What can you see with an 8 inch Dobsonian telescope?
You will be able to see quite a bit! Open clusters and globular clusters will be great, although the fainter globs won’t look like much. Some galaxies won’t be visible due to your moderate light pollution but many will.
Do you need dew shield on Dobsonian?
But again, dew is not the reason to use a “dew shield” with most Dobsonians. It is for ambient light control. We can likely DIY one quite similarly. You just need to find the right material with the proper combination of stiffness and flexibility and then sew on a velcro strip (the sewing is the biggest problem I see).
How big is an 8 Dobsonian?
The Sky-Watcher Classic Dobsonian Telescope 203mm/1200mm (8″) has a “paraboloidal” primary mirror to eliminate spherical aberration and a four-arm, secondary- mirror bracket with fine supports (0.5mm thick), to reduce diffraction spikes and light loss.
Is an 8 inch Dobsonian telescope worth it?
It is bigger and heavier but still manageable in 2 trips. I really like having the extra aperture under dark skies and think it’s worth the extra effort to see more. At home I prefer the 8″ with the lighter weight and quick easy setup.
How far can an 8 inch telescope see?
The most distant galaxies that you will be able to see with an 8″ telescope will be about 50 to 100 million light years away e.g. M109 with apparent magnitude 10.3 at distance 83 ± 24 million light years.
How do you stop the dew on a Dobsonian telescope?
A dew heater is by far the single best method to prevent dew from building on your telescope’s optics. A dew heater works by placing a heated strip around the parameter of your telescope. This ensures that the telescope optics stay above the dew point for the entire duration of your night.
How do I keep my telescope from fogging up?
Central heating radiator foil or an aluminised Mylar space blanket is great for this job. You can also wrap the band of a dew heater around the end of your finder, around the end of your telescope, or around your telescope a short distance back from the objective lens or corrector plate.
Are Dobsonian telescopes portable?
Tiny but mighty, this tabletop Dobsonian telescope features a 4.5″ aperture which provides excellent wide-field views. This ultra-portable system is light and easy to set up.

What is the Hubble telescope doing?
Hubble telescope. n. ( Astronautics ) a telescope launched into orbit around the earth in 1990 to provide information about the universe in the visible, infrared, and ultraviolet ranges.
How are telescopes used in astronomy?
Telescopes are the main tools used by astronomers to explore the Universe. The way they work depends on what an astronomer wants to look for across deep space. For most people a telescope is an optical telescope, which lets an astronomer see objects in space that radiate or reflect visible light.
