Description

NGC7822 is part of the question mark nebula. Last year I shot the whole nebula through Tak-85edx. The core is still very appealing with young star in make. So this one target the core entirely. Comparing to last couple of faint objects I shot, this is very bright. It is very enjoyable to collect strong signal.
