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

What is the hole diameter of the 3 central holes down the centre of the clamp?

Fluorite Flatfield Converter (FFC) / 3x-8x
If I use the FFC with an F/4.5 Newtonian (16") will I also need a coma corrector for imaging on a full frame sensor or can I use the FFC on its own.
Answer rated: 0Because of the > 3x focal lenght extention of the FFC, you will most likely see just some rest of coma at the edges of the field. But if you place an coma corrector and an FFC in a row, the image quality will degrade in the whole field. Therefore its better to use only the FFC without coma correctorAnswer by: Baader Web Team (Admin) on Nov 18, 2019 3:28:00 PMRated: 0

BCF 2 Astro Conversion Filter CANON EOS 5D/6D MK II
If I modify my dslr with a baader bcf filter inside the sensor, the photos after modification will be only red without any blue or green?Or just more red plus blue and green as before?
Answer rated: 0The Baader BCF is more open in the red part of the spectrum, means all other colours pass the filter plus some more red. This gives "normal" (daylight) photos a pink touch that you can correct in image processingAnswer by: Baader Web Team (Admin) on Nov 18, 2019 8:48:00 AMRated: 0

Baader UFC (Universal Filter Changer)
Will your new upcoming RASA 8 adapter be compatible with 17mm back-focus cameras? Will there be tilt adjustment available for these types of cameras?
Thanks
Answer rated: 0Yes, this latest addition of the UFC-family - the new RASA 8 / S70 UFC-Adapter (#2459136) which will launch on our website very soon - is compatible with 17 mm back-focus cameras such as ATIK Horizon. The UFC allows to change any kind of filter from 1 1/4" up to 50x50 mm square in front of the RASA 8.
The only function, that still might be left to desire, is an easier way to reach the front adjustment hex-screws of the RASA 8. Due to the very short backfocus available, it is somewhat difficult to reach these screws and to "tweak" the star sizes in each corner of the image to absolute perfectness.
So - in order to even reach this goal (exchange filters AND effortlessly adjust the camera tilt), in February latest we will launch a separate product - only produced for the RASA 8: the FCCT (Filter Changer & Camera Tilter). This unit will feature 3D-printed filter sliders and be only able to accept filters in diameters of 31 mm / 36 mm / and 2"(47.4 mm) w/o cell mount. This is a revolution for the RASA 8 since it makes perfect adjustment of all stars in the field a joy. Already now the first imagers are using this solution as prototypes and the results are outstanding, see here: https://www.baader-planetarium.com/en/blog/rasa-8-extreme-images-michael-jaeger-with-ccd-camera-f2-highspeed-filter/Answer by: Baader Web Team (Admin) on Nov 13, 2019 4:00:00 PMAnswer rated: 0The RASA 8" UFC-Adapter is now available:
