Hi Peter
Firstly, thanks very much for this post. I clicked the link on " how to collimate using a Takahashi etc" and had a lightbulb, or rather a "duh" moment.
I have the RC8 with a moonlight focusser and a tak scope as well as the threaded adapters. As I am very averse to dropping Allen keys on mirrors, I also invested in Bobs Knobs for the secondary.
I also recently picked up. 2.5" flattener plus threaded adapters although natively the field is actually pretty flat but I have a reasonablyv large chip so if I can improve on native that's all good.
My initial issue though was not understanding what I was seeing when collimating however after your post, angels where a-singing and I spent a happy 10 minutes nailing the sucker with the Tak thing.
Waiting for clouds to clear for a star test.
I have made sure that all components in the imaging train are threaded which Paul H highlighted recently.
I have seen some good images (David Naskies for one) from this scope and with upgrades I reckon you are still going to get bang for your buck.
Just wary of spending more on collimation tools than the scope itself is actually worth.
Keen to see how you get on though so keep this thread going please.
Cheers
