Need some tips on how to increase the nebulosity.
Full spectrum 1100D with ED 80.
Thanks for looking.

Nebulosity? I didn't think there was any around this one?

Nicely framed, but the colour looks a bit pale.

It definitely needs some vibrancy and saturation enhancement, but is otherwise a cracking image.

Despite the name, Kevin is right. There is no nebulosity there.

I third what Kevin and Cam said. Nice job.

Thanks guys,
I had another play with the image, there wasn't too much colouring in the original TIFF stack, so had to bump up the red and green a bit, looks a bit yellowish now.

Did you change a camera or DSS setting Bo? Usually your pics have plenty of colour. This one is almost monochrome.

Nice image Bo, though I prefer the first because it has the jet black background. I don't think much was gained in the second version.
I don't think there is nebulosity here so you could probably try for star colour in you exp plan. It's a nice little group of stars.

I assume that the full spectrum camera will subdue the blue
to some extent.

I remember now that night had a few low hanging wispy clouds and the air was laden with moisture, so much that the moon had a rainbow halo around it! So the colours may well have been suppressed.

Thanks Trevor, yes, I like the darker/bluer image myself also

Not sure Raymo, see my comment above re the air moisture and low clouds. I thought full spectrum mods increase sensitivity in the blue but does become particularly sensitive in the Ha/red part

Full spectrum mods improve sensitivity in the UV part of the spectrum too. Of course for us astronomers the big gain is in H-alpha. UV has a fair bit of extinction from the atmosphere, and the blue filters on your Bayer-mosaicked chip aren't going to let much UV in anyway.
