NOTE: The recommended solar filter for this scope for solar observing is the Astrozap Glass Solar Filter (Product No. 124451) 

• 6” (150mm) f/10 Schmidt-Cassegrain includes StarBright XLT coatings for better light transmission
• The most compact and portable of Celestron’s German equatorial mounts offers the same rigidity as our larger mounts with minimal flexure and an improved industrial design
• Holds a maximum instrument capacity of 30 lb
• Every feature an astroimager wants: PEC, an autoguider port, the ability to image across the meridian, and more
• Dual saddle plate is compatible with narrow CG-5 dovetails and wider CGE dovetail. Also compatible with Vixen format dovetails longer than 100mm, but not compatible with Losmandy D format plates.
• Latitude range allows the mount to perform between 7° and 77° latitude
• Accessories include a 25mm eyepiece, 1.25” star diagonal and 6x30 finderscope

The 6” Schmidt-Cassegrain optical tube offers 40% more light gathering ability than a 5” telescope. The Schmidt-Cassegrain design also eliminates chromatic aberration, making it a good choice for entry-level astroimaging.

NOTE: The recommended solar filters for this scope for solar observing are;

- the Orion 185 mm (7.17") Glass Solar Filter (Product No. 125081) or

- the Meade Glass White Light Solar Filter 172 - 180 mm (Product No. 125918).
