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. I have owned the following instruments over the past 15 years:
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 254mm Newtonian
William Optics Star 71 APO
My current primary optical tube is an APM-LZOS 152mm f/8 refractor (TMB design). Other scopes are Pentax 75 EDHF and Sky-Watcher 120ED refractors. Although the Pentax was produced in the 1980's, it can hold its own in comparison to most APOs on the market today. It is an amazingly sharp, flat-field scope. It's also quite a rarity. I doubt I will ever let this one go. Also, l now believe that I have the scope of my lifetime with the APM-LZOS refractor.
My permanent mount is an iOtron CEM60. I guide with an Orion SSAG Pro camera on a 200mm f/3.5 Takumar lens.
My field mount is an Orion Sirius EQ-G. I guide with the SSAG on a 50mm StellarVue finder. As you can see in the photos below, I have also utilized other "guide scopes" in the past. I have found that inexpensive M42 mount lenses work very well in this regard. Adapters allow for direct threading of the guide camera onto the lens, providing a very solid unit.
I currently have two cameras for imaging: and SBIG ST-8300 with Baader filter set and a Hap Griffin modified Canon 650D (T4i).
I use a variety of 35mm lenses for
imaging, including but not limited to the following:
Nikon 180/2.8 (pictured above, right)
SMC Takumar 120/2.8
SMC Takumar 50/1.4
SMC Takumar 35/3.5
SMC Takumar 24/3.5
Sigma 400 f/5.6
