Tell me about it. Having these purpose cut adapters if fine but the one for the Vixen can't be rotated and neither can take a 2" filter. I have some 2" fittings working now on both scopes for when the moon is up so I can mount a filter. There are still a few triangle stars in that M20 too. I need to stop playing with those focuser grub screws
I'll have another go at tweaking the collimination at Ron's this arvo.
