300MM F/6 MCDK ASTROGRAPH V2 BY JTWASTRONOMY

astrograph

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. While there are several small aperture apochromatic telescopes available at comparable prices, they often significantly fall short in one department or another.

The Explore Scientific Essential Series ED80 (model # ES-ED0806-01) delivers the goods with solid construction and great optics. It has a few shortcomings and compromises that keep its price affordable, but overall, this fine instrument will fulfil the needs of the most demanding photographer without breaking the bank in the process.

Dobsonian Astrophotography

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 in CCD Cameras

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. However, older platforms like Sky-Watcher, Celestron and Meade can be serviced and modified to provide substantially improved performance, sometimes down to sub-arcsecond guiding via PHD.

HOW TO SEE THE SPACE STATION FLY IN FRONT OF THE MOON

ISS-transits-crescent-moon-David-Duarte-UT

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.

JUNO JUST TOOK ONE OF THE BEST IMAGES OF JUPITER EVER

by Nancy Atkinson

 

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.

PRIMALUCE

EAGLE OBSERVATORY - Control unit for observers

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!

2015V2_170204_1200

Comet C / 2015 V2 (Johnson) photographed on February 4, 2017, is already four months after reaching its perihelion and with a magnitude of 10.5. Its dense tail of dust has a length of 12 minutes of arc, while the image clearly shows around its head a gaseous outer comma of green color of 5 minutes of arc that correspond to a sphere of 350,000 km of diameter.

PRIMALUCE celestron_tubo_ottico_edgehd_925_losmandy

Celestron EdgeHD 925 with Losmandy bar

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. In this the user will get a better optical correction and a higher contrast of the images.

 

 

The difference in price is justified not only by the larger diameter but also for the higher quality standard accessories, such as the eyepiece Luminos 23mm ideal for deep-sky viewing Wide Field and diagonal 50.8 mm in diameter ( which also accepts eyepieces 31.8 mm).
