I was testing the usability of an 8″ F/4 Newtonian with a 3-vane spider. There’s some issues with it, but it takes reasonably good images.
Here’s an M33 that I acquired 57×180 sec ISO 1600 sub-images of data for on Nov 9th, 2012. I used a GSO 8″ F/4 newt with an MPCC that I’ve been toying with lately. Its got that funky spikes thing going on with the 3 vane spider. But, it was sitting around for 5 yrs gathering dust, so I thought I’d put it to use.
I cheated a little for this image since I mixed in a little color from a data set taken with a TV-85 last year that was pretty good. Used Registar. It works miracles when mixing different data sets. Glad I have it.
Comet 168P/Hergenrother on November 5th, 2012. Taken with an 8″ F/4 Newtonian and a modified Canon T3 DSLR.
This is a composite of 3 moon images into one to show the progression of the Moon’s waxing phase. All images were taken with an 8″ F/4 GSO Newtonian telescope.
