365ASTRONOMY TESTING PROCEDURES
We would usually test about 30 - 60% of the arriving Sharpstar and Askar telescopes (except the smallest ones in the FMA and ACL range). This will provide us with a good understanding of the quality of that batch of optics. We would also test the focuser and check the optical tube, tube rings and dovetail bar and accessories for any visible damage or fault and take a series of test images with a full frame DSLR camera of a specially designed test chart that will show whether the telescope is fit for a full frame sensor or not, whether the image is flat in all corners and generally it will indicate the quality of the optics, i.e. resolution. Whilst we do store this information for all tested telescopes, we don't usually include a printed report, but if you ask, we might be able to send it to you). If we find that the optics are not correctly collimated then we will send them to a specialist to correct it or if the optics cannot be corrected to a good performance then those will be sent back to the manufacturer for replacement, although our experience with Sharpstar and Asker telescopes is quite good, we rarely had to do that. We believe that there is no need to offer complicated optical test reports that would assume a degree in optical sciences from the user to fully understand them.
The SharpStar 61EDPH refracting telescope is a three-element fully separated design that includes one exotic ED lens (ultra-low dispersion ED glass) and multi-layer coating on all surfaces to reduce internal reflections.
The SharpStar 61EDPH provides an impressive focusing system combined with an excellent optical system. The SharpStar 61EDPH has a high load dual-speed 2.5-inch rack and pinion focuser with a 1:10 aspect ratio compared to many refractors on the market that use a toothless focuser (i.e. Crayford). Rack and pinion focusers can bear a higher load due to their construction, so you don't have to worry about wobbling or loosing focus when using heavy-duty observation accessories or a heavy camera. In addition, the 360-degree rotator allows you to easily rotate the camera to achieve the best image framing. The 2-inch eyepiece holder barrel features a brass compression ring, so that you won't scratch your accessories.
The SharpStar 61EDPH is a reasonably priced observational or imaging tool with fast-focus ratio that features exotic super ED glass, high quality heavy duty 2.5-inch rack and pinion focuser; when compared to other similar products on the market, its value is self-evident.
In addition, the 61EDPH can be equipped with our dedicated 2.3-inch field flattener for FULL FRAME astrophotography, which provides excellent image quality and avoids field edge star distortion.
