Strategy for file size with drizzling

[jerryyyyy]

My nebula season is over and have been turning to more conventional targets with my 500mm Tak 180ED.  I have come to the cosmic realization that this scope is under-sampled and that it is ideal for drizzling.  But the files are large and I normally do not collect anywhere near as many RGBs and Ls.  So really it is the Ls that get drizzled. 

So in coloring the L, should I also double the size of the RGB by upsizing using the resample proc? 

Is this Standard Operating procedures, or is there some clear trick or gotcha I am missing.

Bumping myself here.  I just decided everything is 2X.

If anyone has any more insights on drizzling am all ears as i have read all the other posts.

Hi Jerry,

I have always applied the same Drizzle to all the filters.  I guess there's no rule that says you can't just upsample the colour to match a drizzled luminance but I find it neater to process them all the same.

Cheers,
Rick.

Sez in the hand dandy instructions results are best for drizzling with large numbers of subs... and I generally have fewer RGBs than Ls.... Also use a blurred RGB image and get detail from L so not much point trying to get a very precise RGB image...
