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

Magnificent presentation of "The Wishing Well" open cluster Scott. Stars are rich in colour and exhibit good balance. The sky background does not appear flat but this is slight and does not detract from the beauty of the cluster. Great work.
Hi Scott,
When I mentioned the sky background not appearing flat, I wasn't referring to the faint red nebulosity, more the strong vertical band of blue along the right border. Using the PS equalize function, you can emphasize the colour shifts/gradients in an image to determine what adjustments you need to make and where. See attached. As I mentioned in the previous post it does not detract from the original image, but when you know what you are looking for it is apparent. Just trying to lend a hand and give sound advice to better your images - certainly not having a shot at you.
