    Default Considering purchasing Skywatcher evostar 80ed



    Hi all I am considering purchasing a Skywatcher evostar 80 ed tube to mount on my Eq5 goto,I was going to get the Skywatcher startravel 102 but was told it might suffer CA distortion.The evostar is 600mm focal length F7.5 and just wanted some advice on the scope,much appreciated.

    A great scope! But if you purchase it the fieldflattener that is built for it is a must in my opinion.
    The difference between those two scope is that the 102 startravel is a achromat and the 80ed is a apochromat. Big difference in the optics.

    I agree with Micke, I own this scope, and it's great for imaging. The dedicated focal reducer is a screw on and squeeze fit (as far as I know) and therefore eliminates elongated stars from tilt and also keeps the camera safe from falling out or rotating.

    Hi thanks for the reply,is the dew shield retractable or is fixed as it does not say on the site I was going order from as I can only contact by email and also is the fieldflattener a must or would I be able to purchase later for the scope.

    The dewshield is not retractable only detachable.
    No the fieldflattener/focalreducer is nothing you have to purchase directly but i think when you start imaging you will want to have one eventually. I think its so with every doublett scope you buy that the stars in the corners and sides will be elongated. Then a flattener is must to correct that.

    Hi ok thanks for the reply,I checked on the site and don't have any in stock at the moment,are these scopes ok for doing deepsky objects as I looked at another site and said it was only good for planets,so I am still unsure as I want to use it with my gpcam290c camera for imaging.

    This scope is really made for deep sky imaging as that im using it for. I never seen anyone used it for planetary imaging but can be wrong.The focal length is to short for it. But lunar or solar it will defenetely work.
    And i suggest you will look into getting an dslr for the scope to go with. Canon or Nikkon is the preferable brands. I think you will find some used very cheap if you look around. Your gcam290 works best for lunar or planetary imaging because it has a very smal sensor on it. And i think it will work as a guiding-cam to.

    Look for a entry-level Canon you can maybe find used for 1000kr or less (100£) Canon 1100D have been very popular before but you can maybe find a 1200D for the same price if you look. Then many of us astrophotographets modify the camera by take away the built in filters so the cam becomes more sensitive in the red wavelenghts.

    HI ok thanks for the reply,I will look into sourcing a camera once I have the scope.
