Helix Nebula in Ha and [OIII]

by Richard Crisp

Last night I was enjoying some really good seeing and was taking images on two systems at the same time. I may have been so distracted with the back and forth that I may have not taken anything at all that was worthwhile. I am just now beginning to process the data (sunday afternoon).

here is the first data I processed and the last object imaged, The Helix Nebula, NGC7293

It rises late and by the time it did I had finished my data gathering for another project so I took three x 20 minutes in [OIII] followed by the same in Halpha. After the last Halpha shot finished, the sun started to brighten the eastern sky.....

As I processed the data I see that more exposure time would be nice: the data is a bit thin, particularly the [OIII]. But I gave it the best I could with what I had in the can so here it is:
