Some processing under these clouds! I might add some OIII for a HOO version of this. I have been wanting to try a HOO with RGB stars, just to try Hope it doesn't come across as too noicy, but it's only 2h 20min. I finally got som flats, and used dark flats instead of biases after reading up on it. Looks like I have been calibrating these files wrong after getting the asi 1600mm-c... Now I stacked DarkFlats, Calibrated the Flats with the MasterDarkFlat, then stacked the Flats. Stacked the Darks without Bias calibrating, then calibrated the Lights with master Flat and master Dark. Looks to be working nice. @Unity and -25c asi 1600mm-cool 28x 300s Ha Lights 50x 0.2s Ha Flats 150x 0.2s Dark Flats 25x Darks Hope you like

Thanks Craig! I tried to restrain myself from over sharpening, and over saturating. Nice that you noticed

Tanks! Happy that you like

Full mon from Dec 1th 2020 in LRGB, my first OK moon with mono kamera and LRGB filters. Need to look into getting a 2x barlow to use with these full moon nights. For this integration I collected a total of 10.000 subs in the .ser format. At Unity gain and -25c i shoot 2.000 subs for LRGB each. I then shoot 2.000 L with a gain of 100, for a HDR L channel. All RGB subs was at 2ms exposure, and all L channel was at 1ms. Each .ser file was stacked in Autostackert!, then aligned using the FFTRRegistration in PixInsight. The L channels was combined with HDRComposision, then some curves and unsharp mask. RGB channels was combined, saturated and added to the L channel with pixel math. I then upscaled the image by 2x. Scope Equinox 80 PRO APO ZWO Asi 1600mm-c @-25c ZWO LRGB filters Everything controlled via EKOS and Indi ControlPanel, except FireCapture for streaming .ser with the asi 1600mm-c Hope you like, and Clear skies!

Nice 👌 Sure is a Pelican 😊

The brown wave in the middle is the Pelican neck. You are too close to see it You can compere with mine at a wider field. Mine is rotated 90 deg counter clockwise

New from Norway's (only private remote obsy? [not sure]) Anyways. I feel I'm re-learning some processing skills with PixInsight after a few seasons with little light collected on my part. I guess it is still a little noisy if you enlarge it, but to me it looks good at the moment. A v2 is never impossible, but need some feedback on the current situe. All subs are 300sec @Unity and -25c with the zwo asi 1600mm-c At the moment calibrated with darks and bias, but will try to move on to darks, flats and dark flats, as I understand this is better for my CMOS camera. Also available on http://observatory17b.com and my album https://stargazerslounge.com/gallery/album/4302-observatory-17b/ Hope you like If you have any pointers to v2 down the road, then don't be shy. Clear skies everyone 🎅

So this is my best Andromeda so far. Possibly my best galaxy image, even tough there is room to do better 😎 Camera ASI ZWO 1600mm-c, ZWO LRGB filter, Baader Ha, Skywatcher Equinox 80 PRO APO This is all @unity and -25c Bin 1x1 we have 24x 300 sec L 2 hour 24x 75 sec L 30 min Bin 2x2 there is 24x 150 sec Red, Green and Blue 3 hour 24x 45 sec Red, Green And Blue 54 min 14x 150 sec Ha 35 min Totalling 6 hours and 59 min. Most of this collected on 19.11.2020 and the rest on 21.11.2020 If anything, I should have collected a little more Ha. Anyways a fun project to do. Hope you like, and Clear skies 🥳

Thanks Carole. I've also landed on the second set. One thing I have noticed on images with stronger color is that the smallest stars can be over sharp, and over saturated. I think it is because the making of the mask for star masking, often leaves out the tiny stars. So they are exposed to different types of sharpening. When they are then saturated, they can be a little harsh. Usually not easaly noticable when viewing the image from a distanse, but I do like diving into the details on my monitor

Hmm. I don't like images over-saturated, so I tend to end up a little under-saturated. I tried upping the saturation a fair amount, and I think I like it better, it POPS more. Witch do you like the best? v1, or v2?

Thanks Its only my third 'tri/full' color NB project to date, so I'm happy.

Uploaded my result to the dso forum https://stargazerslounge.com/topic/365810-elephants-trunk-nebula-ldn1099-in-sho-11h-integration/

Just got to the stage of v1 completion of my most recent image, The Elephant trunk nebula centered on LDN 1099 This is a SHO (HST) image composed of 2h 45min SII, 3h 39min Ha, and 4h 45min OIII Imaged at my remote 'linux/Indilib' box observatory ' observatory17b.com ' over several nights. Camera is ASI ZWO 1600mm-c cooled to -25C Scope Equinox 80 PRO APO. Hope you like, and let me know what you think Clear skies

+1 for easy fix 👏

Thanks!! That gave me a lot better starting point to get what I'm after

Are you sure? Are there different ways of inverting the image? I used IMAGE -> Invert, and got this.

Hi. It has been a long time with little imaging for me, so the basic Pixinsight skills I have is a little rough at the moment. I have been imaging the Elephant's trunk nebula and I'm now up to a 11h 9min integration. I have processed the Ha data to a monochrome image I'm happy with, can be seen here. https://stargazerslounge.com/gallery/image/36330-elephantstrunk_ic1396ldn1099-ha/ However the color version is not to my liking. I really like the more gold and blue looking HST images but I'm not getting that from this. My previous HST image was the Monkey Head nebula, and I really like the colors from that image https://stargazerslounge.com/gallery/image/32303-monkeyhead-ngc-2174-shohst/ One of the images of the Elephant's trunk on the wiki page is around the same amount of image data, but with a lot nicer colors. https://en.wikipedia.org/wiki/Elephant's_Trunk_Nebula#/media/File:Elephant_trunk_Ha+OIII+SII_Hubble_palette_modified.jpg So here is what I got so far. 2h 45min S2, 3h 39m Ha, 4h 45min O3 First one is RAW color from pixel math. R = S2 *1, G = Ha *1, B = O3 *1 And here are two examples at trying to process the color data. Not sure if I have to get more S2 to get the colors right? Should be possible with what I have, the S2 data will only be a little noisier? And the cropped and streched stacked images.
