Gerhard,
you are welcome
Just one little question; with your ASA mount, is it true that it is unnecessary to "autoguide" it.
I heared that it could give pinpoint stars; unguided for takes longer than 20 minutes?!?!
I am asking this for two reasons:
1. Why did you choose your "short" 300s exposures?
2. I am considering to buy me one of these mounts and optics in the future and I am trying to gather experiences of owners.
Thanks
Cheers
Lex
