My effort from Derry last night - once I remembered to remove the cover from the field flattener. Doh.

I know the North America Nebula is done to death, but this is my first time imaging it, and also my first time trying the Triad filter with my Nikon. I'm in the middle of the city but I was able to take 5 min subs! I processed in PixInsight, but didn't even have to do background extraction. I used photometric colour calibration to restore natural colour and then just did a bit of mild tinkering. I'm impressed by the Triad filter on my first try.

Comments welcome - maybe I should try a star mask and try to bring out star colours?

That's nice. Can't give any advice about the processing as i use PS mainly but i suppose more data may help with the star colour. Looks really clean for just under two hours. 

Maybe getting some short rgb subs for the stars would be the way to go.

It's an interesting filter, i have one of those duo narrowband filters on the way to me. Should you be processing the channels individually then combining them again like a typical SHO image?

Lovely image and impressive results from the Triad filter. Did you get direct from OPT?

Thanks Dave, yeah, I got it direct from OPT. I don’t think there’s any other option at the moment.

That’s a good idea about the star colours - but it would mean significantly upping my game in PixInsight! I was so pleased with the Triad filter from a red zone, and similarly impressed with PI’s photometric colour calibration for restoring normal colour balance.

      Hi all
      I'm still transitioning from an unmodified Canon 200D to an Altair Astro 183C pro. I think this might be my best image yet, and the first time I have tried a mosaic.
       
      Its made of two panels, each panel has 20x120s + 30x60s. Stacked and stitched in Astro Pixel Processor and edited in PS CC 2018. I'm pretty pleased!
       
      Scope is a SW ED80 DS pro (reduced to 480mm, f/6) on a HEQ5 pro. Guided with a QHY5L-II in my finderscope.

      Messy I know, but with what I have to work with atm, I'm really happy so far. Hoping to add more data

      Two clear nights running to try out my new Samyang 135mm with the 428ex.
      This is 24x300s processed in PI: DBEx2, MaskedStretch, HDRM + LHE.

      I know this combination produces significant undersampling but that aside I am very pleased with the widefield capability now available with the 428ex.
      Thank you for looking.

      Not much to look at compared to the amazing shots people are taking, but with reasonable seeing and an atmospheric refraction corrector I managed to get a little detail from 55 degrees North. Beginning to get the hang of the data acquisition bit - sort of.
