I'm still experimenting with this blog.
The October 27 lunar eclipse was an opportunity to try out a new astrophotography set-up out on an easy target. I used a Nikon D100 with a Tamron 300mm f2.8 lens piggy backed on a surplus Meade LXD55 mount and a refractor tube assembly. The image of the Pleiades reached magnitude 10.5 stars with only a 5 second exposure at f4 from an in-town site. Hello resizes and downsamples the images, so there are some drawbacks to this system. Here goes ... Hmm. Slightly blocky looking stars.
