The Explore Scientific ED140 Apo Refractor
I am thrilled to tell you that I recently got my hands on a brand new Explore Scientific ED140 CF APO Triplet Refractor. If you've been following AstroBackyard for some time now, you'll know how I feel about APO refractors in terms of astrophotography performance. The refractor telescope design has many unique advantages when it comes to deep sky astrophotography. Specifically, an air-spaced triplet apochromatic optical design will share many of the same characteristics you'll find on a high-end telephoto camera lens. The biggest difference is - they usually reach much further. (The ED140…
A New Ritchey-Chrétien Telescope for Astrophotography
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…
Why I’m Switching to a Mono Astrophotography Camera
A mono astrophotography camera gives backyard imagers in the city the opportunity to collect dynamic narrowband images from home. Although LRGB image acquisition using a filter wheel requires some extra setup time early on, the flexibility of this configuration is appealing. 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...…
