The Skywatcher Quattro series are premium quality imaging Newtonians with a wide field of illumination and fast f4 focal-ratios.

8-inch and 10-inch models are available with steel or carbon fibre tubes. Tube interiors have knife-edge ray traced baffles.
CARBON FIBRE TUBE: Carbon fibre is a strong and lightweight material with better thermal stability than steel. This is especially important for astro-photographers dealing with long exposure times. Imaging telescopes made of less thermally stable material can deviate from optimum focus after long time exposures. With a carbon fibre tube, it can remain in focus for a longer period of time.

2" DUAL-SPEED LINEAR POWER FOCUSER: The new linear power focuser moves the drawtube using rollers rather than a rack and pinion for smooth precise focus adjustment. The dual-speed feature has a second focus knob with a 10:1 speed reduction for super-fine adjustments. The focuser is perfectly adequate but in our humble opinion the telescope deserves something better. If you agree check out our Moonlite or Starlight Instruments focusers :-)

PYREX MIRRORS: All models feature paraboloidal primary mirrors made of low thermal expansion Pyrex glass resulting in shorter cool-down times.

"The Quattro's tube is lined with a set of nine internal baffle rings. Their main purpose is to cut down on stray light entering the telescope tube, helping to improve image contrast, but they also lend a bit of extra stability to the tube structure....The Quattro-8S is fitted with a Crayford-style focuser that performed well. It has tension adjustment, focus-lock and a 10:1 dual-speed fine focusing option, and also comes with a 2-inch fitting that has a T-thread on its external side. This allows a good connection to be made between scope and camera with the right adaptor ring....Visually, the Pleiades looked like diamonds hanging in space, with a hint of nebulosity visible around the brightest star Merope. The stars were generally crisp and sharp, with good colour on show. The scope is superb for imaging too, delivering shots that appeared to have higher contrast than the other scopes on test."

Excellent Imaging Scope
Tuesday, 29 December 2015  | 

The Skywatcher Quattro 10" F/4 CF is a good looking scope. The white tube rings, end trims and focuser contrast strikingly with the shiny black carbon fibrer tube, and exude an air of quality. It looks well made and solid and is in fact pretty heavy considering the tube is carbon fibre. Compared to my 8" F/4.5 which has a steel tube this 10" F/4 is double the weight and bulk. At 14kg it's way too heavy for my EQ5 mount but works well on my EQ6. I have read reports that the focusser could be better. Maybe it could but to be honest I find it perfectly adequate. It holds my large format camera solidly in place and the dual speed control makes finding perfect focus remarkably easy. If I have any complaints it's that the finder scope could be better. It doesnt seem to be held firmly enough on its mounting bracket and it would be nice if it had been a right angled model. The tube end cap has a couple of 50mm diameter apertures in it that can be opened up to form a rudimentary hartman mask to aid focussing, A nice example of the thought that has gone into making this scope more suited to imaging.
The scope arrived with the collimation just slightly off but this was soon rectified with the use of a laser collimator. Incidentally the user manual makes no mention of how to undertake collimation - not a problem for me but could be a bit perplexing for a novice. The push pull knobs that adjust the primary mirror cell are really easy to use and look smart too.
First night under the stars and there was an 8 day old moon in the sky so I made this my first target. A short focus newtonian such as this would not normally be the preferred instrument for luna observation and photography but I have to say I was very impressed with the Quatro's performance. Visually it was the equal of my 7" Mak and way better than my 14" SCT. I made several images at prime focus with a Baader Coma corrector and I have to say they are some of the most detailed whole disc views of the moon I have ever taken. They far surpassed anything I have taken through the Mak or the SCT, and had a nociceable edge over my 8" reflector and 6" refractor. Camera used was a 36 MP full frame DSLR at ISO 100.
I have yet to fully exploit the Quatro's capabilities on deep sky objects due to persistant bad weather, but I can say that visually the view is sharp and contrasty. Photographically using a coma corrector (which you really do need at this fast focal ratio) stars are well shaped across the field of a full frame DSLR, although there is some light fall off towards the field edge but this can easily be corrected in post processing. The nebulosity in the Pleiades starts to record in just 5 seconds at ISO 6400 and the 1000mm focal length is ideal for framing this cluster, as it is for objects such as the Double Cluster, the Sword of Orion, the Rossette Nebula, M33 and many more.
I am really pleased with the 10" Quattro CF and it has now become my instrument of choice for deep sky photography. I can highly recommend it.
