Re: [APML] Medium format Beehive and M67

[Ray Butler <ray.butler@nuigalway.ie>]

Hi Colin,

Welcome to the medium format fold! It's always been the best format for 
film-based astrophotography, and these days it is as affordable as good 
35mm gear on the used market, and so are the scanners. So if people want 
to keep shooting the kind of films that are still available, it's the 
way to go.

Your picture came out great. The uniform sharpness is impressive! I love 
the few bright red stars scattered around the Beehive, that contrast 
with the others. I have a Mamiya 645 photo of that field taken with a 
210mm f4 lens, and since yours was taken with a 150mm lens but has been 
cropped, the two are almost identical. But that's a testament to the 
sharpness of your lens.

(I'll see if I can get around to putting my Beehive+M67 on my webpage 
sometime. It's a clunky process! The images are all scanned & processed 
on my non-networked home PC, but I can only access our web server by FTP 
from my work PC, so I have to bring the images in on a USB stick, 
prepare the webpages locally and then FTP them over to the server, and 
load the page in a browser to test if it looks right and the links work; 
if not re-edit locally and re-FTP and re-load...usually several times!)
