EAA Observing Session: 31, January
This has to have been one of the most intensive observing sessions I’ve had to date. 10 observed principle targets, containing a total of 26 objects that have been identified and included in these observations. It was also unusual to have reasonable transparency throughout the session. Normally this is poor early on and starts to improve as we approach happy hour from about midnight onwards, where the seeing settles and the transparency improves. Session…

EAA Observing Session: 2, January

EAA Observing Session: 12, November
Two nights of observing in a row. Now testing Sharpcap’s Multi Star FWHM focusing routine. Works just like the others when it comes to the contrast method but the curve is now inverted. The Lunar images were taken with a mixture of Livestack in Sharpcap as well as video .ser files. Even then, I’m still only downloading about 2 frames a second. This is far too slow so I may have to move my…
