Finally completed my SHO version. There is some purple in the image I cannot figure out how to get rid of and I'm sick of playing with it. Hints and tips on how to get rid of it welcome, I'm using PixInsight.

Thanks for looking!
Hello Astro Peeps, I hope everyone is all good! Isn't there some amazing images on this site and others. Amateur imaging has never been so good!
I myself have finally managed to get some data for an image, of which I am very happy. It has been so hot here it has been impossible to get any good data. One day a couple of months ago, I hung the thermometer from the grape vine under the back verandah and it was 47.5°C. Sounds far fetched, although true. I live in Adelaide, South Australia and we are 11km from the CBD and usually 1.5 degrees hotter than there!
Anyway, I thought I'd try my hand at a Ha, OIII bi-colour image while waiting for my SII data to come in. There seems to be a halo issue with some of the filters for which I will need to do further testing so I apologise for their distracting nature. Details are with the image but basically 3hrsx15min subs for each channel.

Happy photon collecting! ?

This will be my last image this season. The moon is all too bright atm, and astro darkness ends in a few days.
This image was a real challenge, both in acquisition and in processing. I haven't completely tamed the MN190 yet, collimation is still a bit off. Visually it looks ok, but when I start imaging, I get star shapes that suggest that collimation is still way out. First I thought that it might be the addition of an oag to the imaging train that was the cause of it all, but I've now come to the conclusion that it actually is collimation.
Anyways, the details:
MN190 on AZ-EQ6 ZWO ASI174MM-Cool at -20 C with ZWO filters Guiding was a mixture of ST80 guidescope, OAG (the new ZWO version), and finder guider (9x50) with PHD2 L. 92 x 2 minutes, gain 20, collected April 15 under a 70 % moon R, G: 30 x 4 minutes each, collected March 31 and during two nights in April B: 22 x 4 minutes, collected March 31 and during one night in April Processed in PixInsight

If anyone wants to have a go at LRGB processing, here's the raw data. Only crop and DBE applied. Have fun!
The Tadpole Nebula and the Flaming Star Nebula captured over three nights of the unexpected nice weather we had a couple of weeks ago.
A number of firsts with this image:
1. My first mosaic - keeping it simple with two panes!
2. First time I left my imaging rig outside... (I used a telegizmo cover) and it was perfect, allowing me to get imaging very quickly on each night
3. First time using powerful scripting tools in my capture software, APT, to move to the second pane and starting imaging automatically...worked really well!
APP was used for pre-processing and stitching the mosaic together, while Pixinsight was used for image processing. A total of 10.9 hours integration time.

A DSO image in planetary settings.
This is the Eskimo planetary nebula. Small as they are, this one has less than 1arcmin.
The image was taken with a C11 f10 and ASi224. No cut-off filter was used.
The capture was made with Firecapture and 2s exposures. The final processing was in PI.
