Thanks guys!
Well, well, well….what a small, yet wonderful astro community we have here, on Ice In Space and in particular, in SE Qld. After posting the above image of Saturn and mentioning my disaster with a Bob’s knob shearing off, (head only), I was contacted by Peter Marples and Tony Surma Hawes to be informed that Sirius Optics at Underwood (Ron) has a set of Mewlon Bob’s knobs in stock! Thanks guys!
Since my original post, I have temporarily re-fitted the original Tak collimation bolts and will pick up the spare set of Bob’s knobs when I next pop in to see Ron and Peter at Sirius.
Nothing is ever easy though. I found the Tak 2” adapter “rocked” in the Moonlite focuser due to the shallow depth and grub screw cut out in the Tak 2” adapter. This meant that the collimation kept “changing” as the adapter wobbled in the focuser.
Finally, after cobbling together a series of T2 to 43mm to 54mm to goodness knows what step up/step down rings and adapters, I managed to fit the Tak collimating ‘scope to a deep 2” adapter which seated firmly in the Moonlite focuser.
I’ve just finished touching up the collimation using the Tak Collimating ‘Scope so hopefully, a small tweak or two under dark skies should get me collimated again, if the clouds cooperate that is!
Cheers
