PIER-14 Images

First process of Job 1239 - IC2177 the Seagull Nebula.



We lost a lot of subs to poor sky conditions so in the end this was only made from 16xHa, 17xO3 and 20xS2 - all at 240s exposure. 

Processed in Pixinsight with Ha as a pseudo-luminance.

O3 and S2 were pretty noisy and I may resubmit those two filters for additional data.

That is most welcome to see Richard and I'm liking what you have already achieved from the data since I'm aware of how much recent imaging has been affected by the weather. You have managed to frame it very nicely, a lot in there to see. I can't recall when you originally suggested this target, but I know it was some time ago. Certainly it has been worth the wait.  

I have been running 'blink' on the data we have received these past couple of weeks, and finding a lot of the data affected by the sky conditions, something which frequently happens this time of the year. The question therefore is what do I have a go at next bearing in mind how much time it can take to get to the end of a first process on pier 14. So you have greatly helped out with this decision. 

Please submit a job to replace the unusable data since it will not be possible to frame this target without a mosaic once the scope is altered.

Hope all is well, 

Cheers,

PS 
Perhaps you'd consider reposting your image on the new topic I've just created for images processed in 2022. 

This is an attempt with the recently completed vdB-152 data in LRGB. [attachment]vdB-152.jpg[/attachment] I found it quite tricky to pull the nebula out of the murk, and ended up with some visible artefacts on the brighter stars that need individually treating. But this is probably the weakest object I have yet managed to generate a usable image from.

Indeed, a tough one. I have also made an attempt. I included the Ha data as well. As I am new to multi-channel image processing (I only own an OSC), maybe you have some tricks to improve on this.

Manuel,

That is very nice. I did mine before the Ha was available, so it is probably time to have another go.
