SMC in HaOiiiLRGB
Here's the (hopefully) final first light image from the AP140EDF last weekend. I collected some Ha and Oiii as well as the LRGB data on the SMC and managed to blend it all together in a way that I thought was pleasing. The narrowband data certainly shows a lot more stuff going on in the SMC. The LRGB image looks quite calm and serene but there's obviously a lot going on under the hood!
Details are...
Scope: AP140EDF/reducer = 771mm FL
Mount: AP900
Camera: U16M
Filters: Astrodon E series Gen 2 LRGB, 3nm Astrodon Ha and Oiii
Guiding: Lodestar / Borg 50mm guide scope
Image scale: 2.41 arcsec/pixel
Exposures: 21x600s L, 6x900s R, 6x900s G, 6x900s G, 7x1800s Ha, 6x1800s Oiii (14.5 hours)
Processing: PixInsight 1.8
The attached small image is hopelessly compressed. There's a large version on Astrobin:

The original LRGB version is here:

Cheers,
Rick.

Very nice Rick. Subtly processed which is nice for a narrowband rgb.

Thanks, Greg! I was trying not to go too overboard. The NB data adds some nice detail.

Hi Rick,
Although the original image is very nice, the HaO3LRGB version is IMO in a different league. A very well balanced representation of stars and nebulosity.
Awesome

Wow! As you say, there is a lot going on under the hood there. Enjoyed just flicking back and forth between the two images

Certainly looks quite different from the first image.

Ta, Derek & Paul. I was trying to emphasize the narrowband features but without going too far away from the RGB colouring. Not sure I was entirely successful but I wasn't disappointed with the result.
Cheers,
Rick.

Really like the extra detail and insights the NB provides. Showing the Ha regions nicely Rick without blowing the colours at all.

That's brilliantly done. Very subtle but bringing out the detail. Top job

Thanks, Mike! Plate solves were finding 80K+ stars which is more than I'd be able to count

Thanks, Simon. The quality of the data helped a lot. It didn't need much processing.

Simply outstanding!
I'm having issues with stitching mine; residual gradients along frame edges.

Very nicely done indeed Rick!
You've managed to walk the fine line between overstating and understating the Ha!
