Basic tutorials are free and can be watched on youtube. My advanced tutorials are for astrobiscuit patrons. You can become a patron for £3 a month. You can leave after one month after watching the videos if you like! Patrons also get access to hidden channels on the astrobiscuit discord server (where the astrophotography experts hang out), sneak peeks at my upcoming videos, higher level patrons get other benefits including having their names appear on the videos and one on ones which might be useful if you want to check that you’re buying the right stuff before you buy it.
