short dark periods at this time of year are discouraging me from this. This camera should make a great all sky camera in conjunction with the Fujinon zoom lens. The 2.5mm lens supplied with it doesn't quite give the 180° coverage I would like and doesn't have an aperture control. The ASC needed a rebuild of the drive system and electronics as I'm changing to two 28BYJ-48 12v stepper motors for focus and aperture control instead of a micro servo motor for the aperture, which proved unreliable.
