I've been given the unique opportunity to review a new Ritchey-Chrétien Telescope, the iOptron Photron RC6. This telescope has a longer focal length than any of my refractors, which I plan on putting to good use. The impressive 1370mm focal length means that this stocky red Ritchey-Chrétien is a perfect choice for astrophotography during galaxy season. I'm looking forward to some large, high-resolution images of galaxies such as M101, the Pinwheel Galaxy. With this added "reach" also comes an increased demand for focus and tracking accuracy. Added challenges include a strong need for an e…

In the following post, I'll share my experiences using 2 astonishingly affordable camera lenses for astrophotography. I shoot with both full-frame and APS-C sized sensor Canon DSLR's, so the lenses are both made by Canon. The Canon EF 50mm F/1.8 STM, and the Rokinon 14mm F/2.8 wide angle lens…
