ZWO EFW Update

September 4, 2021 - Reading time: ~1 minute

Added the Antlia 3nm Hydrogen-alpha filter in the ZWO filter wheel, and took a pic, added labels to make sure I remember where the filters are. Before this switch-up I had two near-infrared filters (a 680nm and 850nm) in slots 4 and 5, with my Astronomik 6 nanometer Ha filter in the first position. And just to make things as uncomplicated as possible I have the OIII (Oxygen 3) filter in position 2, and SII (Sulfur 2) in 3.
