Some rich colours, I find it difficult to balance all these colours in wide field shots.

Thanks Justin. Mosaics can be a challenge getting things to blend in.

Thanks Rick. I have 5 panels and luminance for a 6th but the Milky Way needs to be up a bit more to continue.

Yes it looks like some colour got pushed too hard.

Its a great lens and its quite cheap. Under $300. Processing may be a tad harsh and I'll look at taming that.

Different setups seem to show it differently. Some 5D mark 11 images have the stars a nice whitish colour. Not sure what you mean about monochromatic as much of the image is the dust lanes area and there isn't a lot of colour there.

Thanks Martin. Widefield lens imaging is a nice distraction from deep sky.

Beautiful colours. Does the Pentax lens show any CA at full aperture?

As you add to this, you will have a very detailed sky map.

Thanks.

Ross.
Thanks Ross. Yes the lens shows a small amount of chromatic aberration but not very much and easily corrected. Its quite a gem of a lens for this sort of work.

Marc uses a nice 200mm Pentax and that works great for him. They are the bargain of the lens astrophotography plus they have a lot of backfocus so you can put a digital focuser in front of one.

Greg.
