Basis for serious entry into a hobby

The Skywatcher Evostar 90/900 (actually 910) is certainly a good refractor telescope for the serious introduction to the hobby astronomy and at a good price. Below I would like to describe my experience with this telescope and supplied to mount (EQ-2). Perhaps this description helps.

Positive is the first place, the low weight of the tube. And with a focal length of 910mm the telescope is hence very quickly supported by the length of her time in the garden or loaded into the car and then rebuilt and ready for viewing. On the Moon and planets, it makes itself very well. However, one should not expect a "Hubble images". In particular lunar observation is with this refractor for me a pleasure (for I had me worried). The Maria are very nice to see and be finely displayed, as well as the mountains and craters. It remains the "chromatic aberration" in my view very within narrow limits (Fraunhofer telescopes show at high magnification and extremely bright objects due to design an Blausaum). What in this refractor sure predominantly located at focal ratio (here f = 10.11) and the built-in lenses. I guess I was lucky, because in telescopes in this price range, the final quality control is probably rather thin, so good grottige and telescopes are to be found in one batch. This refractor are useful to about 180-fold magnification.

The supplied eyepieces (25mm and 10mm Plossl) are useful and only rich even try. Since the eyepiece is sized at 1.25 ", more common eyepieces to be used without any problems.
Also the 90 ° diagonal mirror is useful and brings quite good performance. Like the Barlow lens (1.8x). Very positive I find the 6x30 finder. That is in my opinion really good (and important!). Because it is mounted with a standard foot, may also without major problems such as instead a red dot finder attached (if you like). The focuser has some play, but running quite smoothly.

The mount is very light and easy to assemble. But you should be clear about the pros and cons of equatorial mount and the fact that there are dealing with an EQ-2, ie the dovetail is not (!) Easy to change so as for larger (and more expensive mounts) is common and it is a light mount.
The tracking over the waves, I found some little hakelig and the ringing is sometimes a Frustration.Mit some "modifications" can minimize the but. And with quiet (very quiet) hand often goes that way.

Conclusion: A fine optics with practical accessories, which is suited for a serious introduction to astronomy. The mount but is undersized and requires a lot of sensitivity, patience, frustration tolerance and a few modifications (in conjunction with this refractor). However, against the background of the price of this set, I can say that I am satisfied with the purchase. The EQ-2 I quite quickly replaced with a much better mount and this is now really a treat!
