Shoot the Moon...

Posted By Alan Friedman
Beautiful shot. At first I felt it was "upside down" but the more I look the more I like it that way.

Thanks,
Alan

That is a spectacular panorama. I wonder if the software mentioned in the September S&T article could help blend the couple of visible seams?

AP 130 vs. maxScope for solar viewing

I think you would be very happy with the SM90 BF30 combo on your AP130. I would recommend spending some time using a SM90 with binoviewers before going to the expense of stacked filters. I find that using two eyes improves greatly the low contrast chromosphere features.

good luck,

Fascinating pictures. That central spire looks like Cleopatra's needle from that sun angle. Wonder how tall it is?

That's a stunning result and a good explanation of FWHM.
Also a great inspiration to what might be done from a less than perfect location - something we all have much of the time.

Very sharp image of sunspot 649. I was looking in H-Alpha and was able to see some of the structure you've captured visually, but it was another thing altogether to capture with the webcam. Nice work!
