Eudiaskopisches 35mm OkularGelegentlich kauft man Dinge, von denen man hinterher sagt: na ja, geht schon. Gelegentlich aber passiert auch das Gegenteil, nämlich daß man nicht genau das eigentlich gewünschte bekommt, dafür aber völlig unerwartet von einem viel besseren Absolut-Volltreffer überrascht wird. Und eben letzteres ist mir passiert, als ich vor einer Woche statt eines 32mm Okulars von TeleVue Ihr Eudiaskopisches 35mm Okular erwarb! Gesucht hatte ich ein Okular mit möglichst großem realen, jedoch gut überschaubarem und vernünftig randscharfem scheinbaren Gesichtsfeld, das vor allem für das Aufsuchen der Planeten bei Tage geeignet ist. Bekommen habe ich dann etwas, das mit 1,7° am Himmel, hervorragendem Kontrast, sowie Einblickverhalten meinen Wunsch deutlich übererfüllt hat.Prof. Dr. R. Claus

I see removal holes in this adapter for what looks like a spanner wrench. Do you sell a spanner wrench to release the inner ring of this adapter?Is Answered? Yes (1 answer)
Answer rated: 0We do have Adjustable pin type face wrench ø 2mm, # 2450062, but it will not fit into this adapter. However, there are several manufacturers of tools to open and repair camera lenses - with these keywords or "Camera Lens repair tool", you should easily find a suitable tool to reach these holes.Answer by: Baader Web Team (Admin) on Mar 23, 2023 8:55:00 AMRated: 03/13/2023 2:54 AM Baader 2" Cool-Ceramic Safety Herschel Prism Mark II – (Visual / Photo)
I have read that using a Baader IR-Pass Filter just to be extra safe might be a good idea. what do you think of using such a filter with this Herschel Wedge?
thank you!Is Answered? Yes (1 answer)
Answer rated: 0Of course, we will gladly sell you such a UV/IR-cut-filter. It doesn't do any harm, as long as it is of good quality and doesn't cause reflexions.
Such a filter may even be a wise choice if you decide to use the prism with ND-filters by other manufacturers, where you don't know if they let UV/IR pass or not. However, if you use our included filters, they do not only dim the visible light, but also block the remaining UV/IR.Answer by: Baader Web Team (Admin) on Mar 13, 2023 10:34:00 AMRated: 03/12/2023 10:28 PM Baader 3.5 / 4nm f/2 Ultra-Highspeed Filter-Set – CMOS-optimized (H-alpha / O-III / S-II)
If I am using an Edge8/Hyperstar v4/294MM-Pro (21mm image diagonal, 28mm image circle), would I benefit from the smaller filters compared to the larger ones? I want to buy 2” for when I go full-frame, but I need to make sure it will work properly for my current setup as well.Is Answered? Yes (1 answer)
Answer rated: 0At f/10 or even with the 0.7x reducer, you do not need the highspeed filters, the regular filters will work better. To deal with the steeper light cone at faster f/ratios, the filters need to be pre-shifted, so that a ilter for f/2 needs to be different from a filter for f/3 and from one for f/4 or slower.
Please take a look at our filter selector at

I am planning to use this filter with a ZWO ASI2600mc, for matching backfocus with another filters. Considering this camera already has a UV/IR cut filter built in, should I choose a clear filter? Or this filter would give additional UV/IR filtering?Is Answered? Yes (1 answer)
Answer rated: 0You can find the transmission curve of our filter at the product website, if you click on the filter size, and compare it to that of ZWO. Our filter lets light pass between 420 and 685 nm.
If the ZWO already completely blocks UV/IR and starts at the same wavelength, then it doesn't matter if you use a clear or a UV/IR-cut filter. Otherwise, the transmission window is defined by the narrower filter.
I can't find info about the UV/IR-cut-filter of that camera - only a graph for its QE value, which shows sensitivity in the UV and IR, too. So a UV/IR-cut should be an improvement.
But in general, we would recommend the UV/IR-cut-filter, anyway - then you can use it even if you chose sometime in the futur to get a new camera without an integrated UV/IR-cut-filter.Answer by: Baader Web Team (Admin) on Mar 13, 2023 9:11:00 AMRated: 03/12/2023 1:16 PM Baader Double T-Filterholder 1¼"
Will this work with the T2-part #27 on your Herschel wedge with a ZWO planetary camera (direct to the T-thread), I want to incorporate your 1.25" CalK filter. So the order would perhaps be: #27 - #31 (filter inserted) - ZWO camera T thread.
Thank youIs Answered? Yes (1 answer)
Answer rated: 0The adapter will give you a male T-thread on both sides, so you'll also need Baader T-2 Conversion Ring # 2958110
We have also have 1¼" Filter Holder for T-2 and 2" Filter Threads # 1508031. This set contains these two adapters and some more parts, with which you can use the filter either in a T-2-thread or a 2" filter thread.Answer by: Baader Web Team (Admin) on Mar 13, 2023 11:25:00 AMBaader Planetarium GmbHOur company exists now for more than 50 years.
