You should probably increase the count by a couple of magnitudes ;)

Only problem is 50000 is the limit Moray has for photon count

Really? That sounds strange, having tens of millions of photons in a scene 
is not at all unusual. Perhaps someone should notify the author. If Moray 
supports it, you could use spacing instead. Just remember that halving the 
spacing value increases the surface photon count four-fold, and media 
photon count eight-fold.

Moray does support spacing, but it has both photon count AND photon
spacing, not either/or, and once you set photon count youc can't set
it back to 0.

and what is the problem to hand-edit .pov code ?

I hand-edit .pov code and later change something with Moray,
I have to re-hand-edit the code again.  My scene is not yet
finished, I consider lighting a finishing touch kinda thing.

Hello,
I'm used to compose my scenes in Moray and hand edit code a lot as well.
I usually save the parts I edited -and want to keep so that- in separate
files.
