Ha tests
How am I supposed to do deep sky with a big bright moon out there? Well I could do Ha I suppose. Just some tests to see what would happen. The Ha filter is a medium bandwidth 30nm, camera was a full spectrum modified Nikon D70s, SW120mm refractor at F4 with Orion 0.8x reducer, HEQ5 Pro unguided with just one 5 minute sub at ISO 400 for each of M16, M17 and M8 / M20. Focus is a bit off.
