About this product

Model:  skywatcher-CQ350-pro-head
Part Number:  20309

NEW Sky-Watcher CQ350 PRO Go-To equatorial mount with centre-balanced and claimed 35 kg payload for astro-photography, excluding counterweights.

The CQ350 PRO' payload capacity places it neatly between the Sky-Watcher EQ6-R PRO and EQ8-R PRO.

The dual-fit 45mm/75mm saddle supports Vixen-type and Losmandy-type dovetails so can be used with a wide range of OTAs and peripheral equipment.

With high-precision belt-driven stepper motors on both axes, movements are smooth and quiet.

Supplied with a Synscan computerised handset with 42,900 object database and two 10kg counterweights.

An optional external polarscope is available as an accessory.

Tripod is not included but two are available: the 20293 Pier Tripod for EQ8 (CQ350 has the same hole spec'/spacing as EQ8) and a new tripod with 2.75" stainless pipe legs.

Just WOW the CQ350
26 January 2024  | 

Had the Cq350 a few weeks but needed to raise the pillar and the weather has been awful. Anyway, this is a beefy mount but manageable I would imagine if you were setting up each night/day. Mine is observatory mounted so no problem. This is used for solar observations and imaging. The dec hub works well powering my focuser's and zwo cameras. I have double mounted lunt HA, DS and bresser Cak. I'll add the triple scope in the spring. This mount is spot on even unguided for several minutes. This is long enough for solar as I don't need to guide. It's responsive in both dec and ra and from what I can tell, no backlash. I would even dare to say it's slightly better than my Eq8 R Pro that I use for night time in my other observatory. Highly recommend this mount and of course FLO.

Beautiful mount

The mount is excellent, guiding is great for the most part around 0.6-0.8rms though itís been as low as 0.2-0.4. Amazing service from First Light Optics. They are the benchmark to what all online retailers should be. You can buy with confidence. I had considered returning this mount because itís a monster but I stuck with it.
