I’ve never really used PixInsight for processing -I’ve always stuck to processing in Photoshop where colour balance can usually be sorted using a mixture of levels to balance black and white points along with Gradient Xterminator to get a uniform background. That’s always worked well for me. Comparing to existing images of the same target might also give an idea of how others have balanced out the colours before you go down your own route. I think it just shows the value of processing an image more than once. I tend to do a rough first go at it to get a feel for the data and ways of bringing out details, before going back to the beginning and doing it all over again with what I have learned first time round. The difference from where you started to now is really telling. I would say any further might be over-processed, I hope you are happy with how it turned out!

Yeah, looks a lot better. Might still need a bit of reduction in both blue and green levels for the background. At this point, is likely more down to personal preference rather than science but its still an amazing image regardless

Brilliant picture, the pinks look really natural so I think your “random” addition has worked. It might be my monitor but I think the background is a little green? Might be worth adjusting the background levels to help the colour balance.

Once APT is underway on an image plan and guding is solid, I get a deck chair out in the garden, recline back and just take in the stars. With hot chocolate in hand it becomes a really relaxing time to be with my own thoughts.

Will be great when JWST follows up with this. Amazing if it is truly a single star keeping in mind galaxies look like a small smudge at that distance in Hubble images.

I would say it is overdone in terms of the galaxies, but I don't think that is something you should worry about. Getting IFN to come out is a huge challenge unless you are at a dark site with long integration time, so it’s still a stunning image. One idea is just process it twice. One time to maximise IFN, then one time just focused on making the galaxies as good as possible

Looks like it as the bottom of the picture will be closer towards the ground imaging at that orientation. Although it costs, gradient XTerminator has always worked well for me to flatten the image and get a rough colour balance as well. A free option (but more basic) is to use the colour range tool in photoshop and then use it to select only the lighter part of the image. You could then use levels/curves to balance out the brightness difference. The image as well would always benefit from more integration time. 1 1/2hrs really isnt too much and imaging with a dual pass narrowband filter would help bring out the contrast as well with the nebula. 5 mins is a really long exposure time to be using as well. Even with a narrowband filter I was using 2min exposures to stop blowing out Alnitak.

Agree, visually you are most likely to be looking at an object in the centre of the view only, where coma is never an issue- this is why people don’t really consider it necessary for visual stuff. Different story for imaging where the corners of the image have to look perfect as well.

Agree, looks like the wall and pelican are giving each other a staredown before a fight Whole picture looks great, starless helps bring out the contrast as well.

I had the same concern when I was imaging in my front garden for the Orion nebula with no light pollution filter, pointing nearly right at two LED bright streetlights. In the end the final picture was one of the best I had done and you wouldn’t have known that it was almost shot in bright daylight. I did most of the setup of the scope without a headtorch it was that bad. One reason I think I got away with it was using a dew shield. It has a nice secondary purpose of blocking stray light, so even if you can’t get the lights dimmed/removed then all is not lost. Otherwise, stick to imaging high above the horizon and narrowband if possible.

I started out imaging with a 200p/EQ5 mount combination. I honestly wouldn’t recommend it for astrophotography. It’s perfectly possible, but you will have to manage a lot of issues that take patience and a lot of trial and error. Even then, you still won’t be able to get the best results. If you do plan for imaging, HEQ5 is a minimum for giving yourself an easier time, although it does take time to learn how to use the end result will be better. First priority would be to have a go at some visual work to get used to the scope and check the optics are up to the job. Collimation of the mirrors would also be needed.

For the astronomy equivalent of plug and play, that is not bad going at all. That moon picture is sharp for a single frame but it does struggle with the dimmer nebula. Still not a match for a "true" deep sky setup, but the gap is closing I feel with what is possible out of the box.

I'm just imaging golf style commentary now over an imaging session and its starting to catch on in my head haha. But I do think its a good plan. getting people interested in space starts with doing simple things like this and showing them whats possible from your garden. Combining imaging with a visual scope, binos and naked eye viewing cant do any harm. Tell them to wrap up warm beforehand and have some warm drinks on tap as well and it should make a great night.

"Oh wait, no- think I messed up the colour balance on one of the layers, need to delete 5hrs work and start again, is everyone still.... hello?"

I've been considering the same recently, problem is I just don't think astrophotography is much of a spectator sport. Most people's enjoyment starts and ends when it comes to the final polished picture but they don't really have much more than a passing interest in the technical stuff and hours of sitting around that goes on behind the scenes. Sure, scope slewing and platesolving can look cool but then sitting and talking through guiding errors, filter choice and polar alignment in the freezing cold will put most to sleep, compared to other astrophotographers that would talk all night about that stuff. Your best bet could be to have a dual setup going, talk them through the imaging side and have that running in the background, but also have a visual scope to show them the real stuff as well- then you can give the finished picture the next day as a memento. Have some deck chairs so you can lay back, look at different constellations and watch for meteors. Combined with some drinks it gives a bit more variety to things.
