Three Emission Nebulae - RCW 59, 75, 104

[Martin Pugh]

Hi folks
I dont think I will pursue any colour for these 3. Typical of these objects, the Ha emission is far more interesting than generating the RGB (Result=red) version.

the exposure times for these are 4, 8 and 11.5 hours respectively.

thanks for looking

Three great monochrome photos Martin.

Amazing detail.

That last image looks like it would be worthwhile getting some colour.

Unusual and unique, not easy to do anymore.

Very nice Martin. Nothing wrong with high quality Ha images. Are you planning to do the whole RCW catalogue?

Cheers

They all look great Martin. What instrument were these taken with?

[prokyon (Werner Probst)]

Wow, stunning results!

Thanks for the comments.
Steve - no, not planning to do the catalogue.

Marc - this is the FSQ106N and STL11K, Astrodon 5nm Ha filter.

cheers

I'm with Greg - love the last one. Not familiar with it at all.
Here's a bit of blurb on RCW 104 for anyone looking for more info:

Agree with Greg, last one of the set looks very interesting and definitely the adding of color would give more power to the FOV.. definitely worth a try
