Excellent for hard core solar observers & PhotoI use the photographic model for both visual and photography. I use it with a TV 85 APO refractor and a 152mm Officina Stellare APO triplet refractor.. I was concerned that my TV 85 APO wouldn't have enough in focus for photography. But with the removal of the Click lock and replacement with the Tmount adaptor and my Niikon DSLR it comes to focus with about 3/16" to spare on focuser travel. The other scope is no problem either. Optically this is the ultimate for white light photography. I also have BAADER Astro Solar Film filters that up to now have been my choice. But the Hershel Wedge gives even better results with fine detail and nice crisp images without flare or ghost images. The Solar Conitinuum filter is designed to work with achromats but even APOs will benefit. Larger magnification images hold together extremely well.. The real question is whether the big difference in cost between the Hershel Wedge and BAADER Astro Solar Film is giving the best bang for the buck? If you are only an occasional observer, not a photographer, it may not be worth it. But if you are a hard core solar fan than I recommend it highly. By the way also have a Ha solar scope and while that is fantastic....the two views are very different. If you don't know what I am talking about....read up on the differences and than you can decide if you want to get the wedge.Robert

2" MPCC Mark III (Multi-Purpose Coma Corrector for Newtons)
I would like to connect the MPCC Mark III to a ZWO ASI1600MC-Cooled camera that has 6.5mm back focus.
Do you sell the necessary spacers to do that?
Answer rated: 0Try to use the camera with adapter to get the 17,5mm back focus length. In addition with this ring (set to 37,5mm) you´ll reach requiered 55mm of the MPCC: https://www.baader-planetarium.com/en/baader-varilock-46-lockable-t-2-extensiontube-29-46mm-with-spanner-tool-(t-2-part-25v).html

Baader Sky Surfer V illuminated finder
Will the DSLR hot-shoe adapter that works with the Sky-surfer III, work with the Sky-surfer V? If not, where can I obtain a hot-shoe adapter for the Baader Sky-surfer V?
Thanks for any information.
Answer rated: 1You cannot mount the SkySurfer V on the hot-shoe which can take the SkySurfer III. We don´t know a solution for it but fear that the big
SkySurfer V couldbe too heavy for it and may damage the camera body.Answer by: Baader Web Team (Admin) on Apr 17, 2018 4:53:00 PMRated: 0

Baader Prism Diagonal T-2/90° 32mm
I am interested in using the T-2 32 mm prism diagonal on my Orion ED80 f7.5 600mm f.l. refractor (bought in 2009). It has a 2" Craford focuser that I would attach it to. I would like to know what adapter I need to attach it to the focuser?
The focuser comes with a long 2" eyepiece holder that I want to remove to reduce the focal distance to the point of attachment to the focuser. That leaves the focuser's exterior threads exposed. The exposed threaded tube's dimensions are: ID = 2" OD = 2-1/8" exposed length is 3/8". I can't find a spec on the threads. but I count 10 threads in that 3/8".
My goal is to gain inward focus, increase contrast and clarity, and convert to the clicklock eyepiece holder. My largest eyepiece is a 32mm Optiluxe. As light conditions limit to planetary, I doubt I would get a longer f.l. eyepiece.
Answer rated: 1To attach the prism to a 2" eyepiece clamp, you need the
Baader 2" / T-2 Nose Piece and Camera adapter (T-2 part #16) # 2408150
Orion should use the same focusers as Celestron and Sky-Watcher did on their ED80, so the Baader 2" Four-in-One Adapter M68 (Zeiss) / 2.7" (A.P.) / M60 (Vixen) / M56 (Synta) #2458190 should fit on your telescope, too.
Answer by: Baader Web Team (Admin) on Apr 16, 2018 12:45:00 PMAnswer rated: 1Thank you. Looking up the M68 thread definition, it seems to match my measured dimensions of the end of the OTA tube which I understand is made by Synta.Answer by: Stephen Jackson on Apr 19, 2018 9:39:17 AMRated: 1

Steeldrive motor drive for classic Steeltrack focusers
I have a Steeldrive focuser motor which works fine except that the temperature never has been detected by the handcontrol or SteelGo/ASCOM. The manual suggests to fasten some screws, which has been tried without success. Do you have a solution to this problem?
Answer rated: -1Please try first to check the temperatur sensore by using a voltmeter. The sensore should give back different resistance value in ohm so
you can see if the sensore is defect or may be something else.

Baader 2" ClickLock Diagonal Mirror
How secure is the nosepiece when coupled to the diagonal body? Is there any risk of it loosening when subjected to heavy loads with the diagonal oriented horizontally?
Answer rated: 0The nosepiece is extremely secure and is able to hold even very heavy payload. We've tested it with a C14, see here: https://www.baader-planetarium.com/media/wysiwyg/gross_BP28-AB2956100-06-ClickLockDiagonal-2inch.jpg (but this is not recommended for imitation).
