Milky Way 15minutes and 2 hours of Ha

I did a test of various exposures last night.

This one worked out about the best.

15 minutes ISO200 (the lowest ISO on the Fuji XE1) at F4, 14mm lens.

The trees are from a 2nd short exposure untracked. There is also 2 hours of Ha added in from my Milky Way mosaic project.

Yes I used my Polarie. At first I just used the compass and tilt meter accessory to align it but there was some trailing at 10 minutes so I polar aligned. It only took something like 5 or 6 minutes. Lens was Fuji 14mm F2.8.

The Ha is from a Proline 16803 and Nikon 50mm F1.8G lens on a PME and 6 x 20 minute exposures. It took a lot to align the Ha with the colour as I had to use the transform tool in Photoshop manuallly.

That's amazing, so what does the polarie costs I've been thinking of getting one, is it easy to setup?

I think its around $450. Yes its fairly easy to setup. I just set it up just then and it took about 12 minutes to get it polar aligned and ready to go.

The polar alignment scope is really very needed for accurate alignment and best results. That costs another $150 or so.

so that's about $600 in total, plus I've already got a tripod can the polarie just mount on a normal tripod. I do own a heavy duty tripod.

Yes it does but you need a 2nd ballhead to mount onto the drive of the Polarie itself as well as a tripod head on the tripod.

That's awesome Greg, the XE1 looks like a great camera.
The extra Ha is very well done.

Thanks Mike. Originally I planned it only as a test and I have multiple exposure lengths/ISO settings as a test of ideal settings. It looked better than I expected. This is from my front yard!

Thanks Jo. yes the Fuji X series now starting with the more budget XM1 (otherwise its the same internals, in fact slightly more modern) all have superior low noise at high ISO. Its from the fact Fuji invented a different colour array that goes over the already excellent Sony Exmor 16.3mp sensor that is used in many cameras (Sony Nex 5 and 6, Pentax K, Nikon D5100 and probably several others). One of the benefits of the colour array is less luminance noise and less colour noise. Its a 6 x 6 colour grid as opposed to 4x4.

I did some comparable images last night with my D800E Nikon so it will be interesting to see how the 2 compare. The Nikon weighs about 3X as much as the XE1 which may mean the Polarie can't do real long exposures with the D800E whereas the XE1 is light so it can cope better.

Greg.

Now that is something different. The Ha certainly makes the image unique Greg. I think it might be good to tone it back just a bit though. It looks slightly monochromatic, but overall I reckon it really works as a concept. Well done.

Thanks Paul. I'll check out the tone. I was pretty happy with it considering it was taken from my front yard. Again shows how long exposure rules astrophotography.

Thanks Ian. The 14mm lens has some aberrations in the corners. I don't think the 16 zoom does. Also Samyang just released a 10mm F2 for this camera. It might be worth a look.

Greg.

I have done some more over the last few nights. I am at my dark site now so hopefully a few clear nights and I can finish a few major projects I've been working on now for over 2 weeks.
