H 3-75
H 3-75 (also known as Haro 3-75 and PNG 193.6-09.5) is a tiny planetary nebula in the constellation Orion. At 31 arc seconds this is without a doubt the tiniest target I have ever attempted, and a real challenge for 6-inch aperture scopes. This is the first amateur image to reveal the outer halo, which is significantly larger than 31 arc seconds.
The outer halo around this planetary nebula was initially discovered by the Galactic Planetary Nebula Halo Survey (GPNHS) team (a collaboration of some of the world's best astrophotographers led by Sakib Rasool) in January 2019.
Image captured on my dual rig in Spain.
Scopes: APM TMB LZOS 152 Refractors
Cameras: QSI6120wsg8
Mount: 10Micron GM2000 HPS
A total of 37 hours image capture.
