Celestron is not only changing the way we experience astronomy, but we’re also changing the way you interact with the night sky. The Astro Fi is a fully featured telescope that can be controlled with your smart phone or tablet using the free Celestron SkyPortal app. Celestron’s SkyPortal app replaces the traditional telescope hand control […]

Galileo 1100x135mm (5″) DB-135 Reflector Telescope I purchased this scope last week and in general it’s not bad, a nice alternative to my refractor. Some nice views of Jupiter with 25mm but no final verdict until I have collimated this. The Dobsonian base is a little annoying as it moves really smooth until you get […]

The main advantage of an 8 inch telescope over a 5 inch one is when you take long exposure photographs. The NexStar mount isn’t good enough for exposures longer than around 30 seconds. The planets and the Moon will look the same in both telescopes unless you live in the desert away from city lights. […]

This is my 4th video in my series about Dobsonian Mount telescopes. It is all about understanding eyepieces and their relation to the telescope. Learn how to determine the magnification of an eyepiece with your telescope and how to choose new eyepieces.
