Ritchey-Chretien Telescope

A New Ritchey-Chrétien Telescope for Astrophotography

|Telescopes|6 Comments

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…

Up to this point, I have not experienced the joys of shooting through a filter wheel. But I have experienced the extraordinary power of a monochrome sensor through narrowband filters. My latest experiences in the backyard have me wondering if I should have switched to a mono astrophotography camera a long time ago...…

Real Results with a Budget Astrophotography Lens

A great astrophotography lens is only as good as the images it produces. Not all camera lenses are created equal, and imaging a night sky full of stars has a way of pushing your photography gear to its limits. On a recent astrophotography session in the backyard, I discovered how enjoyable it can be to squeeze in a brief mid-week session using a camera lens in place of the telescope. For this imaging run, I used the refreshingly simple and affordable Canon EF 50mm F/1.8 lens. The lens was attached to my Canon Rebel T3i DSLR, which rode atop an iOptron SkyTracker camera mount.
