Makelllose Sonne mit dem Baader Cool Ceramic Herschelkeil und 4 Zoll APO TriplettUm mich für den kürzlich gestarteten 25. Zyklus vorzubereiten, habe ich mir den Baader Cool Ceramic Herschelkeil mit dem inkludierten 2 Zoll Solar Continuum und ND 3.0 Filter gekauft. Dieser soll dann in der hoffentlich bald aktiver werdenden Sonne zusammen mit meinem Skywatcher ESPRIT 100 und einer monochromen ZWO Asi Kamera Verwendung finden. Anbei ein kleines Mosaik aus 3 Teilen bestehend vom 9. Mai 2020, Mosaik weil ich eine kleine Barlow verwendet hatte. Die einzige Herausforderung war das in-Fokus kommen, - dazu musste ich die 11/4 Zoll "Nase" der Kamera abschrauben, um möglichst nahe ranzukommen, sonst wäre es sich nicht ausgegangen.Michael S.

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

2/26/2021 7:37 PM Baader Single Polarizing Filter
I use 1 1/4 eyepieces on a SOlar wedge. For nighttime observing, I use a T2 Zeiss prism diagonal with a 2" nosepiece (which sits in a 2" focuser). I already have a 1 1/4 " polarising filter which fits onto my eyepieces. Can I combine this with a 2" polarising filter, to be put before the prism, and use the combination as a variable polariser for lunar observation (i.e. one polarising filter before the prism and a second one after the prism, and conveniently rotating the eyepiece to get the desired dimming)? This would be very practical, if it works, but will this setup be less good than a dedicated 1 1/4 inch variable polariser?Is Answered? Yes (1 answer)
Answer rated: 0Yes, sure, this works!Answer by: Baader Web Team (Admin) on Mar 1, 2021 11:55:00 AMRated: -12/26/2021 12:32 PM Baader Solar Continuum Filter (540nm)
Does the Solar Continuum filter block or transmit Infra red or UV?Is Answered? Yes (1 answer)
Answer rated: 0This filter blocks everything from 300 nm up to 1200 nm - except for a "clean" solar continuum-area at 540 nmAnswer by: Baader Web Team (Admin) on Feb 26, 2021 3:12:00 PMRated: 02/26/2021 10:43 AM BCF 2 - DSLR Astro Conversion Filter for Canon Full-Format Cameras (all latest Models)
Is it possible to purchase bcf filter suitable for SONY 3N?Is Answered? Yes (1 answer)
Answer rated: 0We are very sorry, we do only offer the filters for the Canon cameras that you find on our website https://www.baader-planetarium.com/en/filters/dslr-astro-conversion.html There are no plans to produce such filters for other cameras.Answer by: Baader Web Team (Admin) on Feb 26, 2021 10:47:00 AMRated: 12/26/2021 1:54 AM Baader Sky Surfer V (Night & Day Design) Red-Dot-Finder
I would like to attach the Sky Surfer V to an Orion 180mm Mak-Cass. The spacing between the available finder scope screws is 0.75 inches (approximately 19mm). This spacing appears to be too narrow for the Baader Standard Base that comes with the Sky Surfer V. Is it acceptable to use the center hole plus one of the slots to attach the base to the Mak-Cass or to maybe use only the center hole? If neither approach is acceptable do you have a dovetail mounting base that will work with a 19mm attachment screw spacing?Is Answered? Yes (1 answer)
Answer rated: 0It is no problem to attach the base to a round tube only with the central screw - the form of the base makes it impossible that it rotates on the telescope, and one screw is sufficient to hold the weight.
Only on a flat surface or if you can't tighten the screws, you will need two screws.Answer by: Baader Web Team (Admin) on Feb 26, 2021 10:27:00 AMRated: 22/25/2021 12:57 PM Baader 2" ClickLock Diagonal Mirror
Hey! I wonder whether it'll work well with Skywatcher 72ED?Is Answered? Yes (1 answer)
Answer rated: 1It seems that this telescope has a little problem with eye pieces of short focus lenghtes that the focuser cannot travell deep enough (in-focus).
Obviously SkyWatcher is aware of this problem, the tube of the newer models are 10mm shorter.
Okay, about our star diagonal you can find here more information according the lengthes:
https://www.baader-planetarium.com/en/blog/optical-tube-lengths-of-2-clicklock-and-bbhs-mirror-diagonals/
Maybe you can turn in the focuser fully and picture the moon on a white sheet of paper (without eye piece/ star diagonal) so you´re able to
measure the distance with a ruler to find out the back focus length.Answer by: Baader Web Team (Admin) on Feb 26, 2021 9:59:00 AMBaader Planetarium GmbHOur company exists now for more than 50 years.
