This past winter, we had planned on staying a month at Rusty’s RV Ranch in Rodeo, NM, then head back into Arizona for a few months. After three days in Rodeo, we canceled our Arizona plans and extended to 3 months, but that too would prove not to be enough

My first ever incarnation was a scope with a 100mm mirror and a 25 mm secondary. Construction was pretty basic: 12mm wooden dowels held in 9mm MDF hexagonal sections. The primary mirror was held onto a sprung cell using double sided sticky tabs.

The light from the Sun contains radiation energy across the whole electromagnetic spectrum. It generally radiates as a Black Body with energy peaking around 500 nm.

Deep Sky Imaging

Astrophotography is one, if not the most interesting and challenging fields of amateur astronomy. It is the appealing concept of recording the images of deep-sky objects at distances so great that the light left the object long before the formation of our planet.

When it comes to astrophotography, the right focus is the most important thing. Even the best optics only deliver sharp images if the focus is spot on. A motorized focus has two advantages over manual focusing: it is vibration-free and very precise. If you remotely control your telescope via your PC, you definitely need motorization.

Solar imaging in Ha with small scale aperture telescopes

When the Coronado PST came out, it was a very intriguing device opening to most of us the access to the Ha layer of our sun for an acceptable price.

The Basics of Solar Imaging

Visual observation of the Sun, whether in white-light or in narrow band like H-alpha, rewards the observer with ever changing and close-up views of a major star in action. Features like sunspots, solar flares and prominences, faculae and tiny spicules are fascinating to watch.

AG Optical iDK Scope Review

Back in December I decided it was time to part with my old 10 inch LX200. It had served me well over the years, but with my increasing interest in astrophotography over the years the short comings of this scope for astro-imaging became more and more apparent.

I travel and I camp quite a lot. And I love astrophotography. How can you mix these two? Some time ago, I was using a traditional German equatorial mount, a guidescope and a laptop for astrophotography.

Impression of the Takahashi Mewlon 210 for Astro-imaging

I begin this short impression write-up with some major caveats. This setup is not a typical imaging rig, and I do not encourage first-timers to do this and the targets are usually very tiny around 2 to 3 arc min size.

Back After a Long, Cloudy Hiatus

It has been a month since the last time I was out at my astronomy club’s observatory due to recent cloudy weather. But my first night back out was a good one --no moon, pretty good transparency, and the clouds stayed on the horizon.

A Pentax lens based imaging rig

1+ year ago I started to work on a Pentax lens based imaging system. I saw some wide angle shots that were made with 30 - 60mm lenses that looked amazing.

My First Trip with Remote Imaging

I got into astrophotography at the same time I got into observational astronomy: July 2015, when I was given my first telescope while I was in graduate school.

What my pictures are showing

My main interest lies in capturing images of the nebula's that are out there that are almost exclusively invisible to the naked eye (With the exception of a couple of galaxies in very dark sites, such as M31 and M33).

More short exposures or fewer long exposures –

Which is better?

When I first started out with deep sky imaging, I too wanted to know the answer to this question. Would more short exposures or fewer long exposures be the best way to go for deep sky imaging?

Imaging with a C8

When I’m speaking about the history of Schmidt Cassegrains at star parties, club meetings, or cons, I often get puzzled looks and questions from new amateurs about one of the things I say: “One of the big reasons for the 8-inch SCTs becoming the most popular commercial telescope in the 70s was astrophotography.”

The Differences between CCD and CMOS Sensors
