Great preview H I am sure this project will turn out majestic, it takes a bit of b@lls to start "proper" imaging (as per your statement) with such a big project

I have a project running on the same area with 12 panes that started last year but have to say that I am unfortunately at a dead point at the moment, properly merge so many panes (in particular colors) is a very hard task, so you have all my appreciation in this one

Hi H,

What is your workflow here? Do the luminance first and then align the rgb colour panels onto the luminance using Registar one at a time?

If you have the luminance stitched nicely then the colour may go on a lot easier as its more the gradients that seem to cause grief in mosaics.

PixInsight came out with a gradients for mosaics module some time ago. That may be very valuable for this kind of work.

Greg.

Louis,

Hey, cheers! Good to hear from you. Hope you've been making use of those dark NT skies.

Marco,

Thanks, sir.

I guess having such a wide field with the FSQ makes it hard to go after small objects (my real love is long focal length), so, got to mix it up and do something interesting. I look forward to purchasing a long focal length scope in the future.

I remember you mentioned ages ago that you had started on a mosaic but were having equipment issues, as well.

Hi Greg,

You're part-way correct -- no need for Registar. I do everything in PixInsight.

I took 8 reference luminance frames that were just 10 seconds long each, after having built the mosaic template in TheSky6. These are what I run MaxIm DL's PinPoint LE plugin on each time I go to start imaging. Sync the scope, re-goto centre of solved image. If it now looks bang on (or, close enough to being bang on), I start imaging.

For this iteration of the image, I took Rogelio's advice and tried the GradientsMergeMosaic module. Absolutely fantastic.

Mosaics are such a time consuming process that make you want to tear your hair out. I've only got 1 hour of red bin2x2 on panel 1. I don't know when I'm going to finish this project.

Still, something to look forward to.

Cheers.

Thanks, all.

An impressive image to match your ambition, H.
Inspirational to say the least.
