Customer Reviews
I got this a couple of weeks ago and the results from this paired with ZWO ASI585 MC Pro are just amazing. I am using this with a guiding setup, Star Adventurer GTI and an ASIAirPlus. This is my 1st scope but the final edited images coming out of this are easily comparable with the more expensive scopes like Redcat51 maybe. Just get the 0.84x reducer with it to get a 227mm focal length and an a ZWO EAF for autofocusing. You would be set for some amazing results. Service from AllStar team has been great.
An amazing tiny telescope fit for travelling!
Actually purchased this 50 mm triplet for a grab n go visual instrument and the optics live up to the name sharpstar ! The moon, Jupiter and Saturn using the televue 3-6 mm zoom were excellently detailed for a 50 mm , greenish Orion Nebula with the trapezium bluish stars were a treat as well as many double stars and bright deep sky objects of the winter sky , love my little gem !
