I am new to astronomy, and recently purchased a Celestron Starsense Explorer LT 114AZ, and just for a start, I used the finderscope to locate exactly a random star, and I looked through the eyepiece and just saw a blurry white image. I was using a 25mm eyepiece lens, and then decided to put on the 2x Barlow lens with the 25mm lens, and nothing changed. Is this normal? What should I do to improve?
Hi, I've got a Skywatcher Heritage 130p reflector, and if i insert anything less than 10mm eyepiece, the image won't get crisp. I guess it's normal, but as I'm very new to astronomy, I'd like to know what the sharpness depends on exactly.
Is that the focal length (how fast the telescope is? ) or the size of the mirror and how much light it gathers? Or both affect it the same way?
Are things the same with refractors in this regard? Thanks.
