Күн бұрынSHO Astrophotography Image Processing in Pixinsight - Rosette Nebula Walkthrough
How to maintain great color, excellent detail, and pinpoint stars. The Hubble Palette can be a beautiful way to image the universe. If you use the strong signal from Hydrogen-alpha to keep the image clean, there's a lot you can do to bring the most out of your data.
I imaged the Rosette Nebula from Chicago with my telescope on Christmas night, and in this video I'll show you how I process the image to bring out all of the great detail and amazing different regions in this nebula.

Another great video. You really gave me some ideas to try in PI. 2021 for me was pretty good... lots of great images and huge improvement over my first year (2020). Looking forward to 2022 as I'm moving from OSC to narrowband. I can't wait... I really love the SHO images and it will make such a huge difference in my Bortle 6 skies. Keep up the great videos and images.

@@WindyCityAstrophotography thanks and to you too 👍 One area I'm struggling a bit is planning a mosaic in telescopius and matching the field rotation correctly on my redcat51, I use a efw and getting the correct angle is providing troublesome. Any tips?
@WindyCityAstrophotography 2 жыл бұрын
There is a comment on my Easy Mosaics Part One video about something that might be similar to this and I am waiting for a stretch of clear nights (ha!) where I can take some time to troubleshoot it. I generally leave mine at 0 or 90 because adjusting the camera angle on the RASA is a bit complicated. Are you plate-solving to determine the field rotation angle and then trying to match what you planned in telescopius?
@ScottDavies 2 жыл бұрын
@@WindyCityAstrophotography THX again and I will find the comment 👏 I will plate solve an image in my asiair pro to find the angle, I am attempting sh2-240 so I will do a test run of 3*10 minutes on Ha on each of the 2 panes just to be sure before I dive in ☺️

The Rosette was the first image I did when I got my 294MM and SHO filters earlier this year. I actually brought the data out last night to look at it. Of course, the first thing I thought was, "oh, that's TERRIBLE!!!" I'm definitely looking forward to targeting the rose again. Interesting that you don't do any noise reduction on the color data. That's actually the data I go pretty heavy on noise reduction. The convolution trick is a good one that I use occasionally as well :). Also, if you're just using the Ha luminance data for the stars, you'll have no color information for them, correct? I've never considered just dropping the single channel stars into the image... Hope you had great holidays, and 2022 is a year full of health, happiness and clear night skies :)
@WindyCityAstrophotography 2 жыл бұрын
Yes it is fun to look back on old data and see how good or bad it is 😆 Correct on the stars having no color, just a choice on my part and I have seen some great SHO images with wacky star colors that really work. When I get around to it (clouds!) I will take some RGB frames just for star color and put those in. Did that for my Wizard image a couple months back with good results

Like your videos as usual. I too have a ZWO 1600 color and would be curious if you could share a target or two where you shot both in color and mono. I would be interested to understand the differences.
@WindyCityAstrophotography 2 жыл бұрын
Thanks! Yes I only have the mono camera, but as far as shooting NB and broadband on the same target, my "Andromeda in HaRGB" video shows color data and H-alpha on M31. If the skies cooperate I am planning to do full RGB and at least Ha on M42, and Horsehead soon and hopefully M101 and M81/82 during galaxy season. I will definitely share that data as I am able. I did have some good success combining SHO nebulosity and RGB stars in my Wizard Nebula video too.

@WindyCityAstrophotography 2 жыл бұрын
Thanks! I could definitely use the other color channels on the stars and get some false color data (it can look really cool!) but not natural color. However at some point I will gather actual RGB data on the stars and insert that into the image. I did that with my SHO Wizard Nebula image for a video a couple months back

How big is your monitor? 😆 Like being in the front row of a cinema. Good for seeing those fine details I'm sure. Very nice colours too btw. 👌 How do you find manually changing filters on the RASA, not too overbearing? Can you add a rotator, and if not, how do you manage rotation?
@WindyCityAstrophotography 2 жыл бұрын
😂 Yeah it's a big monitor and too high currently! When clear nights aren't too rare I usually stick to one filter per night which simplifies things a lot with the RASA. But for quick SHO nights like this one or for a dark sky trip where I'm doing RGB it isn't too bad doing the swaps multiple times. Plus I have my flat panel settings dialed in for each filter so I can quickly grab flats without trial and error to get the right exposure. No rotator, generally I do 90 or 0 for field rotation to keep it simple, but occasionally I have tried for a more precise angle and then plate-solved in ASIAir to make sure it was close. A bit cumbersome to do the rotation with all the cables, but then again if I'm committed to that object for a bit and I don't have to remove the camera and reassemble it isn't a huge deal.
@emuhead 2 жыл бұрын
@@WindyCityAstrophotography 1 filter per night makes sense from an ease perspective. Hopefully Starizona or another manufacturer make a rotator thin enough, or even a camera manufacturer builds them in to camera collars. 🤞

Amazing detail given only one night of data. What is your preferred method for correcting magenta stars? Is that an issue when you only use the stars from your Ha data?
@WindyCityAstrophotography 2 жыл бұрын
Thanks! I generally invert the image color (which turns the magenta to green) and use SCNR to remove the green and then revert to true color. Voila! It is definitely less of an issue using Ha stars but I do it anyway so I can be sure the traces of magenta are gone before running starnet.

Can you show us how to do the process with a color camera. I have a asi533 and want to learn this method.
@WindyCityAstrophotography 2 жыл бұрын
Yes I will definitely do that at some point! It depends on the filter but you can separate some percentages of the RGB channels into their proper band passes and then combine/process from there with different weighting.
