Elephant’s Trunk Nebula – IC1396
Elephant’s Trunk Nebula
Ran some older data with my newer data off the Hyperstar and Edge HD 8″ and it turned out pretty good. The amount of detail coming in from Hyperstar really helps highlight the nebulas. This also has a mix of good star color from a smaller Meade 70mm refractor, but the nebula was strong in Ha session with Hyperstar.
