The MCDK has been redesigned! We believe this to be the first production telescope with automated collimation and an integrated full aperture guide system. The focuser has been replaced with a motorised secondary mirror, allowing us to replace the previous focuser with a super rigid instrumentation mount point/guiding system. Even the dust covers are automated now. The primary mirror runs on motorised ballscrews and is locked with solenoids. Ideal for remote installations!
If you’re into astrophotography, chances are that a short focal length apochromatic refractor is on your “to buy” list if you don’t already own one. There are prized instruments for their elimination of chromatic aberration and high contrast, true colour images and the tool of choice for many astrophotographers. The problem the “common folk” face with apo refractors is they tend to be quite pricey for even small apertures.

You don't need to have expensive high end setup to start doing Astrophotography.
Technically Dobsonian (Alt-Az design) mounted telescope is designed for Observational purpose only but if you have a Digicam or DSLR capable of connecting to the telescope at prime focus you can do some descent Astrophotography right off the setup without need of expensive tracking mountsetup.
Since planets appear very tiny in field of view (at native focal length of standard telescope) you will need to have Barlow lens 2X or 3X to achieve higher magnification essential for Planetary imaging.

Shot noise is associated with the uncertainty of measuring anything with a CCD Camera.
Here, Steve Chambers takes a closer look at its relationship with signal to noise ratios, and what we can do to control it in our images.

So what is Servicing and Hypertuning?
Equatorial Mounts and Alt-Azimuth are precision made tracking devices made to follow the procession of the night sky. However, most mounts are assembled on a production line and therefore their performance and build quality is defined to a mean value of performance versus build time efficiency. Simply put, there is room for improvement.
More modern EQ mounts like the newer iOptron CEM25/iEQ30/45-PRO and their CEM-60 provide less headroom for improvement due to the technologies they incorporate and better build, nor would it be viable as they have not been on the market long enough in any real number.
The International Space Station, traveling at over 17,000 mph (27,300 kph), to cross the face of the Full Moon. Only about a half second! To see it with your own eyes, you need to know exactly when and where to look. Full Moon is best, since it’s the biggest the moon can appear, but anything from a half-moon up and up will do.
The photo above was made by superimposing 13 separate images of the ISS passing in front of the Moon into one. Once the team knew when the pass would happen, they used a digital camera to fire a burst of exposures, capturing multiple moments of the silhouetted spacecraft.

Wow! If you’ve ever wanted to know what it would be like to hang above Jupiter’s clouds, here you go. This absolutely stunning view of Jupiter’s northern latitudes shows incredible detail of gas giant’s swirling cloudtops. And it features, in the lower left in the image below, the storm on the gas planet known as NN-LRS-1, or more colloquially, the Little Red Spot.
EAGLE OBSERVATORY is the most powerful control unit for astrophotography based on an i5 Dual Core 2.3 GHz (with Turbo Mode up to 2.9 GHz) and 16 GB of fast RAM that, due to the increased storage space ( SSD 128 GB) and the ignition is switched off and the remote control devices, allows you to control and feed even the larger tools such as those installed in the observatories. All in a lightweight, compact and designed to be installed IN your telescope!
The Celestron EdgeHD 925 is an aplanatic astrograph lightweight and compact. Compared to 200mm model in diameter, on visual observations it generates brighter and more detailed images. In photography it's excellent, especially for those who want to devote himself to high resolution photography of the planets and the moon, where it excels thanks to the special optical design with the two mirrors to a focal ratio slightly longer than the other EdgeHD.
The Sigma 14mm 1.8 DG HSM Art is the worlds first 1.8 prime lens at the 14mm focal length. This fast wide prime features the same large aspherical element touted in the Sigma 12-24mm F4 Art to control distortion and create stunning imagery. An updated Hyper Sonic Motor (HSM) provides fast and accurate autofocus while 3 Premium FLD and 4 SLD glass elements control chromatic aberration and sagittal comma flare.
APT stands for "AstroPhotography Tool" and it is like Swiss army knife for your astro imaging sessions. No matter what camera you use - Canon EOS DSLR or CCD, APT has the right tool for planning, collimating, aligning, focusing, framing, controlling, imaging, synchronizing, analyzing and monitoring. All its features are packed in an easy and comfortable to use interface with design that had no alternative back in 2009 when it was released. Since then APT is constantly being improved and refined by the real experience of many astro photographers from all over the world and by author's own experience. Currently APT works on MS Windows XP, 7, 8, 8.1 and 10.
We live in a very special time, one in which science has provided an emerging understanding of how earth and the universe came to be. The road to this knowledge was paved with 175 years of astronomical images acquired by the coupling of two revolutionary technologies.....the camera and telescope. With ingenuity and determination humanity would embrace these technologies to tell the story of the cosmos and unravel its mysteries.
DSW is a remote astrophotography observatory situated on Glorieta Mesa in Rowe, New Mexico. This high altitude site (elevation 7,400 feet) offers pristine dark skies, transparency, excellent seeing, and weather conditions coveted by all imagers. We make remote imaging and hosting affordable for the “average” backyard astrophotographer by offering exceptional value and promoting teamwork.
We’ve spent the last several weeks setting you up with a telescope, mount, camera, and guide system. Now it is finally time to get outside with all that gear (assuming you, unlike me, have clear skies)
Markarian’s Chain is an impressive photography subject for those with a camera and telescope to capture it. This string of 7 distinct galaxies is a member of the Virgo Cluster.
A few weeks ago we announced that we’re working on a new cooled CMOS camera for astrophotography. While we continue working towards a release date, we thought it a good time to start taking a look at some of the differences between CCD and CMOS sensors.
