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.
