“Compared to our own 250mm f/5 Newtonian reflector, the extra light gathered by the Explorer-300P was obvious. We got impressive views of a wide range of celestial objects. Galaxies such as M65 & M66 in Leo were wonderful, with strong hints of subtle detail along their spiral discs. The nearby galaxy NGC 3628 also stood out well. Nebulae shone against the background sky. M1, the Crab Nebula, showed varying degrees of mottling and scalloped edges – very satisfying indeed. The Orion Nebula, M42-43, was awash with nebulosity and we found we could easily get lost amongst the detail.. At its centre, the Trapezium group of stars sparkled and, at the highest magnifications , we spotted several of its fainter mag. +10 stars, even though the atmosphere wasn’t as steady as we would have liked for such high-magnification views. Detail Explosion: Late into the night we selected the globular cluster M13 from the hand-controller. As it swung into the field of view it was breathtaking, with swarms of stars looking like bees around a honey pot. The view was so good that we noticed a dark feature, commonly known as the Propeller, superimposed on one side of the cluster. It was easily the best view of the cluster we’ve ever had….For crystal clear views of deep space, this is hard to beat!”

Better field correction with the Sky-Watcher Coma Corrector:
Due to physical reasons, a fast newtonian system produces coma outside the optical axis. The Sky-Watcher Coma Corrector compensates for this effect and leads to pinpoint stars across the field of view. It works for both observation and astro photography.
Sky-Watcher AZ-EQ6 SynScanThe Sky-Watcher AZ-EQ6 SynScan gives optimal stability and pointing
accuracy for a wide variety of heavy professional photo and video
equipments. It is a hybrid mount with alt-azimuth capability for general use, and equatorial capability for astrophotography use. Supplied
with a SynScan handset with dual AZ/EQ firmware, it can automatically
find and track over 42,900 celestrial objects from its database.
AZ-EQ6 SynScan is capable of carrying heavy-duty photographic equipments for professional shooting and video recording. It allows accurate repeatable pointing on 6 programmable targets and is a very efficient transportable mount weighing only 15 kg, for a load capacity of 20 kg (counterweight excluded).
An excellent
feature of the AZ-EQ6 SynScan is the patented dual-encoder technology.
This technology allows the telescope to be moved manually either axis
without the mount losing its positional information which gives enormous
freedom and convenience for users.
New Features:
♦ Germen Equitorial / Alt-Az dual mode
♦ Permanent period error correction(PPEC). PPEC can be trained with Autoguider or PC.
♦ Belt drive - Super smooth PE curve. Low backlash, silent slewing.
♦ Shutter release control for batch exposures of astrophotography.
♦ Motor controller with high torque and accuracy.
♦ Include two dual-fit (45mm/75mm) saddle for mounting two telescopes.
♦ Improved reliable power supply outlet.
♦ New motor controller with higher torque and accuracy.
♦
Polar-alignment with polar-scope or SynScan HC's polar-alignment
routine. (Other dual mode mounts in the market do not have a polar
scope.)
♦
Primary axis encoder tracks the mount's position. Usera can push the
mount at any time without worrying about loosing the mount's alignment.
Includes:
Two Dual-fit Saddles
Two 5kg counterweights
Note: Baader filter and solar finder must be used during all sun observations to avoid damage to your eyes.
Tracking Accuracy: 0.1436 arc minutes
DSLR Electronic SHutter RElease Port : Yes
Autoguider Port: Yes
PEC control in EQ mode
Polar Alginment : via software control or supplied polar scope
Alignment methods: 1, 2, or 3 star alignment (EQ) / brightest star or 2 star alignment (AZ)
Telescope Connection: 2 x dual-fit saddle plates supplied accepting 45mm & 75mm dovetail bars
RA/DEC Worm Gears: D=92.5mm, 180 teeth, brass
RA/DEC Axes: D=40mm, steel
Latitude Adjustment Rage: 10o to 70o, 90o
Azimuth Adjustment Range: About ± 9o
