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.

Fluorite Flatfield Converter (FFC) / 3x-8x
I'm considering Baader FFC for magnifying Venus image through U-Venus filter. Is this better transparency with UV around 350nm wavelength than the other conventional ones such as your VIP 2x barlow.
Answer rated: 0The sharpness performance is definitely better. Only the attenuation through the glass is comparable. In the FFC there are two elements of pure fluorite crystal. This is outstandingly transparent at 350 nm.
But there are two more elements from regular molten glass also in this lens collection. Therefore the pure amount of "normal" glass is about the same.
Nevertheless the transmission at 350 nm should be 90%.Answer by: Baader Web Team (Admin) on Jan 17, 2020 8:11:00 AMRated: 1

Baader 2" ClickLock M74i x 1 clamp (for Skywatcher Esprit, TS-Optics and Omegon)
Hi, would this model work with an ONTC Newtonian focuser:
TS-Optics 2" UNC V-Power?
Thank you
Answer rated: 0The ClickLock clamp does not fit on the UNC V-Power focuser because the focuser has only a M65 thread outside for which we don´t have
a ClickLock available.Answer by: Baader Web Team (Admin) on Jan 13, 2020 10:07:00 AMRated: 0
