QHY Mini Guide Scope is a 30mm f/4.3 (130mm FL) telescope. When the pixels of a guide cam becomes small and QE become high, you may not need a big one. Read More » QHYOAG QHYOAG off-axis guider includes a precision 1.25-inch helical focuser that accepts our QHY5II and QHY5...
摘要:A telescope mirror is exposed to the elements almost every night, year round. The winds on the summit of Maunakea blow small pieces of dust and debris into the dome. And, while the mirror is covered during daytime hours, it is impossible to protect the mirror at nig...

Hard X-rayscanning observationFormation flightSuper mirrorSDCCDA formation flight astronomical survey telescope (FFAST) is a new project in hard X-ray covering a large sky area. In particular, it will focus on the energy range up to 80 keV. It consists of two small satellites that will go ...
Since we can use a small-size detector such as the X-ray CCD at the defocused position, the telescope system gives an opportunity to make a high-resolution spectroscopy with a high-angularresolution and with a large effective area.Yoshitomo Maeda...

Two instruments adopting this optical design were actually built: AquEye (the Asiago Quantum Eye) for the Copernicus telescope, later upgraded to AquEye+, and IquEye (the Italian Quantum Eye), to be mounted on 4 m class telescopes such as the ESO NTT in La Silla (Chile) (Figure 1 shows...
