Finally got down to my rural coastal retirement getaway early April for 2 weeks hoping to get some decent sky time in my NexDome Obs.
Unfortunately the weather was lousy and only managed 2 short clear nights with scattered cloud.
Imaged the Statue of Liberty as it was well placed but only captured a bit of Ha data.
Decided to process what limited Ha data I had as I don’t know whether I can finish the project this year.
Even using a 3nm filter the data was quite noisy due to a Full Moon blasting my Obs and insufficient data to improve SNR.
