Nice Doug. Looks like you got there in the end. Sounds like the smoke affected subs might have been your pay-back for not suffering enough in the cold outside......
I made a coupe of mournful attempts at M16 late last year, but I must have another crack at it (if I can brave the cold ) after seeing your results. Nicely captured and processed ... as usual.
Nice image Doug. I generally aim for 15 shots to get nice depth to my images. I don't always get 15 of course but I always set it for that.
I think you might want to address the slightly oval stars though. Is this flexure or is the camera slightly off from square? It is not much but I reckon you would see it in the full size images a fair bit. In the end it is the minor things that start to matter once the basics have been mastered.
Thanks for all the comments. I seem to have some form of guiding problems that I don't seem to be able to quantify. Some times things just go all over, other times PHD just locks up and requires a full restart.
I really don't seem to be able to pin it down at all. The small variation in star shape seems to be the result of some of these problems. Sometime I will manage to work out this problem and get it working better although guiding at 1800mm is at best dificult.
Thanks again.
Tis a nice shot Doug, I'd be *happy* with that. Pity about losing so many subs, but I'm sure you'll grab more later and re-process.

Thanks Dave, I doubt I will add to this one. With the elongation of the stars and problems I had with this one I think the next image of this target will be a new one with a few things a little better. ( Not a fan of Repros', once done best left.)Unless the original data is excelent.
