NGC3628 LP filterd luminance*Extra data added

[MikeD]

First time using a CLS filter in years for me.

It allowed me to shoot 10 minute subs which made for a clean background with a relatively short data set.

17 @ 600 seconds with the 10" newt and HX916.

needs more time to bring up the galaxy but I am pleased with it so far.

The colour data will be the real test as the main reason for not using this filter is the fact that it kills the red channel dead.

see this thread for more details.

Lovely image Mike. Love the dust lanes.

[symesie04]

Very impressive. Look forward to seeing the completed article.

[MikeD]

Thanks guys.

Could you shoot L with the CLS and RGB without, or does it not work that way?

[MikeD]

I could but that would mean breaking down the imaging train to remove the CLS filter which would mean fresh flats after each change and I would like to get some LP reduction in the red channel as well.

Binning the red data x 2 and shooting the same length subs as the green might be an option but I will try the R,G,B+ CLS as my G2V calibration suggests (R = 3.9, G = 1, B =1.2) first if that works I will just go with that.

Another super hi res shots mike....nice job

[Beyond_Vision]

Really nice to see this up close a cracking start Mike. I know what you mean about the CLS filter I hate the cast my clip filter has on my DSLR widefield images. I may invest in a Hutech IDAS version as this has less of a cast.

Hi Mike,

Thats looking fairly impresive ...even at this stage. Can't wait to see how this project evolves...

Well I got the extra luminance data to allow me to bring the galaxy up, I managed to bring up a few dozen background galaxies too.

The image is now

39 @ 600 seconds.

Beautiful detail.

A little 2 o'clock drift on the stars but that's really nicely detailed!

[morimarty]

Phenomenal detail in the dust lanes mike, interesting about the cls killing the red channel.

Yes I see a slight drift but I think you will find it is at 8 O'clock.
