I use an adapter from baader, without the extension tube. I can focus on the planets just fine.

do you also have a finder bracket? can you tell me which baader adapter you bought? I took the m44 / t2, but it can't screw

I bought this:

https://www.teleskop...o.php/info/p579

baader told me there is only this adapter ring. how is it possible that on your telementor it can be screwed while holding the finder bracket still? and not me? but do you have the zeiss finder? because otherwise, without anything, it is screwed to me too

You can't use the finderscope with the Baader T2 adapter, unfortunately. Ideally, you need the 20mm long original M44 extension tube with extra long threads and knurled exterior, so you can tighten it enough to hold the finderscope in place. Unfortunately, these extension tubes are INSANELY hard to find.

what I thought. in fact, I would have had a 20mm extension tube made in Italy as I imagined. you are the best! that's why I signed up, because here I know I find passionate and expert zeiss.
what about the other things i was asking about? when you have time. take your time.
Thanks

As suggested by Astrojensen, the original Zeiss 20mm adapter for attaching a 7.5x42 finder is unobtanium. A friend made me an improved 30mm featuring M44 threading and double grooving for a safe adaption of 2" accs.

This shows the "knurled" edition of the Zeiss 20mm Astrojensen was mentioning.

I did not understand: in my case, a 20mm ring is not enough? or do I have to make one of 20 and then others of 10mm possibly to be screwed to the first? and the thickness of the fillet, must it be the same as the original? or if I do it a little longer is it a problem?

You may want to utilize either a 20mm or a 30mm. Length is not critical. The aforementioned adapters are merely meant to tie down the finderscope bracket.

I have seen that by simply using the original zeiss 6cm tube, the finder bracket is screwed. there is only the problem that then with the diagonal and eyepieces, I do not go into focus. that's why I was wondering if it was enough just to make a new 20mm one, with the same thickness as the original pitch. while you have multiple adapters to attach the finder bracket. that's all. I'm just trying to understand, because this is the first time I have to make these kinds of changes. and I don't want to throw money away. thank you very much everyone

The threaded part on the adapter really should ideally be a few millimeters longer than on the 60mm long extension tube, to ensure it holds the finderscope solidly.

I no longer have any, all sold unfortunately… but if we have 10 new potential buyers, Skymeca can make a second run maybe.

No, the threads on it are too short to hold the finderscope ring. I've already tried that.
