Can you make Blue from just the Red and Green

Not sure which topic this belongs in so this will do...

Tonight, like a lot of nights , I have been niggled by
cloud, tracking problems, you name it, it has been thrown at me
tonight!

I was ready to take the last set, the Blue set of my RGB set
and I've been shut down by the homemade worm gear failing!!
I'm too heartbroken to go into what's failed, when I've cooled down
in a day or so I'll write up the damage in the ATM thread....but for now,
is it possible to synthesize the blue from the Red and Green already
captured?

Steve

Steve,

Sorry to hear about the worm failure. I know you can synthesize the green from red and blue (there's a carboni action that does this) however I'm not sure about blue from red and green. I always start with red and do blue second for this reason.

Dang, thanks Peter.

Edit: actually it's not as bad as I thought. I ripped the gear apart in the dome
5 mins ago and give it a quick clean with petrol and a toothbrush.
Knowing my luck I will probably blow up from the highly explosive
air I'm sitting in as I type. Gear face looks much better with the grease and
aluminium shavings cleaned away so I can see the damage.
The scope went into a nosedive as the worm drove itself completely
out of mesh. I caught it as it had gone about 15-30 degrees of
scraping worm across 'mountaintops' of the wormgear!
When I saw that happening naturally I was gutted, kinda like the
feeling of dread I feel when the mother-in law is coming over...

Looks pretty good, no obvious scrape marks, but I'm at a loss to
why it was able to drive itself out of mesh?. It's all locked and bolted
solidly in mesh. I think possibly the worm cradle thrust bearing has slipped
out of centre somehow....

Steve, have you only got G and B? If you have L you could try subtracting G and B from that.

Andrew,

I have Lum from a few days ago, different seeing, smaller stars.
I have Red and Green from last night, Blue missing......

Can I work something from that?

LRGB<--- newbie

Have a look at this method:

I used it to generate the image in this thread:

Of course being narrowband my colours are synthetic but I cannot see why you could not apply a similar approach to LRGB.
