M39

The last week has been a little traumatic for the whole family, Our eldest daughter has been waiting to find out if she has the grades to get into Uni. A sigh of relief as she is awarded her primary place at Anglia Ruskin. Congratulations Jasmine. The Younger two have been driving us nuts as they are desperate to go on their sunny holiday and bored of being at home from school.

The RA drive on the mount was very tight and needed a strip down and rebuild, All went well until I ran a test on the guiding. What could be the matter here. PHD would not keep the guide star for more than a few seconds. Lets not panic yet I thought so I ran 60 x 30 second test shots. A nightmare. The subject has moved over a degree across the field of view. The only thing I could think of was the polar alignment. I do my polar alignment using the Kochab clock method. Always worked well for me!! As I looked through the finder the illuminated cross moved, damn, the whole finder had been knocked at some point and almost fell out the holder. Not a great deal more I can do tonight. Next day allowed to me to strip it all down and rebuild and align the polar finder. A chimney pot half a mile up the road stayed where it should be as the pole finder was tightened into position.

A new test on Scheat in Andromeda was perfect. 2 minutes, 5 minutes, 10 minutes was no issue at all.

M39 was the target of choice nearly above my head so I ran 30 x 2 minute guided exposures at 1600 ISO. Processed in Maxim DL & Photoshop.
