The importance of getting a good focuser for your telescope
No matter how much money you invest in a telescope, it will only be as good as your focuser. Even the most expensive mirrors and the widest apertures won’t help you much if you can’t get proper focus. High resolution doesn’t mean much when the object you’re viewing is out-of-focus, with fuzzy edges and blurry details.
This is why it is important to find a good quality focuser for sale, so that you get to benefit from a fast and smooth focusing ability and spend more time admiring or studying celestial objects rather than struggling to acquire decent focus.
Many models on the market come with high-grade bearings, precise focusing knobs and some even have electronic modules such as Orion’s Autostar, which help immensely in getting the celestial object you want in focus without wasting half an hour to get it.
Make sure you get the right type
While this might seem obvious, you want to make sure that you get the right type of focuser. Some are compatible with reflector-type telescopes, others with Dobsonian focusers. Many adapters are designed for a specific diameter mount, such as a 2” or 1.25”. You also want to check which eyepieces it can fit, so that you don’t hamper your magnifying ability by getting the wrong adapter.
You might also want to check electronic focusers. These can command a higher price, but they can come in quite handy, since you’ll be spending a lot more time admiring sharp and highly-detailed views of planets, stars and galaxies instead of fumbling with the focusing knob for minutes at a time.
Improve your astrophotography with the best adapters
If you’re a passionate photographer, it’s not a bad idea to try to get the best telescope adapter that’s specialized for cameras. These can allow you to obtain great results and capture distant planets and colorful nebulae in amazingly high detail, and all that with a minimum investment.
Don’t forget to check the type of adapter and to make sure that it fits your camera model. For example, for a Nikon D3 you could use a Solomark 42mm adapter, while a new Canon model could require a totally different gadget with a smaller/larger diameter.
