This is a crop of my original image which consisted of 16 2min25sec shots ISO 800 Canon 400d and 8 darks with flats applied ( I think ) taken on Friday night through Williams Optics FLT 110 and guided with PHD, Stacked DSS and processed in PS CS3. This image is only 15.3Kb so I hope it posts OK.
Mark when I see you next, remind me to show you how to use Photoshops Save for Web and Devices option. It will help you achieve an optimal image for uploading.
