shadows

Posted By Alan Friedman
Hi Alvaro,

These are mountains adjacent to the crater Plato (just showing in the bottom left of your picture. They do cast very dramatic shadows when the terminator is close by. Do not know how tall they are but I bet they were even taller before the lava flow surrounded them?

best regards,
Alan

What would be a good mount for AP155?

Posted By Alan Friedman
Ashton -

I would suggest signing up for an A/P 900 and using your G11 for now. It will probably work OK at F7. The 900 is a superb mount and like the 155 will be worth the wait. I think that the wait for the mount will not be as long as for the telescope!

clear skies,
Alan

Just beautiful! And your secondary spider contributes a lot to this image.

Excellent image. NGC 253 barely reaches 20° above the horizon here. Thanks for giving us a look.

M42 with Canon 10D

Posted By Alan Friedman
Wow!

I had a CN212 at one time - cassegrain config was very nice planetary scope - but never good results in the newtonian config. Did you crop the image very much?

Saturn on Boxing Day

Posted By Alan Friedman
Mark, Ivan, Wes, Rolando -

Thanks for your kind words.

This technique seems to have promise - especially for those of us up north. The seeing in Buffalo usually produces just a handful of frames that are sharp across both ansae, and even the best frames are not the same shape. The stacking averages these, but fine detail always suffers. Using several locations for alignment produces sharply focused regions, but then masking must be used in Photoshop to apply the focused areas to the image without softening other areas. But when it works, the extra time seems well spent!

clear skies to you,
Alan
