Cone closeup

[assouptro]

Hi starfolk 

I nearly didn’t process this or post 

I didn’t get nearly enough sii and oiii to satisfy the Atik383 but I thought I’d have a go anyway as it’s always good to share your info to help anyone thinking about imaging the same object 

its 9 hours Ha

4 hours oii

3.75 hours sii 

scope: 12”Meade sct Starizona lf field flattener/reducer 

Mount: skywatcher azeq6 

Camera: Atik 383l

Filters 1.25 Astrodon 

process: astropixelprocessor, Pixinsight, Photoshop, ps Express 

It’s a bit of a crop 

Anyway…..

 

Thanks for looking

That is so good. I can only dream of getting an image like that.

Thank you for the comment 

There was a time when I would have felt the same, and I still do when I see some of the amazing images posted on this site 

Thanks again

ooh yes.  Thats lovely.  An object like this deserves a close up.

I really like the detail in the pillar - shades of black ! - and also the little chap's eyes and teeth at the top of the cone.  I could see them in my Ha image but they got lost in the jumble with the other filters.

If I can ask - what was your recipe for the colour palette? and how do you do it?  My HSO of this ended up a lurid red and yellow - which I actually quite like, but it would be nice to have a choice!

Thats one great image! Love it. It will be a very long time before I can hope to get an image like yours but the journey continues 🙂

Hi Simon 

After stacking the individual filters (in astropixelprocessor) I opened them in Pixinsight, applied blur terminator to each sub then combined them sho which came out green (as usual) I then applied scnr in pix to remove the green, the colour at this point was quite muted but not too dissimilar to the posted image 

I then used curves to alter the colour balance a bit 

I then stretched using eztools soft stretch 

Saved the file, and opened in photoshop (cs6) where I applied a 10% luminance layer (ha) which I blended at about 20% opacity

I did a couple of extra things that I can’t quite remember, but the colour was tweaked in photoshop using a selective colour layer blended that in and did it again until I felt happy 

uploaded to my phone using OneDrive then used psxpress on my phone to tweak the contrast, sharpness, and colour balance again to make it look a bit cleaner 

Something like that, roughly 

selective colour is a great tool for altering the colour balance 

This could be useful?

That's superbly detailed. Nice to see a DS image from an SCT for a change, too. It certainly works!

Bryan - Thanks for the instructions !  I will have another go at my Cone closeup...

Thanks Olly 

I’ve been mainly imaging with my 12” Meade for about 12 months now. Although I have quite a few scopes to play with I have really enjoyed the closeup nature of my original “serious telescope” the challenges it throws up and it’s predictable nature

I hope one day to own a mount that will help me retain more usable subs, or a camera that doesn’t need 15min per sub to reveal the signal 

Thanks again for the comment

You are welcome 

I am looking forward to seeing your revised image (not that there was anything wrong with your first!)

Hello Bryan - here is round 2  (well, more like #35!)  A very instructive process trying to rework data in a new direction.

Simon

Whoa that is right up in the top tier.  I much prefer the first image!

Hi Simon 

Really nice work!

It’s difficult to flick from your old image to your new version for comparison whilst viewing it in my thread but I can see a lot of work has gone into colour control, sharpening details and star reduction! 

I’m impressed! 

I did like the dynamics of your first version as you had quite a lot of data, maybe you could try a combination of the images? 

Just a Suggestion? It’s all practice! 
Thank you so much for sharing your hard work 

cheers

Good point!  Here is before and after. After your recommendation I added BXT and SCNR to the toolkit.  BXT in particular is a revelation...
