FILM ASTROPHOTOGRAPHYWhen I first started imaging in the late 1990's, The Orion Nebula was my first and became my favorite target . This image of the Orion Nebula was taken with a Pentax 35mm film camera connected to my 8" Meade SCT LX-50 in 1997. It is a single exposure about 15 minutes in length, manually guided. (guiding is a discussion for another post, in short manual guiding was a pain!) My first true astrophoto.
DSLR ASTROPHOTOGRAPHYMy astro-imaging hobby took the backseat to other interests shortly there after. It re-emerged late in the fall of 2011. Technology sure had changed in almost 15 years. Now armed with a Canon T3i camera I had recently purchased, one of my first targets was of course the Orion Nebula. This image consists of 5 images, each 2 minutes long, aligned and stacked with software. Guiding was controlled by a laptop. This was taken in December 2011 slightly more than 1 year ago through an 80mm refractor
CCD ASTROPHOTOGRAPHYI continued imaging with my Canon T3i until October 2012 when I decided to purchase a camera dedicated and designed for astrophotography. Having limited funds to spend on my "hobby", I chose a QHY9M CCD. There are many CCD options, but I had seen many excellent pictures taken with this camera and the price was great. In all honesty I wanted to get the CCD before winter to image the Orion Nebula. Here was my result with the CCD and a 102mm refractor, October 22,2012
My camera is a mono CCD, which means it shoots in B&W. This was shot with luminance(clear),red,green & blue filters, 70 minutes of luminance,30 each of red,blue,green.
I have more details on this post
CCD MOSAICSWith the purchase of different filters my imaging of the Orion Nebula continued. This time using a Hydrogen-Alpha filter and the LRGB filters. This is actually 4 images(with the CCD and 102mm refractor) combined in a mosaic to show more area. The hydrogen-alpha filter exposed more "dust" surrounding the nebula, January 18,2013
I really enjoyed creating the mosaic for the image above so I keep expanding on it, 13 panels in the mosaic. It's incomplete and I hope to finish it soon.

My goal is to collect enough panels to fill this field of view. The weather has been an issue for the last couple of weeks, snow,rain,sleet. Hopefully I get a few clear nights soon, there's alot more to do.
