While Ross was shooting the pleiades I did a lot of panels in no particular order of the milkyway. This was shot with the SONY NEX-5 35mm stepped down to f5.6. I used the polarie so these are 3 min single exposures stiched together with registar and blended with PS.
There's a full res here that yields some details. The original is here [13.5MB]. Incorrectly labelled 55mm.
I'm trying to plate solve the whole thing but haven't managed to yet. Will amend the post when I do.
I also have a Ha version shot with the QHY9/35mm which I'm still working on. Thanks for looking and enjoy the view.
An amazing feat....and I thought you were in your tent sleeping!
As well as looking fantastic it is so helpful for people like me as a map of the sky showing all the major objects and their spacing from each other.
Great for planning an imaging session of the Milky Way.

Thanks mate. No I was watching Jaws 3 on telly. Too cold outside

Thanks Greg. Funny enough I didn't really align it. Must have been one of those freak alignment where you're spot out of the box. I did a 7min test sub the first night though with minimal trailing to test.
Marc, plate solving probably won't work. When the software stitches the frames it has to straighten the lens distortion and that throws out all the object relationships that plate solving requires. It's not as bad with long focal length lenses as with it is with short ones but still not wonderful. You could solve each frame and try to mosaic the results.
That's awesome! Even Corona Australis nebulosity is clearly visible.
Thanks a lot Troy. Yeah it is too.

Thanks for the feedback Steve.

Thanks Andrew. You're right. UNIMAP seems to lose it. I'll try your suggestion.
Lovely mosaic Marc, you stitched the different panels remarkably well (not an easy task, in particular on large fields) and the whole image is a pleasure to look at full resolution

Thanks Marco. I have to admit I am a little lost with DSLR processing still. There's a lot more corner aberrations and a fair bit of overlap is needed. Haven't quite figured out the stacking either as they're not FITs. A bit out of my comfort zone.

Thanks Andrew. Maybe the starfield is too dense. I'll try to do the panels individually then register the solved plates onto the original see what come out of it. It'd be cool though because the constellations would start to appear as well.

What are you stacking with Marc? Sony's software will convert ARW to TIFF. Nebulosity will turn TIFF into FITS, and it might turn ARW into FITS.
AutoPano will stack JPEG, TIFF and some RAWs (not sure about ARW). It also handles the lens distortions. Not exactly cheap, except compared to anything from Adobe.
Another great mosaic Marc - seamlessly stitched together! ... and with a 35mm DSLR this time - you are certainly getting a broad range of experience! Apart from some distortions at the extreme mid/upper left, the stars look quite good; considering the short fl / wide angle of these lenses it is an excellent job that you've done here. I'll be interested to see the plate solve if you can get it to work.
