This item is a red dot rifle scope. I have no idea about its suitability for astronomical use. ie - the red dot it projects may be ok for large objects at 2oo metres, but what about a faint fuzzy at infinity? Some of their other products quote 4 m.o.a. for the cross section of the red dot.
Most good red dot astronomical finders us holographic concentric rings, not just a single dot.
Below is a quote from the ebay ad:
- This is an innovative, easy to aim sight for someone who likes to shoot quickly or at moving targets.
- When turned on, a red dot appears on the wide angle screen.
- What you need to do is to put the dot on your target and fire.
- Red Dot Sight
- Fits all 3/8 Weaver Mount
- Fully Adjustable Windage & Elevation
- Perfect for Paintball, Airsoft, Rifle, Pistol with Standard 3/8 sight rail.
A Telrad or Rigel Quickfinder may cost eighty odd dollars in this country but they are a very good investment. Plus they are designed for use with your telescope.
Just my two bob's worth
