2" Nosepiece with 2.156 Threads for QSI and SBIG CCD Cameras and 48mm Filter Threads (A2558)
Brand : Astro-Physics
- In Stock
The A2558 2" Nosepiece is similar to our classic AP16T 2"/T-2 Nosepiece, but with 2.156" threads for QSI and SBIG CCD Cameras. This nosepiece features a tapered profile that will provide the most robust attachment possible. Attach it to your CCD camera, insert the nosepiece into your 2" adapter and tighten the thumbscrews. The brass locking ring will seat your valuable CCD camera squarely and solidly into place.
The nosepiece has 48 mm filter threads and the interior is painted flat-black. It is compatible with most compression locking rings. However, it is not recommended for our 92 mm f/5 or f/7 Stowaway (2" Focuser), or when using our older style 2" Thin Adapter ADA2013 (or prior version ADA201). When using these older designs, we suggest the BP16 nosepiece. The current stylewill work perfectly with the A2558 nosepiece.
To see the nosepiece as used with a CCD camera, review this . If you own an Astro-Physics focuser, you also may wish to consider our that features 3 locking screws. The combination of these two accessories will redefine "rock solid."
This nosepiece has a net spacing distance of 0.25" (6.35 mm).
It has a nose insertion depth of 1.125" (28.6 mm).
This nosepiece when used with the CCDT67 has a net insertion depth of 2.57" (65.4 mm) .
