The first two paragraphs are just me needing to vent, so you probably want to skip them to the actual question in the third.....
The last couple weeks have been a bit of a slog; a conjunction of unfortunate events. Bad weather, short nights, and bright moon (when the weather wasn't bad). The learning curve of adding guiding for the first time (OAG). The complication and hassle of getting all the right adapters, extenders, and spacers needed to add the OAG. First time through putting it together, binding and bending an extender that put everything on hold waiting for it to be replaced. Getting it all together, finally, to discover I really needed parts with a wider aperture (and a much wider price...) due to the vignetting what I got was causing. A collimation attempt that led to a loose and spinning secondary mirror assembly, which in turn, but indirectly, led to an 'advised' shift of the corrrector plate (advice I followed, but still not sure if advise-able....), and finally a clear night that, to my novice eyes, looked really good.....until the next morning when I pulled up the images and......questioned everything.
Then last night it all came together. Completely clear, and all indications that the seeing was much better than the previous night. My polar alignment was.....well, not terrible, PHD2 was, for the most part, willing to put up with me and my mount, I checked a couple of the first images on my camera screen and they looked really good, so I got everything going, went to bed, woke up after a couple hours to change the camera battery and check all systems, and woke up again before dawn to pack up and minimize dew issues. Did another spot check of a couple images with FastStone before heading to work, still looked good and congratulated myself all day, got home, opened up Pixinsight and loaded a random image and.....it opens in color.....which it's not supposed to, until I glance at the title and see .jpg.......and on further inspection, it's my camera's smaller jpeg format to boot......somehow the file quality setting was changed and I didn't notice. I blame BYEOS......probably an act of retribution for doing my PA and then shutting it down to use a simple intervalometer to run the imaging instead....
Anyhow, I have about 30 of them, so a small stack, but will be getting more, and raw files going forward. My question, is it possible/advisable to combine the jpeg's with future raw files, or do I just stack them alone as sort of a preview to the main event?
Cheers,
Scott
