JMI Sky Trekker 400 Wheeley Bar — Extra-Large Dobsonian Telescope Dolly

The JMI Sky Trekker 400 Wheeley Bar is the largest member of the Sky Trekker Dobsonian dolly family — designed for the biggest Dobsonians in the 18-inch and larger class. Roll the rocker box of your large-aperture Dob from storage to your dark-sky site or backyard pad without lifting. On sale — was $899, now $599. Made in California, USA.

Product Overview

The Sky Trekker 400 cradles the base of very large Dobsonian rocker boxes and rolls on heavy-duty locking wheels. It is the correct Dobsonian dolly for Dobs with apertures in the 18-inch range and above, where the rocker box is simply too heavy to carry in and out for each session.

Who Is This Product Best For?

Owners of very large Dobsonians — 18-inch class and above — where the rocker box weight makes manual carry impractical. Also well-suited for large-aperture Dobs at permanent or semi-permanent dark-sky observing sites.

Our Recommendation

The Sky Trekker 400 is built for the largest Dobsonians where the rocker box weight makes hand-carrying impractical. If your Dob is in the 14-inch to 16-inch range, check the Sky Trekker 350 instead. The current sale price makes this excellent value for any serious large-Dob owner.
