Open cluster ngc 3532
Hi
Heres NGC 3532, 2x15 minutes ISO 200. uv/ir filter only, MPCC. 10 inch f5.6 newtonian, fairly poor seeing, guide star was shimmering a lot. Houghys coolded 350D used. I used the toucam once again for guiding , but this time set up my other PC rather then the laptop so I could use the long exposure feature (laptops usb to parallel dongle wont do). I used 0.5 second shots for the webcam, using K3ccd tools and guiding by keeping the star stationary on a reticle on the screen
