Heart nebula in H(HO)O and HOO

[geeklee]

Hi everyone - In a very surprising set of clear skies this image was taken over four nights in November - two long and two shorter - between 3rd and 21st.

This is using a RedCat 51, Atik 460EX, filter drawer and standard Baader Ha and OII filters.  Image scale is ~3.8"PP.  A good fit on the smaller chip in one frame, but some detail is sacrificed at 250/51.

Captured with Voyager, calibrated and stacked in APP then processed in PixInsight.

Ha - 48 x 900s (12hr)
OIII - 52 x 900s (13hr)

The Ha data was amazing and the first time I've ran an autostretch in PI and seen negligible noise in any area of the image.  A large part of processing time was spent trying to reduce halos in the OIII stack before combining (there were 8-10 that would have created big blue circles if left alone) and balancing the background (which may or may not be a success).  

There's a couple of palettes here - one H(HO)O and one HOO.  The first being 50% Ha and 50% OII into green and the second perhaps needing some anti-saturation sunglasses 😁

As always, thanks for looking and any feedback for improvement is always welcome.

Love that, I must seriously resist the temptation to buy a mono camera!
