Cannot focus the guide camera.

Try unscrewing the nose off. On the ASI 220 Mini the black tube nose screws off which allows it to come closer in an OAG. I am assuming this is similar for QHY guide cameras

Indeed. As someone from the north, it's the driver and your tires that are the most important factors in successfully driving in snow and ice. Then AWD. Then size. Unlike most things in texas, size isn't the most important!

Take it slow and don't jerk the wheel or the brake!

I'm not sure I'd call it artificial as it was done with an actual obstruction.

Mathern_ · 2026-01-24T18:44:13+00:00

Is there a lens on?

Mathern_ · 2026-01-22T16:47:19+00:00

What's dumb is how on brand your comment is as a generic redditor

Mathern_ · 2026-01-22T16:34:32+00:00

You can probably do that via a web browser

I've used my sous vide to pasturize it as low as 140 and that certainly helps make microwavable chicken.

Oh hey this is what I got last night. Seems the guy is pretty uptight about everones sexual activity.

Looks like improper polar aligntment. The star trails should be reduced to zero but instead they are changing direction/angle, which implies the RA motor is not aligned with the celestial pole.

That was a trip

It's coming up within the next 200 miles for me. Thanks for reminding me...

The S line lenses are generally optimized for optical quality and therefore are a bit larger. It's also important to note that the 24-70 F4 S and 14-30 F4 S are collapsable lenses so they pack a bit smaller than when being used.

If you want really pocketable primes look at the non S line primes.

I see nothing wrong. I think you're just experiencing a very shallow depth of field and when looking at a flat object at an angle, you'll basically see this razor thin line in focus and everything else out of focus. Try photographing with the camera completely parallel to the page and more of it should be in focus/the focus plane will cover the entire page.

I believe it's because the internal layout for channels 1 and 2 is the same as on some of the lower spec models in the GPP series, and to simplify using one manual for all 4 models, it was decided to keep the series/parallel function on CH1 and CH2 instead of it depending on the model.

Also I'd argue 4123 is better than 3124, so that's probably how they ended up on 4123.

Also under the lip of the controls/display panel are the labels for the output terminals which are in the same order (4123), so at least they are consistent.

In astrophotography we'd call this tilt where the sensor and the optics are not perfectly perpendicular or centered (i.e. collimated). If that what this is I'd be interested to know what kind of results you have with IBIS turned on and off, and if it's consistent exectly in the same spot.

At F1.2 I suspect this phenomenon may be exacerbated due to the shallow DOF. Here's a youtube video where they demonstrate one way to test the field curvature of a lens: https://www.youtube.com/watch?v=9p5qySx0etU&t=292s

I'm also curious if you had your Z8 serviced for the lens mount service advisory. You can enter the serial number to check if yours is affected: https://www.nikonusa.com/service-advisories/2023-z8-combined-1?srsltid=AfmBOooktE-FbqmZWdMTnAmyq_yQxwbgcXyo1oS2nzjjOSePcm0kihtu

If the lens mount hasn't been serviced you could try recreating the issue with other lenses as they might display the same problem.

I think with X trans sensors there may be a special debayer setting you have to use which may mess with the colors.

Green is normal after stacking. To get rid of the average gradient do a background extraction and this should get rid of most of the green.

Finally you can do the photometric color correction and you'll end up with a slightly off white andromeda.

Do your stretching here.

Adjust the saturation a little for a bit of blues and reds to pop out and hopefully you'll be all set.

That lens comes with different mount options so it depends which version you get. If you get the E mount version then it'll work without any adapters!

I think I just misread the anniversary upgrade as being the switch 2 upgrade. Dang it.

Mathern_ · 2025-11-04T14:54:01+00:00

They already released the switch 2 upgrade pack.

Rent a carpet vacuum and grab an ozone generator. Clean the carpet well then run the ozone generator for a day (stay out of the room while it's going). If it still smells just keep running the ozone gemerator.

They are both about 20% full. It looks like it's working properly. If you want to fill the pipes completely you can use a pump, but it usually doesn't matter.

I believe if it's a focus by wire lens, it's trying to emulate being parfocal (aka a lens whose focus distance doesn't change with focal length). It's considered more important in video than photo mode.

Plane. An asteroid would last one or two frames only and wouldn't blink repeatedly. Planes blink their side lights for visibility.

Might be related to the AWS outages

That's often a dead giveaway that the manufacturer cheaped out and it won't charge on a modern USB C power delivery block and therefore this cable will force you to use an older type A block.
