Stars have beautiful colours.

Unfortunately being point like sources, when imaged they often saturate to white.

I am led to believe one of the techniques Akira Fuji used to enhance star colours in his beautiful wide field vistas was to place a soft focus lens over the objective for the last minute or so of the exposure.

With some trial and error I finally developed a photoshop technique that does the same, and applied it to some old data (what else can you do with this weather! :rain: )

The result of my "digital Fuji" processing can be found here...

Hi Peter,

The only problem is that it seems to have induced diffraction spikes as well...

You could take the cross hairs off the AP155 during this weather.

:lol: Ah...that would be due my going through a diffraction phase at the time...or was it fazed diffraction.... :)

looks nice... diffraction spikes are pretty, dont let anyone tell you differently. :)

Do you feel like explaining the process used to do this? or is it a Peter Ward Trade Marked idea? :)

Interesting image Peter, I'm not a spike person myself, although I have tried it with varied results, yours looks great though.

I like the spectral type diffraction spikes, always makes the 70-80's Dr Who theme start playing in my head...which degenerates into a verse of "Doctorin' the TARDIS" by the Timelords. :rolleyes::screwy:

Last couple of images have been stunners Peter, always look forward to them.

I like the result diffusers give, in fact I used my one (Cokin diffuser filter) on my friend's camera last night. It's nice to retain that star colour.

I've found the photoshop way of doing it is somewhat effective, depends on the image :)

Your shot looks OK although I think it's perhaps overdone a bit though, but that comes down to personal taste :)

Lovely colours and sharp stars.

I like the spikes and blue halos, atristic, different.

Fred, you'll find the brown paper bag at the usual spot :)
