Questions & Answers

  • what dew heater do you recommend for this scope? Preferably one that will work with a USB batter pack as I don't want to purchase a controller (I am a begginer astrophotographer).

    This dew heater would work for it, it's 16.9" in length and USB powered

  • Is this good for taking pictures of the moon?

    The RedCat is a short focal length scope (250mm F/4.9) which gives it a pretty wide view of the sky.  The moon would fill about 40 to 50% of the view if taken with an ASI224MC camera.  
    Please see the attached image for a simulation of what the moon would look like.
    To have more magnification, a scope with a longer focal length would be used.
