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

Baader UFC S70 VariLock 15-20mm extension
Can this adapter be locked at specific proper optical-length position, and at the same time maintain/hold a camera sensor perpendicular to the optical axis of a telescope (perpendicular to 0.01 degree or better, specified by Celestron's RASA manual) ? I've tried to look into the pictures of this adapter and I guess I can figure out how this adapter should be fixed onto other adapters with S70 dovetail, and how it is continuously adaptable on its optical length. However, the adapter seems to me have no locking mechanism to lock on specific optical-length-position, so I'm worried about this. PS.My plan is to add this adapter after two 5mm S70 extension adapters, and install the UFC filter base after this adapter (planed total optical train: telescope side adapter RASA plate->5mm ->5mm ->this # 2459145 ->UFC filter base and a UFC filter slider -> #2459119 S52 and # 2408331 S52-to-Fuji-X adapters -> my Fujifilm mirrorless camera). Thank you.
Answer rated: 1Of course you can lock the S70 VariLock. Adjust the length by turning the knurled outer ring and lock it by turn in the side with the S70 male. To
avoid tilt problems all UFC parts are manufactored very precise. Please hold in mind that some camera manufactorers build in the sensor not
so pretty exactly so you may have to turn the push/pull screws from the RASA anyway.
Okay, after setting the length of the S70 VariLock to 18,8mm (please controll it by using a good caliber) you should have a good start. Or set it
to 19,5mm when using 2mm thick filters. As a rule of thumb the focus point gets lay out to extra focal at a third of the filter thickness (~0,7mm)
because of refraction. To stay homo focal and to receive lights it is of advantage using a clear glass or UV/IF filter.Answer by: Baader Web Team (Admin) on Oct 17, 2018 3:51:00 PMRated: 0

2" BDS-NT Baader Diamond Steeltrack Focuser
Can the Diamond Steeltrack NT focusser be installed on a Skywatcher MN190 without drilling holes?
Answer rated: 0Only our discontinued Classic Steeltrack NT focuser was able using the holes when disassembling the original Sky-Watcher focuser. Then only
when having the focus wheel axis 45° to the OTA axis.
Please notice our website for instructions how to mount the Diamond Steeltrack - as you can see there have to be new holes done to mount it.
You need to have access to the inner tube holding the nuts but the Makstutov Correctore is closing it - I´m sorry.Answer by: Baader Web Team (Admin) on Oct 8, 2018 2:26:00 PMRated: 0

Baader 2" ClickLock eyepiece clamps
I have omegon triplet 102/F7 refractor. I'm not sure the end of focuser tube is S57 diameter or different. I want to change current clamp to baader clamp. thank you.
Answer rated: 0Unfortunately, we do not have the technical data of all telescopes. So, I'd ask you to either measure the dimensions of the back of your telescope and send them to us, or to ask the manufacturer (Astroshop) to provide the data. As they also sell our Clicklocks, they'll probably be able to help you, too.Answer by: Baader Web Team (Admin) on Oct 2, 2018 9:20:00 AMRated: 0

Baader Hyperion Universal Zoom Mark IV, 8-24mm eyepiece (1¼" / 2")
Is this eyepiece parafocal as you move between click stops?
Answer rated: 0We recommend that you focus at high power and then zoom out. Usually, you do not have to adjust the focus then, or only a little bit - this depends also on the possibility of your eyes for accomodation. In any way, there will not much refocussing be necessary - usually it's only the testing to see if you really have already achieved the best focus.Answer by: Baader Web Team (Admin) on Oct 1, 2018 9:18:00 AM
