Re: Guess the name of this large Lunar Crater with its central peak?

PYTHAGORAS

Geological period: Eratosthenian (From -3.2 billions years to -1.1 billions years)
Dimension: 129.0x129.0Km / 78.0x78.0Mi
Height: 4800.0' / 14500.0ft

Virtual Moon Atlas says that it is in the northwest quadrant, not southwest.

What do I win?
BTW, decent photo :-)

Re: An Oldie but Goodie: NGC7635 The Bubble Nebula

Hi Bruce, Awesome image! For inspiration (and humiliation) I visit Sara Wager's website. Here is her rendition of the Bubble: https://www.swagastro.com/ngc7635.html Astro-Physics' website also shows a cyan bubble: https://www.astro-physics.com/ She did not specify, but I believe it is SHO. Plenty of...

Re: Open Star Cluster M34 using a Newtonian Mask

Tim, That is a tight FOV! You've got good star color. It is amazing what CMOS cameras can do with such short exposures. On the positive side, your FOV would be great for galaxies. M81 Bode's Galaxy will be coming around soon. Give it a try. Here is mine from a year ago. I used Bin 1 for luminance, a...

Re: Open Star Cluster M34 using a Newtonian Mask

Hi Tim, Thank you for your reply! Great questions. The Newtonian Mask adds visual interest. I have a refractor. Refractors render stars as round discs due to the clear, unobstructed path provided by the lens system. Newtonian reflectors utilize two mirrors. The primary mirror gathers starlight, and ...

Hi Robin,

'import socket' works for me, but I am running SharpCap 3.1, second to last patch.

Re: Perseus Double Cluster

Bruce, I went back and scrutinized my frames and discovered that I was badly out-of-focus in G and W12. Red was excellent. I am to blame. I was racing against the meridian. I usually spend more time when focusing but I was rushed. As it is I had to cut short my W12 run when my scope banged up agains...
