Product Description

The TS-Optics APO refractor telescope 65Q is a high end telescope and tele lens that is equally suited for astro imaging and nature photography. With its excellent optical design it also doubles as a compact travel scope / spotting scope for demanding visual observing.

The TS Quadruplet Astrograph 65mm f/6.5 offers a highly corrected focal plane for photography and is therefore a very attractive alternative to the Takahashi FS-60 or the Pentax 75 SDHF, as well as very expensive telephoto lenses available from the renowned camera manufacturers. It is beautifully made and ideally suited for mobile imaging featuring a minimum mechanical length of 340 mm (with retracted dew cap). Image quality on- and off axis is perfect and the very low chromatic abberation allows a visual magnification range up to 150x

2" RP focuser
This focuser combines the advantages of a rack & pinion focuser with an improved bearing system. A Crayford design has its optimal stiffness only when the drive shaft is pressed firmly against the drawtube - this causes bucky operation. The focuser of the 65Q avoids this problem while still offering movement free of image shift. The fine machined cograil allows smooth focusing even under heavy loads up to 3 kg.The focuser has a 2" and 1.25" adaptation with brass compression rings. 2" accessories are locked by two thumbscrews - this prevents tilting

Technical details:
-- Aperture: 65mm
-- Focal length: 420mm
-- Photographic speed: f/6.5
-- Diameter of the corrected field: 44mm
-- Weight: approx 2.8 kgs (with tube rings and prism rail)
-- Focuser: 2" RP with improved bearing, 360° rotation and ring clamping
-- Mechanical length: 340/375 mm with retracted/extended dew cap
-- Resolution: 1.78 arc seconds
-- Limiting visual stellar magnitude: 11m6

no mount is included

This is a brilliant astrograph. Flat field, clear images and snappy focus that makes photography of extended objects simple and enjoyable. This review shouldn't need to cover this. The specifications alone mean it is brilliant at that job.

It is solidly built - very solidly built - a good heft and the focuser can easily take the weight of a 60Da. There is no weak component that I feel may break.

I bought this as an astrograph for wide field nebula photography, but, having become a father I found I didn't have the time for astro photography. I found I suddenly needed a scope I could pull out, mount on a solid photo tripod and video head, and get observing quickly. All my other scopes require levelling, alignment and power supplies.

Enter the APO.

This delivers quality observing in bucket loads. Under good conditions, using a good eyepiece and a high quality Barlow, magnifications beyond 130x are not just possible, but usable (eg with TeleVue PowerMate 2.5x and Baader Hyperion 8mm/5mm). Deep detail in lunar craters is sharp and contrasty, multiple cloud bands on Jupiter (not just NEB & SEB) are clearly visible. Saturn is an incredible sight. This is better than my 150mm Mak for planetary observing.

To do this scope justice for visual observing, don't use a plain aluminium diagonal, get a dielectric diagonal. Also invest in some decent eyepieces - don't use cheap ones.

Pros:
Solid as a rock
This matches and beats the optical quality of my best eyepieces

Cons:
Focuser doesn't have enough travel to use a TeleVue PowerMate and DSLR - you need a 50mm or 80mm 2" extension tube. It has enough travel for an eyepiece, standard Barlow & DSLR, standard Barlow & eyepiece and PowerMate & eyepiece - just the PowerMate & DSLR optical combination has a further focus point.
