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 old 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.

Baader Hyperion M43 rubber thread cover and eyeshield
Hello, I have question about this product:
https://www.baader-planetarium.com/en/baader-hyperion-m43-rubber-thread-cover-and-eyeshield.html
do you have any photos from bottom side? Is there any metal part like in Morpheus eyecups? Or only rubber like here:
https://www.baader-planetarium.com/en/baader-winged-rubber-eyecup-4243-(hyperion-68%C2%B0).html
Answer rated: 0Unfortunately the Morpheus rubber/metal foldable eyecup #2454655 is our only eyecup with an actual metal thread. All other eyecups, also the one you inquired, consist of rubber only.Answer by: Baader Web Team (Admin) on Nov 25, 2022 12:23:00 PMRated: 2

UV/IR-Cut / L-Filter – CMOS-optimiert
100x100: I need to mount a much larger UV-or IR-filter onto my DSLR-lens than your regular astro 2" filters allow
Answer rated: 0For (much) larger DSLR lens sizes up to 100 mm aperture you might consider our 100x100x3 mm square photometric SLOAN-Filters: https://www.baader-planetarium.com/en/filters/photometric-filters.html.
Especially for work in UV, the SLOAN-U filter (#2961707U https://www.baader-planetarium.com/en/filters/photometric-filters/sloansdss-u%27-filter-%E2%80%93-photometrisch.html#425=1695) is a viable alternative to our time proven U-Venus-filters (https://www.baader-planetarium.com/en/baader-u-filter-(venus-and-uv---350nm).html") - offering a very similar transmission window but up to 100 mm sq size: https://www.baader-planetarium.com/en/sloansdss-u%27-filter-%E2%80%93-photometrisch.html
There even is a clever way to hold that huge size filter in front of most any DSLR-lens by obtaining this holder and doing a minimal change that converts this holder from accepting two filters of 2 mm thickness into accepting just one filter w. 3 mm thickness - with a mere screwdriver (sorry for the german Amazon-link): https://www.amazon.de/dp/B07FL3YNHB?pd_rd_i=B08KVZ8VWT&pf_rd_p=5f9972c1-184d-4e29-822a-e867654f66c0&pf_rd_r=5T5PNXXSSA4JVTRSN3QK&pd_rd_wg=6HR08&pd_rd_w=dE1wF&pd_rd_r=e8cc1e1b-747d-4193-acdf-981d7f2e81e4&th=1Answer by: Baader Web Team (Admin) on Nov 25, 2022 8:54:00 AMRated: 2

VIP 2x modular barlow lens, visual and photographic
I have this VIP Barlow, along with all the Morpheus eyepieces. I would like to configure this Barlow so that I get 1.2x magnification, or as close to that as possible. As it comes out of the box, the lowest magnification with the Morpheus is 1.53x.
Baader has a lot of parts in their catalog, too many for a novice like me to sort through - is there anything I can acquire to convert or make the VIP element a 1.2x Barlow?
Thank you!
Answer rated: 1According to our optical calculation, the VIP-Barlow would show considerable amount of field curvature if used below 1.5x.
For this reason we have not designed mechanical parts nor considered ways to go below that value.Answer by: Baader Web Team (Admin) on Nov 24, 2022 9:46:00 AMRated: 1

Bundle: Hyperion Universal Zoom Mark IV with Hyperion-Barlow 2.25x (8-24mm / 3.6-10.7mm)
Does this Zoom EP + barlow work in APM-SD120-APO-90 degree binocular?
Thanks
Answer rated: 0We are delighted that you consider our eyepieces for this APM Bino. Since we don't sell APM products however, we have no further information about this product than what is published on their website. So far we don't see information about backfocus, distance between the eyepiece clamps nor the maximum insert depth of (assumingly) 1.25" barrels.
So these questions ought to be answered (and possibly tested) by the producer. It is solely a matter how much backfocus the designer of the binocular has built into his system and we truly do not know about this.Answer by: Baader Web Team (Admin) on Nov 24, 2022 12:23:00 PMRated: 1

2" BDS-RT Baader Diamond Steeltrack Focuser
Hi, I need a focuser for my 10" orion reflector, I like the 2"BDS RT, can you recommend everything I'll need to mount it? If this focuser won't work can you recommend one of your products that will? Thank you!
Answer rated: 0We are sorry but this question needs to be answered by the dealer that sold the telescope. Unfortunately we do not have tech data on all OTAs on the market.
We agree it is a pity and does slow down focuser sales, but during the last years it simply was impossible to supply the man power, to track down all the relevant data - and it will be a herculean task, given the amount of new OTAS that hit the market every year.
