After looking at the reviews for all the reflectors in the £100 to £200 range, and looking at reviews and info on other websites I decided to go for the Skywatcher Explorer 130m. I went for the motor drive just in case I needed it as some reviewers said I would. I also bought a moon filter which is a must.
I found the scope ok to assemble. You just need to get your head around what everything does by reading all the instructions carefully. I found aligning the red dot with the scope quite easy - in the day I focussed the scope on a double chimney a quarter on a mile away and then set the red dot. I was amazed at how well the scope works in the day even with the 25mm lense. I couldn't wait for a clear night. Unfortunately due to torrential rain and wind I had to wait a while.
Tonight it was very cold, very windy but a clear sky. The scope was excellent. I saw Jupiter and two of its moons with the 10mm lense! I also viewed the craters on the moon which were amazing. The only problem I had was the judder from the wind, however as I said this week is very windy with gale force winds forecast all week (13/12/11). The lenses seem fine to me. The barlow is excellent and gave particularly good detail of the moon - too windy to use on Jupiter because of judder. Excellent piece of kit for the price, very well built.
One other thing - I have an app on my iphone which finds stars etc and has red night mode, the app is called 'star chart' - this is excellent as it finds constellations, planets, stars or messiers so you know what you are looking at and where to point the red dot finder, and it doesn't blind you in the dark. I also have a planisphere which is useful for the price you pay.
Not used the moter yet to track but it is offputting when Jupiter, or the moon for that matter, constantly move off out of view, so you have to keep tracking manually. Hope this info from a very happy beginner is useful.
