Sharpstar 2" Triplet 0.95x Reducer / Coma Corrector for f/3-f/6 Newtonian Reflectors with M48 Thread
Sharpstar 2" 0.95× coma corrector can be applied to most marketable Newtonian reflective astrographs. It’s of high quality and easy to use. Sharpstar 2" 0.95× coma corrector is designed for APS-C imaging circles(28mm), suitable for Newtonian reflectors with focal ratio between f/3 and f/6, and aperture size from 150mm to 600mm. The reduction factor is 0.95×, thus it can reduce the original f/4, f/5 and f/6 respectively to f/3.8, f/4.75 and f/5.7, effectively shortening the exposure time. Besides, it can improve the star shapes. The diameter of stars in the center of the field can be limited within 10um.

This is an original replacement counterweight shaft (w/o CW safety screw) and the extension bar for the iEQ45 Pro/iEQ45. This is also the extension bar for the CEM40/60/70 GEM45 mounts. Attach to the CW shaft and will create more counterbalance torque.
Can be used to connect Sony NEX lens and ASI cameras with small sensor formats, such as ASI1600, ASI294, ASI183, ASI174, ASI432 and ASI585. Only support manual lenses supported, not compatible with automatic lenses.
E-mount lenses with 18.5mm back focus length are supported (Only manual lenses).
As absolutely beginners in stargazing my daughter and I find this 32mm eyepiece very valuable for the eyepiece collection. We have a 10, 15 and 25mm and a barlov already and it was time to look a bit wider in the sky. The GSO 32 does the job well. And as always the good service from Thaiexcite is appreciated.
