Baader T-2 / 15 mm Extension Tube (T-2 part #25A)
I am trying out eyepiece projection photography using Hyperion Universal Zoom Mark IV together with
Televue 60mm ApoTelescope and
Canon 800D/EOS Rebel T7i (US) with 1.61 Crop factor (APS-C ).
What is the extension tube length that I should be using ?
(I tried with 30mm extension but still cannot get anything on the camera sensor; Been trying out at focal length of 8-24mm on the eyepieces but still nothing. ) . Am not using any star diagonal in between. Any advice?
Answer rated: 0We recommend 30mm distance between camera and eyepiece for APS-C-cameras, as described in this PDF: https://www.baader-planetarium.com/en/downloads/dl/file/id/444/product/1211/digiscoping_camera_adaptations_for_afocal_photography_and_eyepiece_projection.pdf
The focus position with the camera should be quite close to that of the eyepiece, when you look at it with your eye. If you can't reach focus for visual observations without the star diagonal, then you should use it also for photography (or some extension tubes between focuser and eyepiece).Answer by: Baader Web Team (Admin) on Nov 26, 2020 10:19:00 AMRated: 0

Filter cell 2" classic (8mm height)
Are there any instructions on how to unmount and mount filters? I have an Optlong l-extreme that only had threads on one side and is unusable until I found this product.
Answer rated: 0We do not have a set of instructions, but there are tools available for opening camera lenses (basically two screw driver tips where you can set the distance in between, which you can also use to unscrew the locking ring inside of the filter cell. We recommend that you remember which side of the filter faces the telescope, or put the more shiny side towards the telescope to avoid reflections.Answer by: Baader Web Team (Admin) on Nov 24, 2020 10:57:00 AMRated: 0

Alan Gee Telecompressor Mark II (T-2 part #20)
I have a new C11 EdgeHD with a Celestron OAG. Will this work with what I have for imaging and if so what adapters do I need.
Answer rated: 0The original Alan Gee was designed for Schmidt-Cassegrains and will not work with an EdgeHD for photographic use - it can't be installed inside of the baffle.
The UAG-II can be used with a binoviewer at an EdgeHD, because it still works fine with the relatively small image circle of a binoviewer (1.25") even on an EdgeHD. But we do not recommend to use it so far away from its optimum position with a camera, where you will notice any aberrations further away from the center of the field of view when you look at the image. Even with a binoviewer, you shouldn't add the additional light path of an Off-Axis-Guider.
For photography with an EdgeHD, you should use the original Celestron reducers specifically designed for the EdgeHD - then you have a system which is optimised to work.Answer by: Baader Web Team (Admin) on Nov 24, 2020 11:02:00 AMRated: 1

Baader UV/IR Cut / L-Filter
In the description for this filter it says the UV cutoff point is at 400nm: "Blocks UV below 400nm and IR above 680nm"
But in the specifications it says the transmission range is 420-680nm. So which one is it?
Answer rated: 1Blocking starts at 420nm; 400nm are completely blocked, as seen on the transmission graph.Answer by: Baader Web Team (Admin) on Nov 24, 2020 10:34:00 AMRated: 0
