Hi all -

Apologies for posting yet another image of Clavius (my first).
This was one of the few opportunities I've had to use my new DMK
41AF02.as camera at a long focal length (7.5 meters). This camera has
smaller pixels than the 21BF04. The larger image scale really
requires good seeing - something that has been hard to come by from
my location for some time. This image was made from 120 frames
captured in average seeing. A larger version can be seen here:

best wishes,
Alan

Alan,

That's a sweet Clavius. No apologies necessary - always a pleasure to view your work. BTW, did you employ any filters for this shot?

Hi Alan,

Fantastic image, those smaller pixels do make a difference in image scale alright, I think my Infinity 2-1m has the same size pixels as your 21BFO4.

Thanks,
