A compact and lightweight scope for guiding: QHYCCD's miniGuideScope
A lot of people who undertake astrophotography, whether they are beginners or seasoned amateurs, opt for high quality small aperture, short-medium focal length telescopes such as BAADER APO 95/580 CaF2 Travel Companion (#2300095, € 3850,-) or the 8" Celestron Rowe-Ackermann Schmidt Astrograph. These telescopes will give a relatively wide field of view allowing images to be taken of spectacular large celestial objects such as the North American Nebula, Andromeda galaxy, Orion nebula, Pleiades open star cluster and many many more. Guiding is essential for taking long exposure images of such celestial objects. Long gone are the days when your guidescope was a telescope that would be similar in focal length as your imaging scope and you would guide by looking at a star through a high power cross-hair eyepiece making rapid adjustments manually! Nowadays with high resolution, sensitive image sensors and advanced software imaging algorithms that allow sub pixel star centroiding, smaller aperture shorter focal length telescopes can be used for guiding. If you want a lightweight and compact guidescope to complement your imaging setup QHYCCD's miniGuideScope (mGS) could be just for you. The mGS is available as OTA only and also as OTA with mounting bracket. The telescope: size and...

Celestron CGX mount in combination with StarAid Revolution as guiding cam
The CGX: A Versatile Mount For Everyone! Recently I was able to work with the Celestron CGX, the Baader Apo 95/560 Travel Companion, the Nikon D810A and the StarAid Revolution as guiding system for the first time. Once again the results proved how much you can get out of a good system if you take some time to tweak the settings a little bit instead of simply working with the factory settings of the software without taking a closer look at them. To get straight to the point: I'm really excited about what the CGX delivered last night! For polar alignment, I used the star Regulus and the integrated AllStar Polar Alignment (ASPA) system of the CGX. My alignment routine only consisted of a 2-star alignment, with Regulus added as another calibration star. Then I let the mount slew across 2/3 of the sky to the star Vega. The CGX placed Vega in the middle of the field of view of the APO 95 and the Z6, with less than 5% deviation! That's AMAZING, because it means that I don't need an additional high-precision goto, even with small sensors! In any case, high-precision goto is only intended for those times when the...
