"Alan Shank" wrote in message news I have a Discovery 14" Dobsonian. Can you use the Meade DSI on such a scope? Cheers, Alan Shank Yes. That is, as long as you aren't expecting to take long exposures (you'd need to guide the scope to do that anyway. But for solar, planetary and lunar work, yes you could use this camera with your scope. If that is all you are planning to do then you would save money and get better results using a webcam (Though you will have trouble getting the best results with an undriven scope, as once you are at high enough magnification to give you the best resolution, you will find it difficult to keep the target in the frame, tracking manually.) Robin While I have personal reasons why I advise anyone not to support Meade, objectively I thought they were offering a webcam plus software package that was priced about the same as if you had to go out there and get it all yourself, and worked well as a package, probably because they didn't invent most of it. But if you can get the right webcam at a discount price that combination is hard to beat price-wise. Hi David, The DSI is not actually based on a modified webcam, but is a camera designed from the ground up for deep sky imaging. (How well it works in that application I will leave others to judge) It is not however optimised for planetary work and is at a disadvantage compared with the webcam for this application. Here in the UK at least, the best webcam for the application (a Toucam Pro II ) plus adapter and IR blocking filter can be bought for less than £100 (some excellent capture and processing software is available fee on the web) compared with £250 for the DSI. I expect the price comparison is closer in the US though due to Meade's pricing policy in Europe. Hi Robin, I wasn't exactly referring to the DSI, but I thought Meade had a webcam-like device for sale. Maybe I was thinking of something from Celestron instead. Sorry for the confusion. -- Sincerely, --- Dave ---------------------------------------------------------------------- It don't mean a thing unless it has that certain "je ne sais quoi" Duke Ellington ---------------------------------------------------------------------- |
