 {{ :dewshield.jpg?nolink&100|}}A lens hood/dew shield has been demonstrated to improve the contrast in images. Some have a base with prongs that lets light in if you aren’t careful, so look for one with a solid bayonet-type base. A lens hood is easy to 3D-print, but if you buy one you’ll find them from $15 to $40.
-{{ :screenshot_2024-06-18_at_9.42.49 am.png?nolink&50|}}Some people find a Bahtinov Mask handy to check the focus. When it’s in front of the lens you’ll see a tiny X over a bright star, you adjust focus until a vertical line equally splits the X. Every time I use mine the auto focus is spot on, so YMMV (Your Mileage May Vary). $12 -$20
