Telescope:
1. A catadioptric telescope equiped with altazimuth mount such as Meade ETX (Maksutov Cassegrain) are very portable. It's capable for viewing planet and bright DSO ( Deep Sky Objects ). It's suitable for planet photography but not deep sky imaging due to its slow F/ ratio ( long focal length ). Another case if you use focal reducer.
Other than Mak, there is Schmidt Cassegrain (SCT) which I am using now. Its focal ratio is always around f/10. With a f/3.3 focal reducer, your field of view is greatly increased.
2. A reflector equiped with equatorial mount such as Celestron C6-NGT are very fast ( low focal ratio ), especially Schmidt Newtonian. It's good for deep sky observing and photography. A equatorial mount with counter weight is heavier than the telescope itself. It's around 1x KG ( C6-NGT ). By the way, its aperture are much higher than the same class of catadioptric telescope. For instance, Meade ETX-105AT(4.13") costs RM4900 while Celestron C6-NGT(6") costs RM5200.
3. Refractor is the royal family of telescopes. The refractor has the highest contrast on planetary object and deep sky objects. You can get an 8" SCT (200mm) at the price of a 90mm triplet apo.
I have 2 dealers to recommend to you. They are K.K. Looi at Infinity Infocus and Jason Tan at Trifid-Optics.
