About this product
Sharpstar 50 EDPH APO Triplet Refractor
This compact 50mm f/5.5 APO refractor telescope has triplet air-spaced APO optics, including two pieces of ED glass. Triplet optics are rare in a telescope this size.
An optional 0.84x Reducer is also available that converts the 50 EDPH into a highly portable astrograph.
The 0.84x reducer reduces the focal ratio to f/4.6, provides excellent field flattening capabilities, and supports sensors up to APS-C size. The reducer also has an M48 adapter and a built-in M48*0.75 2" filter thread for direct filter mounting.
The rear of the Sharpstar 50EDPH is equipped with a 1.25" adapter, which can be used with a 1.25" diagonal and eyepiece for rich field visual astronomy. When used this way, it provides beautifully sharp views of The Moon and the Galilean Moons and main cloud belts of Jupiter, Saturn's rings, etc.
With a body length of 196mm and weighing only 1kg, it easily fits into a backpack or airline carry-on luggage. The retractable lens hood shortens the overall length further and increases portability.
The compact size makes it an excellent telescope for use with portable astronomy mounts, such as the Sky-Watcher Star Adventurer GTi.
Other features include a 70mm Vixen-style dovetail plate with slotted 1/4-20 threaded holes, making it easy to adapt to most equatorial mounts and be mounted on a photo tripod.
The sturdy dual-speed rack and pinion focuser, with a 1:10 precision fine adjustment knob, have a travel length of 60mm.
A 360°rotator with a locking screw is located before the focuser.
The Sharpstar 50EDPH also includes two 5cm M48 extension tubes. The extension tubes can be connected to the eyepiece for direct visual observation instead of the diagonal or to a planetary camera for planetary imaging.

Nice telescope with a serious design flaw 28 April 2024 | Geir
I bought this telescope late last year , and it.looks like the build quality is great , however it has a very serious design flaw , a flaw that has made me not wanting to try it before it's been fixed.
The flaw is that the mounting foot is fastened with 2 tiny 3mm screws , that goes in aprox. 3mm into the telescope ring , and there has been reports of them loosening.
One crashed down also.
Sharpstar says they are working on it , but who knows , but hopefully they will come up with a sollution for those of us that have bought it.
I haven't dared to use mine yet , but i have ordered tube rings and dovetails to make it safe.
I have given 3 stars since the build quality seems good (apart from the flaw) , and i wouldn't be worried buying from Flo , since they always stands behind their products.
Here ise the thread on Cloudy nights regarding this telescope and flaw: https://www.cloudynights.com/topic/908013-sharpstar-50edph-unboxing-and-initial-impressions/
Response:
SharpStar have contacted us about a solution for this - they are changing the design of the foot and will be supplying a cradle replacement for existing customers shortly - we will be in touch to arrange this with you.
Ongoing, any new sales will include the updated cradle and we will update our website soon to show this.
