Looks like the image you got from the A7R has much more color than the ones from the A7Rii.  Different WB perhaps? I worked a bit w/ MW images from a friends A7Rii & found it was very hard to get ...

Yes, that helps.  Mine had lots of looseness in the altitude adjustment axle & screw on the wedge.  Movement there would easily cause small loss of PA when i changed the camera position. When I ...

You're results show your approach worked. You have no close foreground so much less demanding that the camera/lens rotate around the nodal point. Yes, the iOptron is pretty loose.  I sold mine for ...

I see no reason to think NR is being applied to either in RAW. There's no loss of detail to indicate NR. I do think the X-T10 has a lower S/N than the X-T2 due to lower QE. But the X-Trans III ...

Thanks for doing this.  Your results align with what I find from my Fuji X.  We expect new sensors to have less noise.  The pattern noise you are measuring is qualitatively similar to what I've ...

In this thread 4 mo ago I'm seeing a modest positive difference for general & starry night landscape photography from the X-T2. RawTherapee does a pretty good job of removing impulse noise from ...

I've partially followed this long thread.  I found Roger Clark's comparison of imaging results from Fuji X-T2 & one of his Cannon's his usual solid analytical work.  My experience w/ my X-T2 ...

Is this moon light or a time composite w/ sun rise on the foreground?

I believe its Star Gazers Lounge where you'll find a lengthy discussion about the problems of fixed pattern thermal noise from the D7200. But always remember when considering photo equipment, buy ...

I to am backpacking even at 72. After getting m43 several years ago, I'm abandoning it for Fuji. m43 has way too much noise for starry landscapes especially the dark landscape parts that need 2-4 ...

Thanks much.

Thanks, Filters are moved during totality.

I went back to the over 100 images I captured last August to try and create a better image of the solar corona at totality.  There are 4 published post processing methods for doing this & I became ...

With this, I'll be wrapping up my report. I need a break for corona images so I can go obsess on other images like the 8000 I brought back from Africa-:) Until you've tried these, most of what I ...

Because I've seen no successes for a full range of exposures using HDR software, I'm not pursuing that.  Here's an example of what I found.  Photomatix has this on its resource page.  And its ...

Good question. From my experience w/ my images, its possible to blow out the proms both during creation of a composite image and during sharpening/spatial filtering steps. I'll post some examples ...

Wow, thanks.  Glad you like these. Not sure these are the best but certainly different from all but a couple images out there. Yes, I've done an extensive image search and find few images that ...

Sorry, this is long. Here are the details of the exposure blending I used in PSCC. My long exposure images (1/15" through 4", f5, iso200) all had blocked up areas w/o detail. Smoke & lens flare ...

No problem with your questions.  From my experience w/ OEM profiles, they either incompletely or badly correct lens distortion & vignetting.  Since your on LR consider downloading their profile ...

Photozone has this to say about that lens: "The Nikkor shows moderate barrel distortion at 70mm switching to quite pronounced pincushion distortion at 135mm and 200mm, which is reduced to a ...
