    Default Skywatcher Evostar-90 EQ3-2



    I recently bought this scope with additional Dec and RA motors and have so far been able to watch the Moon, Saturn and some stars. Does anyone here have any experience of this model and of its eye pieces and other original accessories? I am still a happy beginner with the scope and am really looking forward to exploring the sky with it.

    I'm guessing it came with a skywatcher 25mm and 10mm eyepieces? With the 900mm focal length that translates to 36x and 90x magnification. You could try experimenting with 2x, 2.5x and 3x barlows, which should give you larger images of the planets themselves. A 2x barlow will increase your magnification by a factor of 2, for example. Depending on how bright some objects are you may want to invest in some filters; but it's best you determine this for yourself. Watch the moon; is it too bright? If it is, you may want to invest into a neutral moon filter. I'm a beginner at this myself so you might want someone else's advice on equipment for it though. From what I can tell, that should be a very nice scope.

    Hello newman and thanks for your comments. It came with those eyepieces and a 2x Barlow and I have been quite happy with them so far. The bright Swedish nights make the summer a bit off season for astronomy but I have been able to watch some double stars and film the moon and Saturn. Next thing will be Jupiter. I have a moon filter and have also borrowed some filters intended for a camera just to evaluate if colour filters are any good for me. I think it feels like a good scope but my experience is very limited so far. I am thinking of maybe getting an eyepiece giving me a magnification of approximately 120-140x since I think it a bit big jump from 90x to 180x.

    Sounds like a plan, let me know how those color filters work out for you. I bought my first scope 3 days ago and hope to be able to try it out either tonight or tomorrow night. Got a 2.5x apochromatic barlow with it, curious about it's performance. Reviews suggest it's a good piece of kit, in theory I can get 250x magnification if used with the 10mm eyepiece but in practice, I'm not entirely sure that magnification will be practical/usable.
    At any good luck and clear skies!

    I have only tried the filters on Saturn once and maybe (just maybe) I saw a little more contrast on the belts with a light blue filter. I just want to try things out a bit before spending a fortune on filters. You can probably sometimes use 250x magnification on for example planets. I have experimented with putting the 2x Barlow before the diagonal instead of after it, this gives me 3x instead of 2x. The result was probably 270x magnification (more than 180x which is "maximum" for my scope) which made Saturn bigger but darker. Focusing was difficult.
