There are many different types of telescopes available for those interested in exploring the night sky. The three main types of telescopes are refracting telescopes, reflecting telescopes, and catadioptric telescopes, with many variations and hybrid designs for each type.
A Dobsonian telescope with a healthy aperture is great for enjoying real-time views of the brighter objects in the sky, while a refractor telescope is best used with a camera attached, to photograph faint deep-sky objects.
The main goal of any astronomical telescope is to gather light. Therefore, the two most important factors when choosing a telescope will be your desired focal length (magnification) and aperture (how bright the object will appear).
These two factors will create a unique viewing experience based on the type of experience you are looking for (i.e. visual vs astrophotography).
This week, I returned to my roots and enjoyed some deep-sky astrophotography using a DSLR camera and small telescope. Don’t get me wrong, dedicated astronomy cameras and heavy-duty mounts are great, but my latest imaging session in the backyard was a breath of fresh air. In this post, I’ll share my early results with a…
As the season transitions from summer to fall, the nights have become longer and cooler in the backyard. This is beneficial for deep sky astrophotography for many reasons, with more time to capture exposure time on incredible targets like the Elephant’s Trunk Nebula being one of them. For those that have been following my YouTube…
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…
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…
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 Meade 70mm Quadruplet APO is a high-quality imaging refractor for wide-field astrophotography. This compact telescope utilizes FPL-53 ED glass to produce images with impressive color correction. The quadruplet lens system design results in an ultra flat-field, without the need for an additional field flattener. In November, I was given a chance to test the…
The William Optics Zenithstar 61 is a doublet apochromatic refractor telescope that excels in deep-sky DSLR astrophotography. The Z61 is the most portable telescope ever made by William Optics, a company with a reputation for building beautiful astrophotography refractors. In this review, I’ll tell you why I think the William Optics Zenithstar 61 is a…
Collimating a Newtonian telescope is something every backyard astronomer should experience. In this post, I align my 8″ Orion Astrograph Newtonian for a night of astrophotography in the backyard. My deep-sky target is M101 – The Pinwheel Galaxy – in the constellation Ura Major. With a proper alignment of the mirrors in this reflector, I…
