Information: Typical Power System for a Truss Tube Dob Telescope (block diagram)[click this line]


We now are into our 11th year of producing and selling online accessories for Obsession Telescopes and other Big Dobs! This is the home of the original DSC Stalk! The website is often updated with appearance and content changes, so check back often for new additions.

Scroll down this page for an index of Accessory Products and Services.   The accessories you see primarily are enabling accessories; i.e., they either make setup and tear down easier, or they make the observing experience more enjoyable or efficient, or both.   Our products make the interface smoother between telescope and eyepieces, dew control systems, cameras, digital setting circles, and go to systems!

Services include ServoCAT installation , Ground Board Repair, and Glatter Sling Installation.   We have installed ServoCATs on Obsession classics and Obsession UCs, as well on Starmasters, Discoverys, TScopes, and homebuilts!

We have outfitted many Obsession UC15s, 18s, and 22s.   See our UC page for Markless Astronomics accessories that fit the UC! (click here).

Feel free to e-mail me with questions about products, shipping, how-tos, etc.   I respond to e-mail continuously, often within minutes of when it is received.   I can also accept your telephone call.   E-mail me privately for the number to call.   Want a custom accessory built?   Contact me and let's discuss it.

Ordering Process:   Email me with selected items identified.   I will respond with a total cost and payment options.   S&H costs depend on location.   Multiple item orders result in lowest S&H.   Additional information (e.g., telescope size, equipment installed, etc.) often is needed.   Write for assistance at any time.

Unfortunately in these unsettled economic times, prices and shipping costs are subject to change at any time without notice. So, write for the latest pricing.
