I have changed telescopes more often than my wardrobe. My primary interest has always been imaging and I have used a variety of instruments, each with their own strengths and limitations. Over the past 15 years, I have owned the following instruments:
APM LZOS 152mm refractor
TPO 10 in. R-C
Explore Scientific 152ED refractor
Celestron C8, C11, and 11 in. EdgeHD
Meade SN-8 and SN-10
Takahashi FS-60, FS-102, FS-128, Mewlon 210, and Mewlon 250
Vixen R200SS, NA140SS, and VC200L
Orion ED120 and 10 in. Newtonian
William Optics Star 71 APO
Sky-Watcher 100ED and 120ED
My current primary optical tube is a Telescop-Service (TS-Optics) 10 in. f/5 carbon fiber Newtonian. Other current scopes are an Astro-Tech 8 in. R-C, Sky-Watcher 120ED, and Pentax 75 EDHF refractor.
My permanent mount is an iOtron CEM60. I guide with a QHY 5 L-IIM camera on a 60mm guide scope.
My field mount is an Orion Atlas EQ-G. I guide this with the SSAG on a 50mm guide scope.
I currently have three cameras for imaging: and SBIG ST-8300 with an Astronomik 12nm Ha filter and astro-modified Canon 650D (T4i) and Canon 40D.
I use a variety of 35mm lenses for imaging, including but not limited to the following:
SMC Takumar 120/2.8
SMC Takumar 50/1.4
SMC Takumar 35/3.5
SMC Takumar 24/3.5
