ALT
Mounts from Eckhardt Alt
ALT mounts cannot shine either through voice control or through Internet support, but they certainly belong to the most precisely functioning and at the same time highest instrument load bearing mounts. For many years, Baader Planetarium has exclusively supplied the mounts manufactured by Mr. Alt, both individually and largely by hand. Mr. Alt has been retired for several years now.
At this point we would like to thank Mr. E. Alt for the many years of good cooperation and wish (albeit with regret) a pleasant, well-deserved retirement.
If you have any service questions concerning ALT mounts, please do not hesitate to contact us, we will forward your inquiry if necessary.
On our www.baader-planetarium.de website we had an extensive presentation of the ALT mounts, which we would like to make available to you here as a reference in PDF form (sorry, German language only). At the current time (January 2019) we still have very few ALT mounts in stock and this is probably the last opportunity to purchase such a mount. We do not offer these as single products on our website, if you are interested, please contact us.

2" BDS-RT Baader Diamond Steeltrack Focuser
I have a GSO RC 8" and I would like to replace the focuser.
What do I need? I am very confused what focuser and how does it attach to the ota.
Thank you.
Stephen
Answer rated: 0As a Ritchey-Chretien is similar in design to a Schmidt-Cassegrain, we'd recommend the 2" BDS-SC Baader Diamond Steeltrack® Focuser
# 2957220 for Schidt-Cassegrains with 30mm travel. It has got 2" (50,8mm) and 3,3", UNC threads (the standard SC-threads).
The 2" BDS-RT Baader Diamond Steeltrack Focuser # 2957210 offers 80mm of focus travel and may be used if there is enough place inside of the telescope for the moving inner part of the telescope (if the baffle inside of the telescope isn't too small).
I couldn't information about the connecting thread of the telescope, maybe you'd have to ask someone to make an adapter to SC-thread for you.

2" MPCC Mark III (Multi-Purpose Coma Corrector for Newtons)
I have a ZWO ASI294MC Pro, which has 6.5mm of back focus, and I want to connect it to my MPCC. In your answer to Keith Krayanek's April 2018 question about a similar camera, you recommended spacers totaling 55mm. But adding 55m to 6.5.mm would equal 61.5mm. Is this number correct? Also, with a M48 mounting surface, do I need a total of 57.5mm of back focus (6.5mm + 51.0mm) or 64mm (6.5mm + 57.5mm)? Thank you.
Answer rated: -1The PDF at https://www.baader-planetarium.com/en/downloads/dl/file/id/343/product/3004/mpcc_backfocus_from_t_2_and_m48_mounting_surfaces.pdf should make it clearer.
In the answer to which you refer, we wanted to make clear that if the customer uses the ZWO-T-Aapter which gives a backfocus of 17.5mm, he can use the VariLock variable T-adapter to get a complete distance of 55mm from the T-2-collar.
So, if you have a camera with T-2-thread and 6.5mm of backfocus (with the T-2-thread), you ned an adapter with a length of 48.5mm. This can be done with a combination of Baader T-2 / 15 mm Extension Tube (T-2 part #25A) # 1508154 and Baader VariLock 46, lockable T-2 ExtensionTube 29-46mm (T-2 part #25V) # 2956946, which is set to 33.5mm.Answer by: Baader Web Team (Admin) on Aug 19, 2019 12:20:00 PMRated: -1

Baader MaxBright® II Binoviewer with case
Is the Alan Gee mark II with a diagonal applicable to the MB II if only the back focus is enough?
Answer rated: 0Yes it is. This will be the same as with the Großfeld-Bino.Answer by: Baader Web Team (Admin) on Aug 19, 2019 10:36:00 AMRated: 0

14 mm Morpheus® 76° widefield eyepiece
I just got the Morpheus 17mm eyepiece and I would like to know if it is possible to remove the 1.25" barrel from the 2" barrel? A 2" cover was included in the box so I assume I should be able to do this. I don't want to have to keep switching my diagonals all the time.
Answer rated: -1There should only be two larger covers be included, for both positions of the eyepiece cup (folded up/folded down) - quite close to two inch, but not exactly.
The 1.25" nosepiece can't be removed without destroying the eyepiece. It is part of the optical design.
If it should be too long for your 2" star diagonal (quite uncommon, but maybe if you have a very low-profile eyepiece clamp and a prism), then you may use a 2"/1.25" reducer. Our Pushfix # 2408151 can even be permanently mounted onto the eyepiece, its silver screw can be replaced with a headless screw.Answer by: Baader Web Team (Admin) on Aug 19, 2019 10:30:00 AM
