Backyard Astronomy And Other

I have been using the new Antlia light pollution filter: This blocks the part of the blue that LEDs produce. All other LP filters work on mercury vapor lights, but virtually useless with LED’s.

The following image of M33 was made last week using a 6-inch refractor and one shot color camera ASI 071, using an Antlia RGB ultra II filter.

I wanted to add what can be seen “visually” from a ~6.5 suburban sky using a 10-inch f/4.5 Newtonian. Roger
