more data for the Gemini (Halifax)

I wanted more data on the planetary Gemini Nebula aka NGC 2371. Sent BGO off. First imaged 27 Apr '16.

Gemini planetary nebula in oxygen

Ionized oxygen only, 60 seconds subexposures, 10 stacked shots. Bright!

Gemini planetary nebula in hydrogen

Hydrogen alpha only, 60 seconds subexposures, 10 stacked shots. Dim!

For all: FITS Liberator, Paint.NET. North is up; east is left.
