Description

The Explore Scientific 5 piece Extension Ring Set 510381 M48x0.75 (30, 20, 15, 10 and 5 mm) contains five extension tubes from 5mm to 30mm length with thread connection M48x0,75mm in a set.

For adjusting different distances of the camera to the focal plane of the telescope or the corrector/field flattener. There is an M48.0,75 internal and external thread in each individual tube. The M48x0.75 thread is also called large T2 photo thread or 2.0 inch filter thread. Camera specific bayonet adapters or color and nebula filters can be used. Included are 5 different tubes with the steps 30, 20, 15, 10 and 5 mm. The larger free inner diameter of 45.0 mm effectively prevents undesired vignetting of the camera sensor. The outer diameter of the sleeves is exactly 50.65 mm and can therefore be mounted directly in any 2 inch diameter eyepiece adapter.

  • Extension sleeves M48x0,75 in set
  • Five extension sleeves: 30, 20, 15, 10, 5 mm
  • Use with correctors and field flatteners

Great for Astrophotography

Nice set of M48x0.75mm extensions. I needed a 20mm to replace my 21mm spacer because my filter drawer is 1mm longer than the common spacer found in astro camera stack. I love that all the spacers come stacked in order and laser engraved all on the same side, nice attention to detail. Also they are 2in outside diameter and can be secured in any two inch focuser. Also makes for a good quick eyepiece extension if you don't want to add focuser spacers when switching between camera and eyepieces. If you need a set of M48 extensions for your backspace requirements, I'm happy with my purchase. Thanks Explore Scientific!
