Finderscope rings

Saturday, May 31, 2008

Last weekend we made some rings for mounting a finderscope on the main telescope. Today I got the holes drilled and tapped so the rings are ready to use. The gallery below shows the adaptive pocketing paths that were used to cut both the part and the jig that allowed drilling the holes at +/- [...]

Barlow test

Sunday, March 2, 2008

The big picture shows a normal photo through an f=1000mm F/9.8 telescope with a Canon 20D. The field of view should be around 1° 17‘ 20" according to this FOV calculator. The small frame is taken with an additional 2x Barlow lens between prime focus and the camera sensor. It ends up magnifying the image [...]

Moon photo

Saturday, February 16, 2008

When one camera is coupled to the scope the other one can simultaneously take a wide-field photo. Did not bother [...]

Astrophoto test

Saturday, December 30, 2006

I've made a first attempt at pointing my camera towards the night sky. Achieving good results is not an easy task - some people spend considerable amounts of time and money on the hobby of astrophotography ! (and the results are breathtaking) Just a fun thing to do for me - for now... (they call [...]
