CCD vs Film? Lots of time vs no patience? Alright, this is your place to discuss all the astrophotography what's and what's not. You can discuss about techniques, accessories, cameras, whatever....just make sure you also post some nice photos here too!
Just took this picture through my 12.5" Obsession dob + paracorr + 17mm Nagler Eyepiece. The moon just fills up the width of the iPhone5 chip. I got a iPhone afocal adapter and was able to centre the phone quite well to the eyepiece.
"The importance of a telescope is not how big it is, how well made it is.
It is how many people, less fortunate than you, got to look through it."
-- John Dobson.
Think there are 4 obsession telescopes in Singapore. The smartphone with its small lens can match the exit pupil of a large aperture telescope. This image is at around 100x magnification and with a ultra wide angle nagler eyepiece is able to cover more than a full moon. If I were to use 100x with smaller AFOV eyepiece the moon would have been clipped.
