I'm looking for reasons to decide on one of these telescopes over the other, besides price. Currently I am using a Nikon D7100 crop sensor (not modified) DSLR, Tamron 150-600mm lens (effective FL 900mm at 600mm) f/6.3. Guide scope is a ZWO 30f4 mini scope w/ ASI120mm-S camera and all on a Celestron AVX mount. Below is a photo of my equipment. Software is Sequence Generator Pro, PHD2, Plate Solve2.
I like the 900mm FL that I'm now getting and plan on continuing to use my D7100. The main reason for my upgrade is the lens focus is way too temperature sensitive and I have to focus ever 2-3 hours (I'm in Pueblo West, CO-wait 10 min. for the 10º drop in temp or it may rise Would like to automate the focusing but can't on a DSLR lens. Hence - get the tool made for the job!
Would love to hear pro's, con's and problems anyone has had with either of these telescopes especially with a DSLR camera and/or AVX mount (i.e. focus knobs hitting mount?)
Thanks in advance for any info!
