My joy was short-lived. This morning M57 has reverted to reversed colours (blue outer and greenish hue inner) no matter what selections I make. I will re-learn the sequence in case I have messed up but the result is once more fully repeatable.

Oh - or rather OMG! Thats done it properly! I should of course have said M57 not M27. As mentioned I was using an older version and found myself in deep water. I will seek out the videos on the main site. I had looked at some previously and even made notes. One problem that I have had has been ident...

Are you using Open to load a single fits file, or are you using the compose module to load the three channels from your fits file? Note sure if what you are trying to say is that the compose module has frozen locked and you can't cancel or just continue using it. The situation is this: until a day ...

:) I am considering a tri band filter, though unless I dig out the barn door I am limited to 30 second images which may not be enough for such a filter. Honestly, I've been rather impressed with the datasets I have seen so far. It doens't appear much ('important') signal is lost for objects that pr...

Hi The image stays B/W until the colour module is used, this is as expected. I am not following you with the Compose module comments. The module icon stays lit as it is a module, and some modules are available to use all the time and others are dependant of whether tracking is on ot not. If the Com...

Help - I can't escape it! I suddenly noticed that after loading my usual M25C OSC picture of M27 it appeared in b/w. Then I noticed compose mode was switched on. It could *not* be switched off! It did not toggle but entered a new mode when clicked. I don't want 'compose' mode - but it won't let me e...

I am hoping that including a sample image from the processing might stimulate some kind soul to help with advice on this query. My puzzle: what colour selections should I do to get nearer true colour when using a multi-band filter with my M25C OSC camera?

TIA
