Pentax
Refraktoren von PENTAX
Pentax refractors are specialists for one thing above all: They are excellent optics for photography. In addition, the refractors have a very large field of view which is free of aberrations - even without additional field flatteners. This was certainly a convincing argument for Pentax refractors, especially if you think of the always-increasing chip-size of modern digital cameras.
Unfortunately, PENTAX has completely stopped the production of astronomical refractor telescopes. Unfortunately, we cannot order any parts, nor do we have any remaining telescopes in stock.
We are still producing adapters from Baader Planetarium for the Pentax system. With the Baader M68 system we offer an adapter solution for the eyepiece side of Pentax refractors, which allows the use of the complete range of Baader accessories.
On our www.baader-planetarium.de website we had a presentation of the PENTAX refractors, which we would like to make available to you here as a reference in PDF form (sorry, German language only).
There are no products matching the selection.

Baader Wide-T-Ring Nikon Z (for Nikon Z bajonet) with D52i to T-2 and S52
Can I attach the T-Ring to a Takahashi FS-60CB with the Multiflattener 1.04x which has a M52x0.75 thread and requires a backfocus of 87.5mm? Which parts would I need?
thanks
Answer rated: 0The Nikon Z-bayonet has got a flange distance of 16mm, the Wide T-ring adds 8.3mm. So you have 87,5-24,3=63,2mm remaining for adapters. This should be no problem - but we do not have an adapter from M52 to a more common thread.Answer by: Baader Web Team (Admin) on Sep 17, 2020 12:53:00 PMRated: -1

Alan Gee Telecompressor Mark II (T-2 part #20)
I want to use the Telecompressor for visual and i want to know how it need to be use with :
Celestron C11 (no edge)
2956233 Baader 2" ClickLock SCL (3.3")
2956100 Baader 2" ClickLock Diagonal Mirror
2956214 Baader 2" to 1¼" ClickLock Reducer (T-2 part #15B) with 31.5 Eyepieces
In the manual it seem need :
2408150 Baader 2" nosepiece to T-2 / M48 (T-2 part #16)
2958242 Baader Expansion Ring 2"a/T-2i with 1mm optical path length (T-2 part #28)
But it's not clear. Can you explain ?
Answer rated: -1Yes, that is the recommended installation:
Remove the 2" nosepiece from the star diagonal, then you have access to an SC-thread
Insert T-2 Part #: 28 Baader Expansion Ring 2"a/T-2i with 1mm optical path length (T-2 part #28) # 2958242
Place the collar aof the Alan Gee on the T-2-thread
Secure it with 2408150 Baader 2" nosepiece to T-2 / M48 (T-2 part #16)
Then you can insert the star diagonal as usual into the eyepiece holder of the telescope.
You can change the distance to the eyepiece and by this the reducing factor by adding/removing the included spacer tubes or additional T-2 extensions.Answer by: Baader Web Team (Admin) on Sep 14, 2020 1:56:00 PMRated: -1

9 mm Morpheus® 76° widefield eyepiece
On the Morpheus eyepiece is the focal plane at the 2” field stop or the 1 1/4” field stop?
Answer rated: 0Please take a look at the technical data sheet at https://www.baader-planetarium.com/de/downloads/dl/file/id/223/product/2851/morpheus_76_eyepiece_series_technical_data.pdf
Here, you can find the reference plane (the bottom of the 2" nose piece) and the field stop displacement. For most eyepieces, it is equal to the reference plane. Only for the 17.5mm it is displaced by 2.5mm.Answer by: Baader Web Team (Admin) on Sep 10, 2020 10:31:00 AM
