NGC6188 in Ha at 3900mm.

[pmrid (Peter)]

This is a predictable subject to image but I wanted some strong Ha to test the new ATIK11002M. And also, I wanted to test my new OAG setup with my EdgeHD14".

I had been plagued by elongated stars when using a piggy-back guiding rig and run out of things to tighten or tweak. So I decided to try to guide at a FL of 3900 - not easy and finding a guide-star problematic but here is 90 mins worth of Ha and 50 mins of O3. That's all I could manage before my Dec motor started to stall. (It's always something.)

I have not stopped yet to ask how to process this data so I've just stacked them in DSS and pushed it around a bit in PS.

The real message in the images is about tackling the elongated stars AND showing that an EdgeHD14" can illuminate a sensor this size (43mm diagonal).

It's like a gigantic celestial wave is about to come crashing down on us.
Beautiful!

Great to see you got a result Pete.
Ken Crawfords Tutorial on Clipping Masks and Colour Mapping is worth a look as is this page on the hubble palette.

Nice images Pete,Looks like the OAG setup is working well

Not bad for such a long focal length (and for a guy with a chimp for a head )

How long were the subs?

Can you post a larger file?

Got a picture of your setup?

Am I asking to many questions?

Not bad? LOL. That's freakin' awesome Peter. Best close up on IIS to date I reckon, by a long shot. Well done. Got that guiding nailed too. Inspiring stuff.

PS: played with your data and did a quick combine. It will really shine when you add Sii.

Its looking good. You must be happy getting a result like that and everything finally starts to come together.

Greg.

That is great detail at that fl will be wonderful when complete.

You need some surf music to go with that, Peter. Wipeout, perhaps?

A great result!

Cheers,
Rick.

Long live the Shadows.

good results, big focal length

[RobF (Rob)]

Yep, that's an awesome debut Peter. I love the combined image Marc has come up with. Just wonderful. Great to hear its coming together for you.

Hi Peter,

Amazing detail....amazing focal length!


Thanks.

Thanks Marc. That's very kind of you. I did manage 2 hours of S2 last night so I'll be playing with that extra data today.

Just saying it as it is Peter. Looking forward to more stuff from you. It's a killer rig.

Hi Mike,
the Ha and O3 were all 10 minute subs but the SII I did last night were 20 minutes - got an hour in before seeing deteriorated too much.
I attach the SII stack to see if anyone wants to have a play with the Ha anf O3 I posted earlier.
And, as requested, here's a pic of the rig.

Here's my shot at it. Had to scale the Sii a bit. Your post was smaller than the two other channels. Still a corker though. You should aim for the prawn next.
