100% Dedicated to Astrophotography
IMAGING THE SUN
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.
Image Processing in Photoshop: Bringing Your Time and Effort to Life
You’ve just spent hours, or even days or weeks collecting data for your latest object. You stack up all of your light frames with your calibration frames (darks, flats and BIAS) in DeepSkyStacker and let it do it’s thing.
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.
Explore Scientific Carbon Fiber ED165 f/7 APO Triplet with Ohara FPL53 optics and Starlight True 3″ Focuser
Reveal celestial wonders like the desolate beauty of the lunar terrain, the serene structure of Saturn’s rings or the brightest deep sky treasures of the Messier catalog with Explore Scientific’s 165mm FPL-53 Apochromatic Refractor.
Pate's PiKon telescope
I pretty much accidentally ran across an interesting YouTube video describing a telescope built around a Raspberry Pi (with it's camera) using mainly 3D-printed parts.
ASTROPHOTOGRAPHY ON THE GO
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.
First shot of the season in the constellation Orion! I set up the AstroTech RC scope (6"/152mm aperture f/9) with my narrowband imaging train, Atik 414EX, ZWO filter wheel with Clear, Ha, OIII, SII & IR685, William Optics 0.8x field flattener/reducer that brings the AT6RC to f/7.2 at 1080mm focal length.
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.
SkyWatcher Evostar 72ED Review
I just bought my first real telescope – the SkyWatcher Evostar 72ED! I have been looking for a beginner astrophotography telescope for a few months (upgrade from a telephoto lens), and the time to choose finally came.
Celestron CGX Equatorial Mount: Unboxing, Setup, & First Impressions
Since the spring of 2014, my main imaging rig has been based around my Celestron AVX. This is a fantastic go-to equatorial mount of the EQ5 variety, handling visual payloads of up to 30 lbs.
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?
amyang 800mm Lens Review:
A Night & Day Companion
The Samyang 800mm MC IF f/8 is a manual focus, fixed aperture mirror lens made in Korea. It is a well-built metal construction styled in black and white.
Small Refractor Mods
There were several high-quality 60mm apochromatic refractors that entered the market last year. They were pitched as portable wide-field scopes, and also marketed here in the US for the solar eclipse last summer.
The Curious Case of the Schmidt Cassegrain Telescope
As you may know, for years I was one of the leading proponents of the Schmidt Cassegrain Telescope (SCT), and am one of only two people to have ever written a (commercially published) book about the telescopes.
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
GETTING MORE OUT OF YOUR EQ MOUNT
In less than 3 years I have built the almost, unenviable reputation for mount tuning. As one of only a handful of mount tuning businesses world wide we can safely say we're pretty experienced at what we do.
Full Frame vs Crop Sensor: Is Full Frame Worth The Extra Cost?
Full frame, crop sensor DX, APS-C, FX, full frame equivalent These are terms that get thrown around a lot when it comes to digital cameras and lenses.
