Title: M27 O3, Ha & 80a draft image
Post by: Rocket Pooch on Jun 08, 2005, 06:38:00
This has potencial :smile:

40 frames 80a x 2sec, O3 x 16sec & Ha x 17sec.  LX90 F3.3 SAC8

I've done a 5 min process, will do a better one for the Gallery, this one is a little Green, to much O3, wonder what it will look like if I swap the O3 & Ha?

definitely a bit too green, especially some of the stars. Looks like the raw frames have a goodly amount of detail tho'. Look forward to seeing v1.1

Yep I think I need to adjust the histogram on the B & R channels to compensate for the G.

you done anything recently :smile:

Hi Ian,

I adjusted the Ha and tones down the 80a, I think your right it looks a bit better now.

Bye

I guess it depends what you're trying to bring out in the way of detail.  I think the first shows more detail than the second, but that maybe something between the two would show more.

I think the blue stars are funny, I probably need to reduce the luminence of these to balance them correctly.  This colour stuff is odd.

Yeah, you're right, they are a bit. Greg has some trick he uses to take stars out while he adjusts things that bring out nebulosity. Maybe, along with the Ha and OIII, you could use an unfiltered image?

Hi Chris,

The red image looks brilliant to me - if only I can do that with me LXD75 i'd be well happy.... I might give it a try with the Toucam soon
