M45 colour balance
Well here's another query back to back on my last one. Things have piled up since I haven't visited the forum for so long :) I took this image with an 11 inch RASA f2.3. I think there is about 88 min of exposure with 4 minute lights which is a lot of exposure with such a scope. I was amazed to see t...

Re: true colour in globular clusters
Sorry, I've been away for a week or so and won't be back for several days. I will post a Dropbox of my stacks and I'll also restack them with a different programme though my m13 looks the same (used with a different scope and osc ). Looks like Ivo may be away or busy but I'd love his view on this as...

Re: true colour in globular clusters
So I tried copying the information from the log of prior rgb images, applied and got this https://www.flickr.com/gp/rkonrad/74Pw0t51je.
Now too blue. I would love to hear Ivo's take on this problem if he has time.
Thanks! Richard

Re: true colour in globular clusters
You did a lot of work Mike - thanks! I've used this scope a lot as it is one of the "free" scopes at Itelescope. Here are few other rgb images I took with the same setup. https://www.flickr.com/gp/rkonrad/06RT3ZPee4 (2 pictures). Did you want to see all the light frames or just the stacked one? The ...

Re: true colour in globular clusters
I had the exact same problem with m13 some time ago. The scope is a 12.5 RC with RGB filters - taken in Australia under nice dark skies. My guess is that the field of view does not contain the wide variety of stars needed for a proper white balance. I can forward the data to anyone who would like it...

true colour in globular clusters
Hi all Nice to return to the forum after a long time. I've recently imaged 47 Tucanae - globular cluster and found that scientific colour was not able to give the stars the correct colours. In a case where there isn't an evenly balanced variety of stars, how would I achieve the proper white balance?...

Re: NB Accent - multiple data
Mike, I tried the Siril option you described and all I got was a black image. Perhaps I didn't do it right. I'll try again though thought I followed your directions carefully. Anyway, I got impatient and used the blend tool to achieve a balance between rgb and bicolour. Here is my try. https://www.f...

Re: NB Accent - multiple data
Thanks for the suggestion Jochen. I did try it and the software wasn't able to tell what was color - just monochrome.
