Ah yes. Thanks Mark. Dave

If memory serves, the author of the Grabber died and the site died shortly after. ( Sorry if he/she isn't !! ) If you need the stand alone Grabber and nothing else will do, I think you'll have to find someone with it on their hard drive and PM them. Dave.

Sorry I couldn't help more tonight. They do work, honest Dave.

Oh dear ! I have Atik camera Ascom on mine. Have you tried Ascom chooser ? I left all the boxes unticked on mine. ( You'll see the boxes if the Ascom driver shows up ) If the chooser works it even identifies the camera by serial number. If you're using a USB hub, make sure it allows a video type camera to work. I have two hubs that refuse to work with either a DMK or the GP, Dave.

It's - Atik camera ( Ascom ) - on mine. Update your Ascom drivers !! Dave

As no one has specifically answered I'll put neck on the block and say 1 arc min is fine. If I could walk outside each night and be sure to align that accurately I'd be a very happy bunny. In fact, I'll put my neck on the block twice and say you'll be more accurate than some who drift align Dave.

Although I don't tend to use a DSLR, almost all my imaging is with camera lenses. I think Hutech do Nikon filters although no one advertises them so hardly one knows ! http://www.sciencecenter.net/hutech/nikon.htm To give you an idea of what I do look at the 2013 thread post 3 - http://stargazerslounge.com/topic/203802-deep-sky-imaging-showcase-2013/ Lenses suit some but not others Dave.
