Baader now makes the perfect complement to your Celestron NexStar4, Meade ETX , or C90* telescope. The Baader NX4-SC # 2958500A adapter allows you to adapt various photo-visual accessories that use standard 2" SCT thread to these telescopes.
This adapter is one part of Baader's item # 2958500. It has a female 1.375"x24TPI (almost 35mm) thread on one side to attach to your telescope. The other side has a standard male SCT thread (2"x24TPI). With this item you can attach standard SCT threaded accessories meant for larger SCT scopes to your telescope (before doing so, however, make sure that you have sufficient clearance from the telescope's focuser knob so that it does not interfere with your added SCT accessory).
This adapter also incorporates an internal 1.25" female filter thread which allows you to install any 1.25" filter inside the adapter. This allows you to direct couple any accessory and still be able to incorporate photo or visual filters in the optical path. Or install a clear UV/IR cut filter to completely seal your telescope from dust and the elements.
Specifications:
- Total length = 18mm
- Length of male SCT thread = 8.3mm
- Length of female ETX thread = 6mm
- Maximum outside diameter = 55.8mm
- Weight = 1.8oz.
*Important Note: The Meade ETX and Celestron Nexstar telescopes feature a 1.375"x24TPI male thread on the rear of the scope. Many - BUT NOT ALL - older Celestron C90 spotting scopes also feature this thread. It is your responsibility to check the thread on your scope to make sure that this item will work with it. We cannot be responsible for any fit issues if your scope does not have the NX4/ETX thread specified on this adapter.
