This is a test image with a GSO 8 inch Newtonian telescope and my Canon T3 DSLR.   16×180 sec @ ISO 3200.

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.

Here’s a famous edge-on galaxy that I like to shoot from time to time.   This particular rendition was created with the help of a Meade Schmidt-Newtonian with a 6″ mirror.  Exposure: 50×180 sec @ ISO 1600, modified Canon T3.
