Baader Adapter from 2" SC thread to 2" receptacle - with 2" Filter Thread

Baader 2" SC Deluxe Visual Back with integrated 2" Filter Holder (T2 parts #17A & 17B)

The 2" Deluxe eyepiece clamp consists in the basic version of two parts. The eyepiece clamp and a factory-mounted inner thread ring that reduces the native telescope sided M58 inner thread to a 2" inner thread. In this Version SC-Deluxe eyepiece clamp with 2" filter holder (#2958144), the third part is a M48 filter holder. This filter holder must be threaded onto the 2" telescope-thread to hold any of your 2" filters.

When both parts are threaded onto any SC telescope, the combo looks like Baader´s normal 2" Deluxe clamp, but the performance is much better than any 2" SC-clamp on the market, since the customer may seal the optical tube from dust and moisture and may cut off the unwanted parts of the light for their application, like using a UV/IR-Filter to cut the infrared - or use a nebula filter UHC-S or O III - or any other filter.

Clamping system:

Two knurled screws hold your accessories firmly via a brass clamping ring. The screws can also be operated when you wear gloves.

The advantage of the 2" receptacle at telescopes with SC thread:

With this adapter, you have a fully illuminated field. Star diagonals with SC connection of have a narrow adapter causing loss of light. With this adapter and a 2" diagonal mirror, you can use all the aperture you paid for. Additionally, you can take full advantage of the wide 2" accessory range:

Focal reducers and field flatteners

2" star diagonals

2" eyepieces and adaptions
