Solar Eclipse

Posted by Paul On August - 21 - 2017

8-21-2017

Here are some of the photos I took today of the solar eclipse; since I stayed home in Provo I was only able to record a 90% coverage of the sun.  Still it was very cool.  When the sun was 90% covered the temperature had dropped about 15 degrees and it was really pleasant outside.  The photos were taken with my Celestron 11 inch Schmidt Cassigrain telescope with a focal reducer attached.  The focal reducer caused the images to be clipped – that's why I wasn't able to record full pictures of the Sun.  The camera I used was a Canon 60Da camera modified for astrophotography.  The pictures were taken at an ISO of 200, exposure of 1/200 second.  I didn't order a sun filter ahead of time for the telescope, so I made one using 2 layers of a space blanket which worked ok.  It may have caused some degradation of picture sharpness however.

10Micron Telescope Mount

Posted by Paul On January - 8 - 2016

In  November I received my new telescope tripod and mount.  It's made in Italy by 10Micron and it's the GM1000HPS model.  

10 Micron are one the highest regarded manufacturers of high precision ultra high quality mountings in the business.

The GM1000 HPS features:

Absolute on-axis encoders in RA & Dec, featuring
more than 10 million increments (interpolated),
fully encapsulated and calibrated

Provides up to 0.5“ RMS tracking accuracy – for long duration UNGUIDED imaging – even at long focal lengths

Closed loop (encoder controlled) satellite
tracking

speed – up to 15°/s

and much much more!

Here are some photos:

The boxes were heavy!

Now I've attached the Celestron 11 inch telescope, the focal reducer, the Moonlite focuser and the Canon 60Da camera._DSC2535 _DSC2536

I have since removed the on axis guide camera as it's not needed with this mount._DSC2537 _DSC2538 _DSC2539 _DSC2540 _DSC2541 _DSC2542 _DSC2543 _DSC2544 _DSC2545 _DSC2546 _DSC2547 _DSC2548 _DSC2549
