I really like that - the tadpoles are showing up really well.

Well, that's different. I use PS and don't have anything else apart from more clear skies that the Uk. As for being a beginner, really, I think we in the most part we are, though there are some really top rate astro-photographers on SGL some of the stuff we see posted is truely stunning.

Great image and thanks for having a go, I have just shot another 3 hours.

Bed time,

Alan

No bother - it was fun to use data from a cooled dedicated camera - I only use DSLR at this stage.

GradientXterminator works really well in PS for removing gradients.

looking forward to seeing it with the additional data.

Hi Alan,

So here is my interpretation of your data. Its great clean data and I dont think I've done it justice (but remember I'm very much a beginner and I'm sure others could work it better)

I've got a bit of a "cinematic wide-screen" thing going on and I've brought out the blues, the ha and the details of the core more - because thats what I like! Not everyone does.

Anyway - if you want I can give you the linear tiff with just the gradients removed if you would like to try it further yourself - just let me know and I'll PM you a link.

What are you using for processing?

Hi Alan,

I'm having a lash at your m33 data but to do a Photometric colour calibration in pixinsight I need to know the imaging focal length ( after any reducer) and the pixel size of the imaging camera - Can you provide that and I'll get back at it?

Redone to try to reduce the saturation (as suggested by @ollypenrice and @Allinthehead - thanks folks) and also to bring out the dust more.

Lovely image,i had the scope on this last week for over three hours......or so i thought,when i got up around 4 for some reason every thing had closed down on the laptop after less than an hour.

Hate that!  I lost 5 hours from a 7 hour run on the Pelican to a dew heater not turned on a few weeks back!

Hi there - thanks for that.

Weather wise its awful again -two clear night last week and then closed in for the foreseeable - wall to wall rain for the last 48 hours.

Pandemic wise not much better - we are going int a full lockdown again from midnight tonight but just like last time there seems to be no real exit strategy.

Much the same for both up in the north I believe.

Take care,

David

C&C very welcome.

I think reducing the colour saturation considerably would give a calmer, cleaner image. Otherwise it looks great to me.

Olly

Thanks Olly.  I increased the saturation selectively in the dust right at the very end and that was a mistake. I really need to work on subtlety but I've never been much good at that.😆

Ruins many a good clear night.

 Nice Iris, maybe a little overcooked. I think if you try a more gentle approach to the process and work a little on the colour balance you could improve it. Sometimes less is more. 

Thanks for that. I think you are right, overcooked!  I'm just learning Pixinsight and I need to tone various processes down a bit. I'll give it another go at the weekend.

I worked hard to bring out the dust on this and I am not sure it really works that well - maybe looks a bit overprocessed? Comments and suggestions for how to make it better please.

That's a stunning image. Fantastic detail.

WHat a fantastic image!  Is this the type of filter you are using? https://www.firstlightoptics.com/light-pollution-reduction-imaging/optolong-l-enhance-narrowband-deep-sky-imaging-filter.html ?   I might need to ask Santa for one 🙂

Michael

Yes thats the one. There is a new one, the l-extreme which has narrower bandpass and is getting great reviews. But I have seen it mentioned that it may not work as well on DSLR (what I use). But you should ask around.

Thanks, that's something to start from. Can always download the trial version of APP and see how I get on. 👍

Personally I can't rate APP enough. It does a great job of stacking, it allows a high degree of flexibility for calibration frames, and the gradient removal and colour calibration are superb if you are taking them in to PS.

I'm new to pixinsight but have tried it for pre processing but I think i will continue stacking with APP

Lovely shot there. I got rid of my L ehance filter as I didn't like, had I have known you could do that I may well have kept it, live and learn.

Alan

Thanks Alan. Yes I know what you mean. I've not had mine that long and while I like the images I've done with it so far I've felt they were a bit, I don't know, uninspiring? But being able to take images with LP and even some moon made it worthwhile. And this adds another dimension to it altogether.

Thanks I'll take a look, I have the photoshop action set as well so I'll have a play around. Is the splitting of the channels done on the linear data? 

In App yes. I don't know if you can split channels in DSS. But in PS  I'm not sure what the best way would be. I'd probably do a first stretch to see what I had, crop, then pull the individual channel data at that point. But I've not done it so...?

Read to the bottom because you can do it without PI.

So initial splitting of the channels was in APP using the "extract Ha and Oiii" algorithms. Further processing was indeed in PI following this 

 BUT.. I'm pretty sure you could do it in Photoshop if you know your way around it. Copy out the R & B channels, work them separately using levels and curves. For recombine if you have carbonis actions that would work but if you are good with PS I expect you'd do it manually. Watch the video, and I'm sure you will be able to translate it to your own application.

Good luck and do post your result.

Continuing to play with this different way of processing L-Enhance data. This heart is from data captured a few weeks ago.

I really cant make up my mind about this - it feels strange producing this type of image from a DSLR - but I do like the colours in the images. Mostly!

Interested to hear your thoughts.

Great details and colour. An unusual framing for this target but i like it.

This is a first effort at a new -to me anyway- processing technique for data from the l-enhance filter. This involved extracting the Ha and Oii in APP, stretching out the Oiii data then recombining with pixelmath and using the Ha as a further luminance layer. Its fairly rough I know and I'll have another go at it to improve the overall image but purely from the colour perspective I  think its interesting.

thats a superp image. Fantastic detail and great colour.

that is outstanding - just fabulous.

This is a repro of an image I posted a few weeks ago. This time using starnet to allow work on the neb alone. Definite improvement in colour and detail - BUT (aint there always a BUT!!) something weird is going on in the stars now - looks like some type of chromatic aberration but it was not in earlier versions so I really dont know what happened here. Any ideas?
