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 , € 4494.98)
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.
