The moon with a P&S ???
Hi! Nik’s recent moon shots inspired me to have a go at it, even though I doubted my P&S results. I used the Shaytech Moon Exposure Calculator. I took it at (4 megapixel) 420mm, ISO 50 (since my camera is very noisy), 1/160, f/8, and it was on a tripod. The autofocus didn’t manage to do its work, and in manual focus, I saw… -
Re: The moon with a P&S ???
Raz, As PF alsready mentioned, P&S can be and actually are used for astro- and seleno-photography quite successfully. You just need some teleconverter -Hubble prolly would be the best, but Palomar would do just fine, too:-) When I posted my shots at the canon 20D forum at dpreview, one of the response I got was a… -
Re: The moon with a P&S ???
P&S cameras are quite capable of very good astrophotographs. They have been used for years by linking them to the eyepiece of telelscopes - google for digiscoping and you will find a ton of links. Generally they are inferior to DSLRs because their sensors are much smaller and the individual pixel wells also tend to be much… -
Re: The moon with a P&S ???
In most cases yes The actual focal length does not depend on the sensor size, it's simply lens assembly property. However the effective focal length does depend on so called FOV crop (or sensor size). For 20D it's 1.6x... For fixed lens cameras they usually specify the effective one, since it looks more advantageous… -

Re: The moon with a P&S ???
Fogot one thing I said yours is 4mp. Mine's 8.2mp. Hence with all other things being equal my 100% crop must be 2+ time larger than yours. Besides, 20D' sensor is known for its good response to sharpening. Two different cameras of the same resolution can respond differently to sharpening process: one can be sharpened a lot… -

Re: The moon with a P&S ???
Thanks Path, you sure had me googling for a while. But putting the noise issue aside, why can't I get those lovely craters? I can see them in Nik's shot, even though it's 20mm shorter than mine :) So, if it's not the focal length, what other factors play a role? Is it also to blame with the small sensor? Thanks Raz -
