Moon bombing

[Don Burkett]

The discussion thread that follows the article had me in stitches.


Thank you so much for sharing.


Note to all... Read the thread - insanity and sarcasm at it's best.

If you missed it and wanted to see it I recorded it and have uploaded it to my blog:

ell, I got up at 4am yesterday morning and wasn't able to see the collision.


However, the telescope had been outside for five hours and the scope had cooled completely and the view of the moon was extremely steady. The image was sharp even over 500x.


So I figured, collision or not, I might as well try a picture. I would have liked to get a wider view but the 5DII won't come to focus in the 12 1/2" without a barlow.

5D II with starmaster 12 1/2" dob 3175mm @ f/10 1/40 sec iso 400


The above is cropped to full frame equivalent of about 6400mm. Below is a further crop.

Cool Shots Jon.


I must confess, I had to wiki "barlow".

Fantastico!

[Jon Ruyle]

Thanks!


A barlow is just a diverging lens. Unlike extenders for lenses, there is little or no image quality degridation associated with them. Not sure why. Maybe it is because with telescopes people seem compare like fields of view rather than 1-1 crops. ie, they do the equvelant of comparing the 1200mm focal length scope with a 600mm one cropped so it has the same field as the 1200mm.
