Question by sel_bos: Can digital SLR take astronomy photo?
Are the exposure time same as film SLR?
Answer by Dr. Sam
Sure. Just set the ISO to a familiar speed. Most default to ISO 200 (some have ISO 100), but may adjust to a higher ISO if you leave it on auto. It sounds like you know what you are doing though, so just check the ISO and go from there.
Orion Telescopes have a great site. Check out http://www.telescope.com/jump.jsp?itemType=CATEGORY&itemID=29 for photo accessories to go with telescopes. You will find a couple of “universal adapters” of interest.
There is also a book about astrophotography that might be a good idea for you.
Also, from any page, click on the link for “Learning Center” near the top of the page. Enter “photography” in the search box and you’ll find 22 articles that will help you.
Sky & Telescope Magazine also has a section on astrophotography available on-line at: http://skytonight.com/howto/astrophotography
