#10 inch newtonian telescope upgrade#

The telescope has a metal tube, which is strong and offers good stiffness in order to assist collimation retention. The secondary spider is thin enough to minimise defraction spikes, but substantial enough to support the secondard mirror assembly well. This primary mirror is ably mounted in a newly-designed cell with 9-point floating supports, which retains collimation well and is very simple to adjust. The main mirror is made of H-PZ33 low expansion glass, in order to minimise cool down time.

#10 inch newtonian telescope upgrade#

A 10' telescope offers an upgrade from an 8' of nearly 50% extra light gathering power, meaning brighter images, better resolution and greater colour saturation. This model is the largest aperture in the range. A Dobsonian telescope offers the best value for money in terms of telescope purchase combining large apertures and ease of use, and the Bresser Messier 10 inch Dobsonian delivers this and more. Large aperture optics in an easy to use system that can be ready to use in moments to take advantage of any observing opportunity.
