Tak OCD

[Trentend]

A bit ocd, but to get focus on all 3 levels on the Binotron powerswitch and FC100 I need just under 1cm additional outward travel to reach focus on the low power setting. This works fine by either slightly pulling out the diagonal or stock extension tube from the stack (per the picture below). But I’d prefer to plug the gap with something so the set up is more secure (and looks better…). Is there a ring or slightly longer extension tube I could use?

A couple of 2 inch parfocal rings might work:

FLO sell a 2" 35mm Tak extension tube. If you remove the 1.25" eyepiece  holder and fit a low profile 2" to 1.25" reducer into a 35mm extension, you may get what you need. Take a look at the Tak accessories or ask FLO for advice.
