Excellent Performer

I have owned a Mewlon 210 for just over one month and have had several opportunities to use it. Overall, I am pleased with the scopes very sharp optical performance, quick cool down relative to SCTs and light weight. Planetary images have been excellent and stars are crisp and pinpoint against a dark background. My only minor complaint is the approx. 30 image shift my OTA exhibits when changing the direction of the focus knob. As far as collimation goes, I have adjusted mine once and it has held collimation well even after being transported. I have the OTA mounted on an EM10 Temma and the combination is solid and fairly lightweight especially for an aperture of 210mm.
