Description

The Keyhole
I´m here at Tivoli Southern Sky Guestfarm where my observatory is located to do some service work on the system.
This is actually a test image after cleaning the mirrors and doing a rough collimation.
I collimated the primary during daylight on Rigel using a Ha filter and it actually is pretty close.
There is a bit of coma I will take care of tonight, but it is barely visible on the focused stars.
The image is just 24min. each filter, but it is a bright object anyway.
