"OnAxisLock 50,8mm visual back for SC telescopes with 3,3"" thread"

PrimaLuceLab
OAL508SCL

OnAxisLock 50,8mm visual back for SC telescopes with 3,3" thread is screwed directly onto the rear thread present in Celestron C11, C14 or EdgeHD 925, 1100, 1400 telescopes and lets you use all the 50.8mm diameter accessories.

OnAxisLock is the accessories locking system that, compared to the one using normal screw, offers a greater clamping force, avoiding any possible flexure (so it's perfect for astrophotography), it does not damage the connected accessory and it perfectly centers the optical axis of the telescope. All this thanks to a new locking device with double ring: just rotate manually the appropriate outer ring (designed to allow an easy grip, even with gloves) in order to obtain a perfect closure!

During use of heavy photographic instruments like DSLR or cooled CCD cameras (often with filter wheels ), it's crucial to avoid flexures when we insert them into the telescope's focuser. This also important for visual use using large mirror diagonals and wide field eyepieces (which are often very heavy).

That's why we designed the OnAxisLock adapter that replaces the classic screw with a locking ring system. This allows you to perfectly lock the inserted accessory by rotating the outer ring (red): a special double ring tightens internal accessories with an uniform pressure. The OnAxisLock device also allows you to keep perfectly aligned the accessories inserted in the focuser: so you will be sure that your camera's sensor will be perfectly centered with the optical axis of the telescope.

 

 

 

 

 

OnAxisLock 50,8mm visual back for SC telescopes with 3,3" thread is screwed directly onto the rear thread present in Celestron C11, C14 or EdgeHD 925, 1100, 1400 telescopes and lets you use all the 50.8mm diameter accessories.

So it's perfect for photographic use: you can screw it on the rear thread of the SC telescope and, adding a normal T2/2" adapter, you can connect most of DSLR and CCD cameras. This assembly scheme, compared to the use of the classic SC photo adapter, lets you use 50.8 mm diameter filters, that can be screwed in front of the T2/2 " adapter inserted into the 50.8mm OnAxisLock adapter.

The particular locking mechanism also avoids spoiling the inserted accessory because the pressure is evenly distributed in the barrel. With the classic screw locking system instead the stress is instead carried on a small area and this can easily spoil the barrel.

 

The special design of the outer ring has been developed to allow you to lock the accessory with ease, even when wearing gloves. This way you can be sure to safely lock your CCD camera or your eyepiece even when the cold is intense.
