Foundational guides on choosing and using a telescope.https://gototelescope.com/en-UShttps://gototelescope.com/guides/choosing-a-telescope-for-planetary-imaging/https://gototelescope.com/guides/choosing-a-telescope-for-planetary-imaging/The one branch of astrophotography that works from a city balcony on a modest mount. Everything depends on aperture, optics and the atmosphere instead.Sat, 02 May 2026 00:00:00 GMThttps://gototelescope.com/guides/choosing-a-telescope-for-galaxy-astrophotography/https://gototelescope.com/guides/choosing-a-telescope-for-galaxy-astrophotography/Galaxies are small. Image scale decides whether you record structure, and your mount and your atmosphere decide how much scale you can actually use.Sat, 25 Apr 2026 00:00:00 GMThttps://gototelescope.com/guides/choosing-a-telescope-for-nebula-astrophotography/https://gototelescope.com/guides/choosing-a-telescope-for-nebula-astrophotography/Nebula imaging is where a small cheap telescope genuinely competes with an expensive one. Work through framing, focal ratio and total system cost in that order.Sat, 18 Apr 2026 00:00:00 GMThttps://gototelescope.com/guides/image-circle-and-sensor-compatibility/https://gototelescope.com/guides/image-circle-and-sensor-compatibility/Two numbers decide whether your corners are clean: the telescope's corrected image circle against your sensor diagonal, and whether your adapter stack hits the specified backfocus.Fri, 10 Apr 2026 00:00:00 GMThttps://gototelescope.com/guides/why-the-mount-matters-more-than-beginners-expect/https://gototelescope.com/guides/why-the-mount-matters-more-than-beginners-expect/A modest telescope on a good mount beats an excellent telescope on a marginal one, every time. Here is why, and what to look for.Wed, 01 Apr 2026 00:00:00 GMThttps://gototelescope.com/guides/refractor-vs-reflector-vs-compound/https://gototelescope.com/guides/refractor-vs-reflector-vs-compound/Lenses, mirrors, or both. The choice sets your cost per millimetre of aperture, your maintenance routine and your field of view — and it is far less about image quality than the arguments suggest.Sun, 15 Mar 2026 00:00:00 GMThttps://gototelescope.com/guides/focal-length-and-focal-ratio-explained/https://gototelescope.com/guides/focal-length-and-focal-ratio-explained/Two numbers that get confused constantly. One decides framing and magnification; the other decides how quickly a camera records extended objects — and neither makes a visual image brighter.Sun, 08 Mar 2026 00:00:00 GMThttps://gototelescope.com/guides/how-to-choose-a-telescope-for-visual-observing/https://gototelescope.com/guides/how-to-choose-a-telescope-for-visual-observing/Most first-telescope regret comes from answering the optics question before the logistics question. Here is the order that actually works.Sun, 01 Mar 2026 00:00:00 GMT
