I can only imagine what it'd look like in the full HST SHO palette!

Thanks very much H. I will persevere with colour, but am not very skilled in that area.

Do we know how drizzle is different than dither?

Thanks very much John - that is a very generous comment.

I guess the difference between this and the big boys on the hilltops is that they can routinely get a good set of hi res data in a single night. It took me a couple of months of scratching around to find and use the rare periods of fairly good seeing - being close to the sea has advantages, but good seeing is not one of them - it was still fun though.

As I understand it, dither is required to move the stars around in the subs. Drizzle upsamples and fills in missing data using offset real data from the dithered images, rather than interpolation. In that way it recovers some of the information that was scrambled by undersampling in the original images. Should work really well with your system - might be an alternative to the smaller pixels that you mentioned in another thread. Maybe worth a read http://www.adass.org/adass/proceedings/adass99/O6-02/

Soooo, that from a simple fast Newt and little starlightxpress huh? ....well, must get me one of those

The seeing, careful sub selection, and drizzle aside, t'is quite amazing sir

Mike

Thanks Mike. Yeah, these little cams are pretty cool eh - go well with a fast Newtonian. Actually it was good fun seeing how far the system could be pushed - there is some very capable software out there now.

That definitely deserves one of these ...

You're certainly throwing down the gauntlet to the rest of us would-be imagers aren't you! Now let's see the colour!!

Wow, thanks very much Marcus - very generous of you. All right, I will keep trying with colour, but I have a lot of trouble with it.

There is hope for all of us who have Newts. instead of RCOS systems.

cheers

Hi Allan. Thanks for the comments. I would still accept an RCOS if anyone wants to get rid of one

Thanks again Marc.

Wow!!

Very clever data capture and selection plus inspired use of processing tools, for a simply fantastic result

I for one, will be going back to the drawing board.. I think you set a new standard here Ray. Well done

Very generous of you Peter - thank you. super-resolution might be very useful technique for your RH - you could maybe try for a 64mp image at 0.8arcsec for example...

Hi Dave. yep, StarTools is a must have in my books. I concentrated solely on the nebula and left the stars to look after themselves - StarTools cleaned up the mess that resulted very effectively - possibly too well .
