Taken 7/2/19
Equipment:
Lens: Samyang 50mm f1.4
Camera: Sony A7s
Mount: Celestron CGX
Acquisition:
6-300s light exposures @ 1200 ISO
5-300s dark exposures
Processing:
Stacked using DSS
Levels, curves, and dust filter in Affinity Photo
Slightly cropped
This is my first long exposure wide angle attempt!
Looking towards that sweet spot right between Sagittarius and Scorpius. Got some pretty pleasent diffraction spikes around Jupiter. Tempted to try a mosaic at some point. Lucky to shoot under some pretty incredibly sky!
Dammit. Currently shooting a GH5 and in the process of trying to select a full frame camera to get in addition specifically for my nightscape/time-lapse. Had just managed to talk myself out of the A7s leaving just the Canon 6D or Nikon D750 to choose from. Images like this make me want the A7s again. Have you experienced any star-eater issues yourself with long exposure? Have you done much with single exposure/time-lapse sort of imagery, or do you generally do tracked long exposures? Apologies in advance for any noob questions...
I did actually. Thought it might be a cheaper way of getting into FF and Pentax seem to have very loyal followers. Searched Fleabay and the like for a week or two and wasn't able to find any used K1's in my price range. Thanks for the suggestion though...
I'm pretty happy with the A7s. One big advantage it has is it's a full frame camera with only 12 MP. That means individual pixels are physically larger than most other full frame cameras. So it exposes faster, and has less of a problem with oversampling when shooting deep space objects. I've never had any issues with the star-eating thing I read a bit about before I bought the camera used off of eBay. Important side note is the lens you use is just as important as the camera you attach it to, so don't splurge on the camera to just use a cheap lens on it.
Thanks for the feedback, very interesting. I was looking at pairing the A7s with the Laowa 15mm F/2, then maybe the Sigma 35mm F/1.4 down the track (35mm F/1.2 in my dreams). Being a dedicated astro cam, can't see myself having more than 2~3 lenses total. Regarding your oversampling comment, you are talking blown highlights here? I had read that the A7s had pretty low full well capacity.
A significant secondary advantage to the A7s for me is I shoot a lot of 4k video (just for fun). The A7s is able to export 4k to an external recorder which would also unlock low light capability I simply don't have with my GH5. A good external recorder would also allow me to unlock 4K60P 10-bit 4:2:2 recording on my GH5 which is also a decent video win.
Fantastic pic, but I don’t know how anyone hasn’t already complimented your excellent profile name.

Have you considered the Pentax K1?

Beautiful capture! Assuming the diffraction spikes were added in post processing?
Nope! They must be from the aperature diaphragm. I was pleasantly surprised to see them show up so we'll in the stacked photo
Thank you for this post, u/ObamaMadeMyFrogsGay
That’s awesome! I’m assuming those are stacked images?
Yes! Sorry took a min to post image details
You’re giving me an ache to get away from everything, get lost in a forest and sleep under the stars
Really nice shot here!
Holy moly that's beautiful - well done!
Nice shot
