Not missing in the sense of mythology. You know how it goes ...the Titan Atlas had seven daughters and because he was forever doomed to hold up the heavens, he couldn't protect them from the hunter Orion. So Zeus transformed them into stars. But only six were visible to the naked eye (for most folks anyway) so to explain that ... as the story goes ... one of the seven fell in love with a mere mortal and went into hiding. In my case that's not why there are missing sisters, though. It's because I haven't had the chance yet to do a mosaic. Actually, I haven't had the chance yet to do much of anything as far as DSO photography is concerned.
I have a lot of firsts here:
1. First DSO photography .Period.
2. Very first light with a new scope ... Orion [yep, that Orion and he's still chasing those sisters ... in a way :-) ] EON 130mm with a 0.8 Reducer/Flattener.
3. Very first time guiding ... and let me tell you, getting that OAG to work with the Orion scope was not easy!
4. Very first time using PixInsight to process the image. By the way, I'd like to give a big shout out to Mitch and his 12 part tutorial on PixInsight for beginners:
<a href="https://www.youtube....h?v=HIXJJqew6rQ" rel="noreferrer nofollow">www.youtube.com/watch?v=HIXJJqew6rQ</a>.
I only used the first eleven parts as I didn't do any batch processing ... just worked through each tutorial in order. If you're new at this give it a look. I don't think you'll be disappointed.
This is a product of eight (8) ... yes, eight ... 30 second frames, binned 2x2, taken with a ZWO ASI 294MC color camera. No Flats. No Darks. And No Dark Flats. Just the eight Light frames processed in PixInsight.
You might ask why only eight frames for a tolal of 4 minutes of Integration? The answer is the weather. The terrible, rainy, cloudy miserable weather! Hopefully it gets better.
