I have multiple OTAs that I currently use the Baader Clicklock with. Now I have a Evolution and want the shortest distance from the back of the OTA to the base. I've tried the large Baader Washer thingy, but its too much of a hassle when moving from one scope to another b/c of the dissambly.
I have an old Televue 'Short' 2" visual back which is great, but can't find another b/c its no longer made.
I found this, https://agenaastro.c...sct-barrel.html, and it fits the Baader perfectly, but its just as long as the 'short' TV 2" VB and the regular diagonal set up/insertion.
Then I saw this https://agenaastro.c...agonal-sct.html which looks like it has a really short SCT barrel. The TV 'short' is only 40mm long.
If someone has this, could they measure its barrel length?
Thanks very much.
