Sorry guys, but I just got my first batch of accessories in the post since buying my scope a few months ago. Might explain the weather around Newcastle...
I've got a GSO 12" Dob and now the owner of a ED 2X barlow, a Laser Collimator (desperate for this), and a GSO Nebula Filter.
I just had a whirl at collimating and its quite easy once you know what you are doing.
On another note, Andrews took nearly 3 months to finally send me this gear and it took a few emails from me chasing them up to get them to explain why it was taking so long. They are a nice bunch of guys but that isn't really a substitute for service IMO. All it takes is a quick phone call. It just seems to me like they are a couple of staff short because they loose track of things and seem quite busy. I was planning this to be my own birthday present but that was back in September...
I guess you get what you pay for.
