The Explore Scientific ED140 Apo Refractor

|Telescopes|1 Comment

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

|Telescopes|10 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…

I have recently had the incredible opportunity to try out an enormous 132mm refractor telescope for some deep sky astrophotography.  Connecting a DSLR camera to a telescope like this is something I never dreamed I would have the pleasure of doing. This is as good as it gets for fans of the apochromatic refractor telescope design. The William Optics Flourostar 132 is an F/7 triplet apochromatic refractor, designed to deliver superior deep-sky astrophotography performance.  The massive 132mm objective lens means that it collects light from objects in space at an impressive rate, which can t…
