Re: [APML] OT: M109, NGC 2403 and other collaboration images

Hi, Jason,

You're right there about the tendency these days to crop and zoom. You can 
easily recognize those images because the star sizes bet larger. Frankly I 
rarely like such images, preferring those where the image scale hasn't been 
forced. Seeing open space around (say) a galaxy image gives it much better 
context and to me makes for a much more esthetic image. (I'm always looking 
for faint fuzzies around the main object, too!) You can tell I'm an old 
timer in the hobby. ;)

Regards,

Greg

Hi Greg,

Yes I agree, except that the common method to expand an image these days is 
to scan, crop, and zoom in something like Photoshop.  Photoshop does 
interpolation when changing image size, which doesn't affect the brightness. 
But you don't get the details of the larger-aperture instrument, so 
"aperture rules" is still valid, but for different reasons.
