Description
Not every serious astrophotography refractor needs a 20kg mount. The Artesky ED 102/714 pairs a 102mm ED doublet with a fully rotatable 2.5-inch focuser in a tube weighing just 4.3kg, needing only 7kg of mount capacity — the most accessible entry point into astrophotography-capable refractors in this catalog.
This Ohara FPL-51 doublet won’t match the color correction of an SD or triplet design at higher magnification, and that’s a fair trade for the weight and price here. What it does deliver is a genuinely portable APO refractor good for lunar detail and medium-field astrophotography with a modern dedicated CMOS camera, without the observatory-grade mount the larger APM tubes in this catalog require.
Key Features of Artesky ED 102/714 OTA Refractor Telescope
A 2-element air-spaced ED doublet with Ohara FPL-51 glass keeps this refractor’s optical formula simple, light, and genuinely portable.
- 2.5-inch rack-and-pinion focuser rotates a full 360 degrees for precise camera framing
- At 4.3kg, this is the lightest refractor OTA in this catalog, easy to hand-carry to a dark site
- Only a 7kg mount requirement opens this up to lighter alt-azimuth and equatorial setups
- 33mm image circle is optimized for APS-C format cameras, a common entry point for astrophotography
- Fully multi-coated broadband optics keep contrast high on lunar and planetary targets
- Standard finder shoe accepts a red dot or optical finder of your choice
- 2-inch to 1.25-inch reducer adapter ships included for eyepiece and camera flexibility
- Magnification range from 15x to 200x covers casual lunar viewing through closer planetary looks
Where the Artesky ED 102/714 Pulls Ahead
Against APM’s SD and triplet refractors in this catalog, the Artesky trades ultimate color correction for a tube less than half the weight and a mount requirement a fraction of the size, at 7kg versus 15kg or more. For an observer without a heavy-duty equatorial mount already in place, that difference decides whether this hobby starts this year or waits for a bigger budget.
