blinky

This seems like a gamechanger! The original was me messing about four an hour or so, NR, sharpening etc, to be fair I think there was more I could have got from it, it was a quick process but..... For the new process, I just ran NoiseXTerminator then BlurXTerminator and combined the channels and stretched, thats it! After: Original:

ran the raw linear channels through NoiseXTerminator, then BlurXterminator, then linear fit, then noticed I needed to run ABE on the O3 channel, did that, combined them, stretched them and thats it. Nothing else, wow what a difference!

Im hoping to get more out of this but was also hoping for it to be less noisy right from the start! I got 60X5min subs in each O3, S2, Ha channel, so 5 hours each/15 in total. The scope was my F4 newt and the camera was my ASI1600mm, maybe Im expecting too much! the sky although clear was not that great, guiding was over 1arc sec all the time and with this settup giving 0.98arcsec/pixel that probably the cause. Im going to run deconvolution on the individual channels later and give it a proper process, not a 'Im working from home, lets sneak to my laptop and process my image in 30 min' process!

lovely image!

I bought a used, what I thought was eq6 puck but it doesn't seem to fit. Are there differe t styles of these available depending on the age of the mount?

my existing one is fine to be honest - just getting a bit old, its a gaming laptop so very bulky and the trackpad is starting to flake somehow now as well, which is my real reason for the new laptop

just thought to check the pixinsight benchmarks! my current laptop got a CPU score of 7979 when I ran it and looking at the benchmark site, the processor in this new laptop scored 19,889 so well over twice the score! I am now assuming this is defiantly a faster laptop!

Im thinking of getting one of these : https://www.currys.co.uk/products/asus-vivobook-pro-m3500qc-15.6-laptop-amd-ryzen-9-1-tb-ssd-blue-10230046.html At the moment I have a relativly old gaming laptop (Origin) with a Desktop Intel(R) Core(TM) i7-6700K CPU @ 4.00GHz and 332GB of RAM. Obviously this new laptop is half that but I think 16GB should still be plenty for Pixinsight, my worry is the laptop wont be any faster than what I have. This is the spec from the site: Graphics card - NVIDIA GeForce RTX 3050 - 4 GB GDDR6 RAM 16 GB DDR4 Processor - AMD Ryzen 9 5900HX Processor - Octa-core - 3.3 GHz / 4.6 GHz - 16 MB cache Storage 1 TB M.2 SSD Screen Resolution Full HD 1920 x 1080p Screen size 15.6"

Thanks for the comments, yeah I was thinking about a double process then maybe try and blend the galaxies back in

This was taken at the weekend at my mates cottage just outside the Galloway forest - Not sure if I've pushed it too much to get the integrated flux to come through? Not something Ive managed to really capture before, so at a bit of a loss as to how to process.... I think the galaxies look over done, happy for any thought & comments M81&M82.tif

Heres my entry, 3 pane mosaic from the Horsehead to the Orion Nebula in Ha. 20X5 min subs for each pane and an additional 20x10s for the core of Orion. Taken with ASI1600mono and ZWO Ha filter with a WO ZS73 and EQ6.

Yep, got it all sorted, really pleased with it, shame I will probably need to wait till next winter to get O3 and Sii but this is looking not too bad! I managed to do it myself in Pixinsight and also added in 10s subs of Orion nebula as well as a restack without the place which was messing up the flame/horsehead region a little.

Yeah dunno why I didn't think of that! I need to restock the horsehead without the plane and I also have 10s subs to go in the horsehead as well.

Cool! Dunnon what Im doing wrong, any chance I could PM you my email and you could look to transfer the file to me as a fits so I can process it further?

I've got 3 stacked Ha images that I want to turn into a mosaic. I have stacked and Mure Denoised them and the next step I thought, would be to linear fit before turning into a mosaic.... When I try and run linear fit on them I get the results below, I choose the Horsehead frame as the ref, the drag linear fit on to the other 2 images. The bottom images are the results of this once I then apply the same stretch as the Horsehead frame - any ideas? And any ideas how to sort???

What is do is linear fit the rgb channels then combine and stretch, then stretch the lum and finally do LRGB combination by replacing the RGB L with the actual L data

Yeah I do stretch them prior to combining, is that the wrong way round to do things?

Think I fixed it - but have also added fits files BaseLUM.fit BaseRGB.fit

I think this is due to the L channel, but the bright stars in my M45 image seem to be very grey, the screenshot below shows this, left is L, middle is RGB and right hand side is LRGB. You can see in the RGB image the star look OK, Ive not pushed saturation or anything here, just a combine of RGB and a stretch but it does appear to have colour, the LRGB image just shows grey round the star. Ive attached the individual stacks in case anybody can help. BaseLUM.xisf BaseRGB.xisf LRGB.xisf

Seems it is faulty, it's missing a part on the bottom of the sensor so it's going back!

Hi, I bought a spyder3pro from fleabay that arrived today. I activated the version 3 software and ran through monitor calibration.... my monitor is pretty good to be fair but when measuring with spider it showed the green as really, really low. Running through the auto calibration it then produced a horrible colour profile with green cast as well. I've never used monitor calibration hardware or software before, it looks like this might be a faulty unit I've bought 2nd hand but anybody able to confirm/assist? Im not sure what else I can try.....

Brilliant - thanks for doing that and also providing the details of how you did it! Will go give it a try myself. Cheers

See the image, my monitor seems to show grey images as brown, the right hand side is my laptop where to me the colour looks more grey. I've played about with the windows settings but cannot get it right. Anybody know anything I can try?
