SGL7 M101 WIP 2 now with Ha - The End ?

[Spikey]

I'm really pleased with this only being my second proper RGB image.

Probably my best image to date and my longest data collection period on any image.

I've spent the morning playing with this on the netbook as I haven't got anything better to do. Still not taken any FLATS but judging by how the image looks now I'm not going to bother.

I dumped nearly 2 hours of Lum as the subs were a bit milky and adding to the noise. That was hard to do !

We now have approx 3 hours Lum, 1.5 hrs per channel RGB and 8x900s Ha.

I've really struggled to get the Ha to show up as a colour and in the end had to layer it twice after a quick discussion with Steppenwolf.

So, in effect we have here an LLHaRGB !

I'm calling it a day on this one before I overdo things and ruin it completely

Very nice

[Black Knight]

That's a great result Spikey, especially for your first attempt - I haven't even progressed to that yet! . Was this with your Atik 16HR?

[Spikey]

Hi Andy, yes it was with the Atik16HR, getting a bit more used to things now.

Gets a bit easier with LRGB second and third time

[Black Knight]

I tried LRGB with RGB binned on M97 I think, and it was a disaster! Sort of put me off! I shall have to give it another go, although I have other more pressing eggy-shaped star problems to resolve to first!

[Spikey]

My first attempt was horrendous and I felt like throwing the towel in. It's a learning curve alright.

[Black Knight]

Well I think you're getting there, so keep plugging away at it!

[Quatermass]

Great results Spiky I bet your well chuffed with that one lot of lovely detail in it as well,great job mate.

[Spikey]

Cheers QM, yes I am. Looks a bit weird on my screen as a jpeg, it's a lot better as a tif.

I've relented and just shot a load of flats so I'll be reprocessing this one over the next few days when I get back home.

Looks Brilliant Spikey now you've done the Ha.

[ollypenrice]

There's lots to look at in there. I think that the brighter parts would take some sharpening. I woudn't try to sharpen everthing, just the regions of strong signal. I'm sure your data has even more to give.

It was good to start with and now better still with the Ha Added

[Spikey]

I'm going to be processing this from scratch when I get home. The netbook isn't really the best tool for the job but it's not done too bad a job.

What's the best way of sharpening selectively? Couple of pixel high pass?

Fantastic result Spikey, a truely stunning galaxy image. Thanks for letting me coming and take a look while you were doing the collecting process
