I still prefer to keep it on the grainy side rather than the waxy side, but it's a fine line

Cheers Lee, 100% can see that now, definitely looks better. I am finding HLVG removes too much green (if that's a thing) and leaves it a bit on the magenta side. How did you remove the magenta?

Damn fine that, would never have guessed it was under 1 hour per panel.

Some job David. Nice colouration choice, lots of nice fine detail. Beers can definitely help 😂

I’ve both mono and colour cameras, also have limited clear nights, but still find mono has an edge. I’ve shot pure 3nm narrowband with OSC as well as the dual band filters eg NBZ, and whilst it is close, the mono camera is better at it (as expected).

Thanks! Definitely works well, it’s a good arrangement for sure. The colour data on its own is great but the luminance is very nice and much sharper.

Thanks for the comment! I did indeed Stuart, I stacked it all in APP and then opened the linear data in PI and ran BXT on the standard settings. I then opened that fits in APP again and did a stretch and saved as a TIFF.

Thank you, appreciate it.

Lovely version Adrian, the starless version is really something And a sensible idea combining your data. More to come hopefully from you both? Adam.

Looking great Rodd, a nice solid version of M45 with all the good stuff. Happy Xmas Adam

Here is my image of M45, data taken over two sessions - the evenings of the 12th (79% moon) and 19th December (21% moon) Scopes: 2 x APM LZOS 105/650 Cameras: 268M / 2600MC Mount: Mesu e200 Guiding: OAG / 290MM Acquisition: SG Pro / PHD2 Misc: Pegasus Power Box Advance / Atik EFW3 / ZWO Filter Drawer I used a total of 15120s of luminance and 11400s of OSC data, taken with 268M and 2600MC respectively. Total integration time of 7 hours and 22 minutes. Stacked in APP, processed using Pixinsight, ImagesPlus and Photoshop 2023. I think it holds up ok at 100%, which is always my aim when processing, so I tend not to push it all too hard. I had a look through the background and these is some amount of small galaxies littered around even with a little bit of detail/colour in some edge on and face on spirals. C+C welcome as it still feels a bit more trial and error in the later stages, wanting to improve as always. Happy Xmas! Adam.

Yes that’s exactly it. However your flats are very short. You may as well just calibrate with a bias frame instead. My flats vary from 1s to 20s depending on the filter being used. I would recommend you decrease the light source output to make you flats a longer duration.

I recently got a Pegasus box, and it’s working perfectly with two USB3 IMX571 cameras attached so you won’t be disappointed 👍🏼 I use my ZWO camera to run an OAG via the usb rear ports, hasn’t given me any trouble in almost 2 years. It’s the one feature I miss not being present on the QHY equivalent.

Whatever length your flats are, you then take dark frames (scope covered) the same length of time. So for example if your flats are 1.35 seconds, then you take a set of darks that are 1.35 seconds long - these are your ‘dark flats’

Do you take dark flats or bias to calibrate the flat?

Beautifully done, what a great region of the sky with the jewel NGC1333 in the middle. This has a wonderful 3d feel to it.

Love it! Subtle and striking.

Thanks Olly. Very useful thanks

I have decent skies where I live, at the lower end of Bortle 4 and I can see an appreciable different in the quality of broadband data under a full moon. I would be one of those who thinks twice about imaging under a 100% moon. I think when you are used to good conditions, it's hard to get motivated to collect data under significantly unfavourable conditions. I would however use narrowband under the moon and keep away from it as so far is possible.

That is a really fantastic result. Does the moon add much to your Bortle 8 site light pollution? I think imaging in the full moon is possible, but it needs a lot more data.

YEAR 4 learn pixinsight 😂

Mine are the same 2600MC

Thanks for sharing this workflow Olly. I'm not 100% what this means though, done using curves? and how do you know what 80% is? Thanks

Great job there Dafydd, nice progression of improvement.

Get it close and let software tidy it up?
