VV Cep eclipse

Nice observing run last night. Still some DEC motor lag on my Losmandy Titan mount (I really need to improve how I balance the overall setup!).

I took a spectrum of VV Cep, the binary star whose eclipse is now starting. It is not that obvious but there seems to be some signs of H alpha emission dropping:



Today I did some cleaning inside the dome and remove few things to keep the minimum. Got rid of some fairly large spiders there too... :-)
