This is the first mosaic I have seen that I cannot see the join lines.

Many thanks. The issues I mentioned earlier are by no means limited to me, and would be experienced by anyone doing a mosaic over multiple nights. Though light pollution certainly makes it harder in terms of background brightness and colour variations. I spent a great deal of time balancing not just the overal brightness, but balancing the darks, mids and lights for each RGB colour in each frame. A lot of work, but essential I think. And it pays off in the end.

An example of this is the 'centre of the galaxy' image that Rob Gendler got an APOD (I often wonder about the selection criteria for that site) for and it had join lines all the way through it. It was obvious on a HD panel. too many people are still processing on CRT screens and it shows all the time. So for me this is a far better image. I often see join lines but not on this occasion. Congrats.

Yes I do everything on LCD screens these days. I only tossed my secondary Sony Trinitron CRT last week. When it comes to public displays (like web presentations) I think you have to go with what the majority of viewers are using. But LCDs certainly make it difficult when processing for printing. Even though everything here is calibrated and profiled (printer and monitors), the LCD monitors are still way too bright for my liking, so printing still involves some trial and error. Colours are great and accurate, but brightness is troublesome. I actually processed two completely different versions of this mosaic. One for printing and one for screen display using the appropriate profiles for each.
Many thanks for your comments!
