A99II = star eater ?

Well with the smoke in the air, not much astrophotography going to be happening, but the sunsets are amazing.

Actually it wasn't to correct the problem. If it was it was unsuccessful ;-)

It appears I had it backwards. A firmware update caused the problem. ;-)

Yes. before you could shot 30 seconds exposures without the camera eating the stars. the problem was only in Bulb. Not it's everything above and at 4 seconds.

It's nice to know there are a vast and uncounted number of stars. I don't think the Sony cameras will be able to eat them all.

If that is going to happen Sony have to outsell Canon and Nikon ;-)

Fun aside. It would be great to see some samples beside that one example at Dyxum.

Well, I am planning on being in the area of the Dominion radio observatory near Penticton BC, next week. In addition to having no cell phone coverage, it is quite dark there. I will have my A99M2, 2470Z and my tripod. So subject atmospheric conditions being favorable, I plan on trying to get the Milky Way.

Its going to be clear and st....ng hot, my only concern is smoke from all the forest fires. If i get some success, I will post my results.

Well as the Sun was going down last night, the sky was a yellow tinge to it and I said to the family, smoke in the air.

Well this morning this is the situation.



Lots of smoke in the upper air. You can't smell it this morning, but that's a lot . Nice shot of the Sun though.

Bummer. Nice Gallery you have Brett. Btw. Are you happy with your ZA 50 f/1.4 ?

David

Thank you David. You have some very nice images as well.

The 50/14CZ is probably my least used lens, for no other reason than the nature of the lens. Having said that it is a wonderful lens and wouldn't part with it. The two lenses that are on my bodies 90% of the time are either the 2470Z or 70200G.

Thank you so much Brett.

Nice to know it's a great lens. I actually had the 2470 but sold it because of missing sharpness.. So use my old Minolta 24-105 which is great stopped down. But I would like to get some primes and thats my reason for asking about the 50mm.

Hi all.

Have any of you tried if the a99II eats stars ;-)

Trying exposures shorter than 4 seconds, longer than 4 seconds and a bulb.

Best regards

David Cartagena

If it exists, its hardly noticeable...would take pointless pixel peeping to really see any notable difference from my personal experience.

Even though these are not strictly star shots like a full on Milky Way image, these stars hardly varied in the hundreds of shots that I took on that evening...

Great shots Martin.

I think it would be more noticable when the sky is darker and with less light pollution since the camera will see more faint stars.

David

Here's a recent [city] night shot [excuse the light pollution] with the A99m2 and try as you might [this is a unstacked reduced file size] find eaten stars....but I don't it would account for anything...

I think you're fine. No star eater here. All of these are a minute +

How do you know? Do you have the night sky memorized? ;-) The fact is for those us just trying to take a photo of the night sky it's not an issue. If you are doing a sky survey counting every star it would be.

I know because I took an image at 3.2 seconds which is not a star eater problem, and one at 5 seconds which is supposed to be and they looked identical. If you did this with an A7r2, it would be a huge difference. I have both.

That's good enough for me ;-) Try one at 30 sec.

So far we have reports of one yes, it eats stars, one maybe, and one no, it doesn't.

They can't all be right.

 

[pizdets17]

ones I posted are 60 seconds and more

The yes examined it very carefully and said "I can see that the bulb exposures are definitely eating some of the tiniest stars." I would imagine most people would never notice it.

 

[pizdets17]

Here it is again. One is 2.5 second which supposedly does not eat stars, and one is 6 second which supposedly does. I don't see a difference
