Adapter M68i to M63a (Feathertouch 2.5", TS-Optics)
Will this M68 to M63 adapter work with the telescope side of the 2” ultra low profile M68/M60 eyepiece clamp? (so that the 2” ultra low profile clamp can then be attached to a M63x1mm female threaded telescope draw tube)
Answer rated: -1Unfortunately this won't work because the M60 thread of the 2"/M68 Ultra Short clamp #2458196 wont fit into the 58mm clear diameter of the M63a/M68i adapter. It will work in combination with a 7.5mm M68 extension #2458212 in between. Alternatively you could of course also remove the M60 thread on a lathe.Answer by: Baader Web Team (Admin) on Sep 22, 2021 4:26:00 PMRated: 0

Glasspathcorrector 1:1,25 for Baader-Binoviewer with Zeiss ring dovetail (MaxBright® II and Mark V)
I would like to know how to check the way of the lens of 2456314Z or 2456314. Because I forgot whether my 2456314 was modified the way of the lens cell for markV which is used with newtonian GPC currently.
Best regards
Yutaka Takagi
Answer rated: 1The side facing the telescope is convex, the side facing the binoviewer is almost flat - respectively a little concave.Answer by: Baader Web Team (Admin) on Sep 21, 2021 7:13:00 AMRated: -1

Universal Red Dot Mount RDM
Can you please tell me the center to center spacing between the two threaded holes for M5 hex screws that attach RDM to the dovetail base? I am planning to order a custom V-style clamp that will attach the RDM to a vixen dovteail bar, and will need this hole spacing to have the counterbored holes machined into the part.
Answer rated: 0The required spacing is 20 mm. We included also a new image that illustrates this better: https://assets.baader-planetarium.com/media/extendware/ewimageopt/media/inline/1e/8/universal-red-dot-mount-rdm-eb0.jpgAnswer by: Baader Web Team (Admin) on Sep 21, 2021 12:45:00 PMRated: 0

Baader 3.5 / 4nm f/2 Ultra-Highspeed Filter-Set – CMOS-optimized (H-alpha / O-III / S-II)
I'am using de 2" Ultra High Speed filters Ha, SII en OIII for my C14 Hyperstar. Can you tell me which side of the filter should point to the camera? Or does this not matter.
Answer rated: 0In mounted form the male thread must point towards the camera. The filter is already mounted in the cell in the correct way to achieve this.Answer by: Baader Web Team (Admin) on Sep 21, 2021 9:23:00 AMRated: 0

Baader S-II Narrowband-Filters (6.5nm) – CMOS-optimized
Is the Baader S-II 2" Narrowband-Filter (6.5nm) – CMOS-optimized the same as the discontinued Baader S-II 8nm CCD Narrowband-Filter 2" would the CMOS optimised version be parfocal with the older standard CCD versions of this filter?
Answer rated: 1If your optics is so well color corrected that parvocality only means to keep the filter thickness the same as befoire, then indeed the new CMOS-optimized filters are parfocal to all Baader-filters as we try to keep the substrate thickness consistent troughout all our filters.
Otherwise we want to confirm that the new CMOS-optimized filters are on a much higher level of coating technology compared to the previous ones.Answer by: Baader Web Team (Admin) on Sep 13, 2021 8:34:00 AM
