Sh2-119

Last astrophotography done mid-July on 5 straight nights.This is Sh2- 119 show nebula from the Sharpless catalog, located in the Swan constellation.Little photographed object, dark and H-Alpha gas areas and especially Oiii can be captured with long poses.Especially since the moon was well present, so I used my L-Extrem filter to capture the signal from these two gases.I used a PixInsight script from Zloch Team Astro (again thanks for all you tutorials if by chance you see this message..) to create a layer of Sulfure gas and mix all three layers into SHO - which results Interesting.The 10 min posing times will have allowed me to be even more picky on my stationing and self-guiding. At this time we don't really have the right to ' about ' anymore.A huge thank you to Yann Sty for all his tips: settings + treatment.Matos+exives:- EQM35 Pro mount driven via EQMOD- bezel TS 71 SDQ f / 6.3- ZWO ASI 2600 MC camera / gain 100 offset 50 / cooled to-10°C- 90 x 600 s or 15 h with the L-extrem- 20 x 120 sec in RGB with IDAS LPS P3 filter for stars- 50 DOF- pre-treatment + extraction of Ha and Oiii layers with SIRIL- treatment with PixInsight and Photoshop.

Last astrophotography done mid-July on 5 straight nights.

This is Sh2- 119 show nebula from the Sharpless catalog, located in the Swan constellation.

Little photographed object, dark and H-Alpha gas areas and especially Oiii can be captured with long poses.

Especially since the moon was well present, so I used my L-Extrem filter to capture the signal from these two gases.

I used a PixInsight script from Zloch Team Astro (again thanks for all you tutorials if by chance you see this message..) to create a layer of Sulfure gas and mix all three layers into SHO - which results Interesting.

The 10 min posing times will have allowed me to be even more picky on my stationing and self-guiding. At this time we don't really have the right to ' about ' anymore.

A huge thank you to Yann Sty for all his tips: settings + treatment.

Matos+exives:

- EQM35 Pro mount driven via EQMOD

- bezel TS 71 SDQ f / 6.3

- ZWO ASI 2600 MC camera / gain 100 offset 50 / cooled to-10°C

- 90 x 600 s or 15 h with the L-extrem

- 20 x 120 sec in RGB with IDAS LPS P3 filter for stars

- 50 DOF

- pre-treatment + extraction of Ha and Oiii layers with SIRIL

- treatment with PixInsight and Photoshop.
