1. Introduction

Welcome to my equipment page. Below are the details for the main equipment I use for astronomy & astrophotography. I also point you to comparable equipment available at:

2. My Telescope

The telescope I use is an 8" Celestron Schmidt Cassegrain Telescope (SCT). Here's the details:

Mount: CG5
Aperture: 8" (200 mm)
Focal Ratio: f/10
Focal Length: 2000 mm
Highest Useful Magnification: 450X
Resolution: .57 arc/sec
Home-built pier

See my telescope optics calculations page here.

Further Resources

This is the enhanced version of my Celestron telescope. It features NexStar® computer-control technology and Autoguider port for long-exposure astrophotography. Check it out at telescopes.com.

See my article: Webcam Astrophotography Tutorial for Planets.

The Philips ToUcam Pro is a very popular camera for astrophotography. However, Celestron has their own version as well. And, it is designed specifically for Astrophotography. See below. Also, be sure to visit my astrophotography cameras page to see a large variety of astrophotography cameras.

4. Viewfinders

Celestron 6X30

TELRAD

More about the TELRAD

The Telrad viewfinder is one of the best gadgets I have purchased for my telescope. I had used them before at star parties, and wanted one for myself. Well, it was worth it! I hardly use the 6X30 finderscope anymore. The Telrad makes it easy to find celestial objects because it's not magnified and is correctly oriented. The TELRAD projects three red rings spaced at 4 degrees, 2 degrees, and 1/2 degree in diameter. These rings are used to "starhop" to objects. See more details at telescopes.com.

5. Focuser

JMI NGF Zero Image-Shift Microfocuser

This was the final gadget that allowed me to do astrophotography from inside. I watch the object on the computer screen and make fine adjustments to the focus without being at the telescope! See my remote astrophotography setup page here.

5. DC Motor Drives

RA Motor Drive

DEC Motor Drive

I added the dual axis motor drives to my telescope about a year after I bought it. It's a must for astrophotography and for controlling my telescope from inside.

5. Home-Built Pier

I designed and built this pier to be a solid platform for astrophotography. I contains the following features:

Adjustable platform for precise leveling of the CG5 mount
Solid 4x4 legs (4 legs in concrete)
4x4 center post in concrete
Eyepiece and gadget holder
Utility box with jacks for microfocuser, camera, and motor drives control.
Schedule 40 conduit for cabling to control room in garage
