In the spirt of Mega-Data, well, this isn’t. I have around 3.5 hour’s data. You know the blurb, its Messier 78, a diffuse reflection nebula in the constellation of Orion at a distance of around 1600 light years from us. The dust clouds are illuminated by two stars with the wonderful names of HD 38563A and HD 38563B. The object was a little dimmer than I first thought.
Imaged on the 19th of Dec 2014 from Heathcote, Vic.

Thanks Steve and Mike. Perhaps I should have pushed it a bit harder in the red. I know there is a bit of red floating about from Bernards Loop. It's a relaxing and soothing palette
A favourite of mine to look at (never imaged it yet!) and yours is beautiful. It's a very interesting part of the sky and your pic does it justice. Thanks for sharing.
Cheers
Graham.
Very nice Terry given it's quite a dim object and the small amount of data! I think the colours are good but as Mike said, a bit more red would be nice.
What's the extra diffraction spike in the bright star at the top of the frame? Unusual to see an artifact like that in only one star.
I especially like the ultra-fine dust-lane texture in the lower patch. Texture reminiscent of the Fox-Fur nebula. Perhaps an up-side-down pleased-with-itself cat's face, with screwed-up eyes. Nice.
Mike, I would like to assure you that no animals were hurt in creating this image. Thanks for the great comment.
Mark , thank you.
Marcus, yes, the mystery spike. I have been trying to determine where that is coming from. I believe it rotates in relation to the default secondary spikes. So, it must be from the rotator to image plane. The only thing that I can think is an OAG, but I am not sure. Look up through the guts, and I can’t see anything in there. Any ideas?
Rick, unfortunately, limited time that the weather gods allow, is all I have. After dragging all this stuff out, polar aligning, calibration, on a short summer’s night really cuts into available imaging time. We take what we can get.

Could be the OAG impinging on the light cone - not sure. Does the flattener rotate as well? I'd be taking a close look at it anyway. Even a spider web filament or a human hair on the glass can cause this kind of thing and both would be quite hard to see. Other than that ... Are you sure it rotates?
Ross, Thanks for the compliment. Only wish I had a little more data. Oh well.
Marcus, I cleaned out a few spider webs the other day. They really get in there. I would think that their webs would create a stationary spike. Everything from the rotator back rotates as one including the flattener. The secondary spikes are constant, and mystery guy seems to pivot with rotation. I will have to take everything apart and use those super doper magnifying glasses and a very bright light to explore further. To date, I have not been able to solve this.
Are you sure it rotates?
