You could get the same result with the F5.6 shot simply by adding more contrast/de-haze - all else equal - I believe that the atmospheric conditions / wind patterns from one shot to the next will be a larger difference vs. F-stop decisions - assuming no issues with camera shake from one shot to the next.

I am however - the worst at Moon photos!! They just don't happen for me!

I tried playing around with contrast, highlight and shadow, but just couldn't get as much sharpness out of the F5.6 shots. Admittedly I am a newbie to post processing. Yeah, conditions from shot to shot can make a difference, but there was no observable haze or clouds, so there wasn't much I could do about that other than what I did which was to take multiple shots at each setting. As for camera shake, I finally took the time this go to use a tripod and remote shutter release and there was no real wind, so it shouldn't have been an issue. The other possibility is that maybe the camera was better able to focus at the larger aperture? I'm using autofocus which I know is not ideal for this type of photography, but at only 300mm the moons image is not really large enough in the camera to focus well manually, at least for me. Definitely a work in progress...

It's all good - you can also have minor focus variation from one shot to the next... that's why I took my 90d out of panic chihuahua mode! :-D

Whatever the case is - prob best to do multiple shots utilizing diff apertures and then you bring home the keeper!

Second try at jupiter. Guessing to get the moons without overexposing the planet, you either need to stack images. Someday I'm going to get the adapters to attach the 90D to my 10" SCT.

Has anybody taken a shutter count from a 90D?

I bought mine used about a year ago from a kid who only used it for video. He told me he'd never tried just taking a picture with it. I got the impression it was bought with dad's money and he got bored with it. Used but unused.

Anyway, I took it home and took a shutter count. Dire Studio Shutter Count gave me <3,000. I thought, OK, that's in the range I was expecting, but my other cameras give me an exact count. Maybe below a certain number, that's all they can get?

It's not my main camera, but a year later, it's seen significant use. And with a long lens, it's my action camera, so burst mode gets exercised. If I had to guess, I'd say 8-10K on the shutter. Shutter Count tells me <18,000.

So all I know is that it's got somewhere between 3001 and 18000 clicks.

Is anyone else getting an exact number? Is there something about the 90D that keeps Shutter Count from getting that?

If you have a Linux box install gphoto2
Plug your camera in but do not mount it

Run gphoto2 --get-config/main/status/shu​ttercounter

This worked on my T3i and my brothers T4i. In the case of my T3i I had used his card to take test pictures for him. Unfortunately my camera inherited the picture count from his card. Still waiting to fix it.
No warranty :-)

Canon is a pain in the rear to get a shutter count from. It started with a certain processor build, Digic 4 or 5. You have to hack the OS now to get at the shutter count. I've only found one app that I can make work most of the time from a company on the brighter side of shady. And they only make the app for Apple products. It's one of the 3 apps I run on an Ipad.

I've got 3 DSLRs, all with different processors. The 90D is the newest with a 2019 Digic 8. Canon doesn't run OS changes by Dire Studio, ever. Maybe DS hasn't cracked the code for the Shutter Count product for the Digic 8 processor. And maybe they've moved on to Digic X or whatever for Shutter Count, leaving us with rough approximations.

Oh well. Has anyone else noticed approximate shutter counts on the 90D or is it just me?

I've never been able to get a shutter count from a Canon body. But I number all my pics sequentially starting at 0001, so I always know how many shots it has taken. This has proved sufficient too when selling a body, even if it is just my say-so to the buyer.
