Well it is good to be back on here. I found one or two datasets that I missed from before, one of which was M13 from pier 1. The interesting thing about this, is that M13 was taken at binning 1 as opposed to binning 2, and thus all the calibration files are not in the same format - they are all binning 2. So, I thought, I will have a go anyway. Obviously, I could only stack the light frames, which is what I did and hopefully it has come out ok... This was 60 blues, 60 reds and 60 greens, all at 1 minute long each. This equals an imaging time of 3 hours. Pier 1 uses an AD250 10" F/6.8 Dall Kirkham scope, from 656 imaging, and 10 Microm GM1000 mount and FLI ML-8300 Mono CCD 2x2 Binned camera. Thanks everyone and I do hope you are all ok...

thank you Peter for your kind words, I was quite pleased myself bearing in mind I had no calibration frames to use. You are a very supportive person and it means a lot. Just as an aside, I did send you a file or two that I was struggling to process, ones from my home here. You said you were happy too to look at them for me but as I have not heard from you about them, I was wondering if you had got them at all. I am not even sure I sent them through on the best email address for you, but if you are willing I'll be very grateful for you to have a look at them for me. I seem to have an ongoing issue to do with not being able to sort the gradient out and it makes life very hard for me from an astrophotography point of view. No pressure or rush anyway. Thanks so much. Simon

Great job on that Simon as well as the earlier Ngc7000 image. It's nice to see an unbinned image for the first time from one of these longer focal length scopes, as someone who a long time ago dared to suggest this on the forum as an option.

Would like the opportunity to use that scope binned 1x1 on a couple of galaxies. You appear to have managed successfully without calibration data, so well done.

Hope all is well and maybe when the skies eventually clear we'll get to see something from pier 13. I will do the same from pier 14 again once the weather permits. Just hope personally as I've sold my gear, that this doesn't mean from now on we get their clear skies and they get what previously were our cloudy ones!!!!!

Best regards,

Ray

Ray, so sorry for how long it is taking me to answer these days, but I am truly grateful for your support, as always. I also think that the images you have produced lately are super, with lovely blends of colour and so forth. You have brought out the details also and all in all that adds up to success! I am trying to keep my pecker up, and trying to pace myself accordingly. I trust you are managing too, as things do tend to wear one down these days - societally and personally - and sometimes one has an affect on the other.

Take care my friend and Happy New Year!

Simon : )
