The thickness of the M42M-M48F 22.5mm extender is 22.5mm. It is an important astronomical accessory for ASI2600MM Pro users who want to connect the camera to 7x36mm filter wheel to reach 55mm back focus distance while without the involvement of OAG-L.
Connection Guide:
When connecting the ASI2600 to 36mm EFW, you need to screw off the sensor tilt plate coming with the camera first, then use the screws to fix them. This can help you get the distance between the filter and the sensor much closer.
Refinded Design · Anti Light-Leak Protection · Built for Astrophotography A re-engineered internal design helps reduce light leakage, while the refined mechanics deliver smoother, more consistent rotation.
The exterior has been subtly streamlined, giving the wheel a cleaner and more cohesive look. Nothing dramatic. Just better in the ways that matter — so your imaging workflow stays steady, reliable, and quietly improved.

กล้องดูดาว Sharpstar 76mm 76EDPH f/5.5 ED Triplet Apo Refractor Telescope สีแดง
Sharpstar has been making refractors for many years for well-known worldwide astronomy vendors, and they’re now marketing their own premium apochromatic refractors at a surprisingly affordable price. The Sharpstar 76EDPH is the second in their series of instruments under the Sharpstar brand that’s quickly gaining a reputation for precision instruments for visual observation and astrophotography.
80PHQ inherits the optical design of the PHQ family, adopting a 3+1 quadruplet lens structure which contains two pieces of ED glass that can effectively reduce chromatic aberration and enhance clarity and sharpness. It’s worth mentioning that all astrographs from the PHQ family come with an integrated lens combination rather than simply placing three major lenses and a corrector together in a line. In other words, the whole optical system cannot solely perform without any piece of these lenses. This structure design leads to a more rational lens arrangement, better vignette control and superior image quality. The focal ratio of 80PHQ is f/7.5. It’s a “long” focal-ratio astrograph compared with other counterparts from Askar. It’s a little bit longer even compared with 107PHQ which is f/7 in focal ratio.
A superb eyepiece that came with my 10 inch GSO telescope, it gives you wonderful views of The Pleiades etc. and other night sky wonders, it is an excellent eyepiece in my opinion.
