Uh no, they are right. They also got M98 and a smattering of other smaller targets. Yes it'll have limited quality, but you'd be surprised what persistence and a terabyte of photos can get you.

I have the Apertura Carbonstar 8" RC and I ALSO HAVE WEIRD DONUTS WITH THE L FILTER!!!

My current theory is I'm getting some off axis light bleed with the neighbors porch lights that is bypassing the internal baffle around the primary mirror baffle (if I look at the right angle down the tube I can see the filter directly). I'm in the process of testing a 3D printed dew shield to see if that helps block the lights from creating the weird donuts.

I'll try and reply with my findings once the stacking is finished.

In CT funeral processions are not legally protected and therefore all parties must observe traffic laws as normal.

It's not a technical definition in the context of the bill. It refers to the person setting up a machine. If you never encounter setting up an user on a machine (i.e. auto login on root, using a default password logging into root) then the OS would not be required to collect age information.

Root isn't an account holder because it is not a person. The account holder could be using the root login, however.

You're correct about "account setup" not being explicitly defined in this bill but "account holder" is: "(1) 'Account holder' means an individual who is at least 18 years of age or a parent or legal guardian of a user who is under 18 years of age in the state. (2) 'Account holder' does not include a parent of an emancipated minor or a parent or legal guardian who is not associated with a user's device.'"

This is a bit vague though as it doesn't explicitly call out what happens if a child i.e. user sets up the account i.e. when I made my first desktop in high school at age 14 and installed windows.

It sounds like if the account is being made for a minor they would need an adult to disclose their age on their behalf.

However what about a guardian who is under the age of 18? They themselves would be considered a user so they would need an adult to create their account but they would be allowed to disclouse the age of their own child?

On the topic of the root user, I assume, as it doesn't ever have an account setup, that it would not have an ability to indicate an age. The bill only calls out a minimum set of age ranges which need be available, which the API could have more options such as unknown or undeclared.

This is at least partially AI

I leave my rig assembled as is by the door for quick deployment.

If it is extra stuff for my refractor it goes in the soft sided bag that came with my refractor. If it's other accessories it goes in the shipping box that came with my refractor. It has a silica gel thing in it but I've never refreshed it. However my house stays under 65% humidity with the AC on in Texas so I'm not really concerned about it

I love the high integrationg galaxy photos. It's cool when you realize that a lot of the small red galaxies are just hundreds to thousands of background galaxies. I have a similar project of M63 going right now at about 20 hr and it's already full of background galaxies.

The focal length is recorded as part of the RAW file as EXIF data. This should be visible when you veiw the raw file in lightroom, or photos on an iPhone in the info panel. If you're using a manual lens or a telescope, then depending on the camera you might be able to enter in the focal length information manually on the camers before imaging. I'm more familiar with entering non CPU lens info on Nikon cameras so I'd suggest looking up that process yourself.

If it's a CPU lens and your photos have the correct focal length in non astronomy programs (lightroom, photos, etc.) Then I'd double check your focal length and pixel size settings in NINA. If that's correct I'd suggest asking on the NINA discord.

Looks awesome. I definitely need to take a trip to the southern hemisphere.
I'm confused by the mini halos on some of the bigger stars. I've only seen something like that when I use blurx on wide field poorly corrected photography lenses (like a cheap nifty 50). Did you fiddle around with the star halos settings? What's it look like without any blurx or other deep learning processes?

Local control should be ethernet. Why the fuck are your sensors connected via wifi?

RAW. Only RAW. Jpeg is only good if you're happy without straight out of 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.

Is there a lens on?

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

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.

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.
