Popular Post AstronomyUkraine Posted June 1, 2021 Popular Post Share Posted June 1, 2021 18 hours of SHO data on LBN 325 in the constellation of Cygnus. Taken with my ZWO 1600. Gain 139 offset 21. There is little OIII in this target, I collected 4 hours and didn't see much more than the faintest whisper of OIII. The image is a combination of SHO, ForaxX combination then the result was recombined with the SHO in a 50/50 mix. This is the first but won't be the last time I process this data.

Sarum Posted June 2, 2021 Share Posted June 2, 2021 Wonderful detail there Brian, and I particularly like the almost three dimensional effect in the lower right foreground. Roy Quote Link to comment Share on other sites More sharing options...

Roy Thanks Roy. I started this project in April, but the weather gods were against me for most of May. Quote Link to comment Share on other sites More sharing options...

The signal is quite strong in Ha and SII, the OIII is practically non existant. Overall it was quite an easy object to image, but a bit of a pig to process.

julianr Posted June 3, 2021 Share Posted June 3, 2021 Thanks for the details, I have found using a starless image to create the colour image where you can boost the O3 nicely can help. I use pixinsight and can do this whilst still linear using a similar philosphy to JP Metsiviano (apologies if spelt wrongly) Quote Link to comment Share on other sites More sharing options...

I wanted to try something a little different, Cygnus has a lot of little gems hiding away from the usual targets. Quote Link to comment Share on other sites More sharing options...

It was a bit of a struggle with the colours, with OIII providing very little data to the image. Quote Link to comment Share on other sites More sharing options...

The guy who created this method has a Discord contact of ForaxX#0355. This is the dynamic SHO combination he created on the ColdestNights website. https://thecoldestnights.com/2020/06/pixinsight-dynamic-narrowband-combinations-with-pixelmath/ Edited June 13, 2021 by AstronomyUkraine 1 Quote Link to comment Share on other sites More sharing options...
