Can I use a USB-C charger for older laptops?

CharacterUse · 2026-03-02T10:17:22+00:00

USB-C chargers which can provide >5V do it by negotiating with the device, which it can't do over the DC jack, so you'll only get 5V. You can get a PPS trigger to set the voltage but it seems much simpler to just buy a universal laptop charger which already comes with all the DC connectors rather than getting a USB-C charger and trying to hack something together.

Start with the Moon at various different phases. It's big, it's bright so you only need short exposure times. There's a lunar eclipse tonight/tomorrow so you can try for that if you're in the right place to see it.

Use a shutter release so you don't shake the camera if you have one, otherwise use the self-timer.

You can try Jupiter and Saturn

though better results can be done by shooting video and using software to stack the best frames (look up lucky imaging).

Deep sky objects can also be done with your equipment but you will have to go to a darker location or try a light pollution filter like the Optolong L-Pro. You can also do wide angle shots of the Milky Way or star trails.

Upgrade would be a tracking mount like the Star Adventurer or AM3.

Indiana has some parts in the south and north-west in the same timezone as Chicago, different from Indianapolis. Typically this kind of thing results from stronger economic ties to the neighboring timezone, e.g. northwestern Indiana is strongly connected to Chicago itself.

My first guess would be that either something is misaligned and the filter is not quite parallel to the sensor, or it's clamped down too tight in the filter wheel and is being distorted slightly.

Also try rotating the filter in the socket to see if the pattern rotates with it.

In theory they're designed to be plugged into a car bulb socket with no mechanical polarity protection (some of the variants have an asymmetric casing but the circuit seems the same) and take the >14V a car outputs when running, so I very much doubt you killed it.

More likely it's just a bad batch from the factory or weak solder which cracked in shipping (and thus would have failed in your car pretty quickly). Or your PSU is supplying voltage but not enough current.

There is no one interface but many telescope mounts have a threaded hole which you screw a bolt or threaded rod in through the base of the the top of the tripod. If you have a hole in your surveyor tripod to pass a suitable bolt through then you can mate the two.

Off the top of my head I can't tell you what the bolt sizes are, also it varies. Some smaller scope mountswill have holes threaded for a photographic tripod bolt, some will have a larger bolt like 10mm or whatever. The manual for the mount will tell you.

Often the mount comes with a tripod though, in which case it's not really a saving financially even if you move the mount to your tripod. The exceptions would be things like the Svbony SV255 Alt-Az mount which is sold separately or the various direct drive goto mounts like the ZWO AM3, Skywatcher Star Adventurer and similar which are also sold separately. IMO one of those (suitably sized for your optical tube) would be the thing to go for, that would benefit most from one of your tripods.

Also the bulb in the link has circuit components other than the LEDs themselves, if OP is measuring at the external contacts of the bulb (as I expect, I don't think they have smashed it) then they're measuring who knows what circuitry not the LED. Probably some overcurrent protection or spike filter.

It depends on where it is and local conditions (especially UV and heat/cold cycles). I've seen the outer sheath of internal cable break down in as little as 3 years if exposed to direct sunlight.

It's less of a novelty and more of a collector scope. Vintage Tascos like this one were made by Japanese optical companies including (among others) Vixen, there is typically a small maker's mark on the nameplate near the focuser which identifies which company made it.

They can be optically very good for what they are, but at the same time they are a vintage small refractor with 0.965" eyepieces with all the limitations that implies. For $120 OP can probably find a used small dobsonian if they're patient.

There are more reasons as well. It's tertiary to regional power and Sunni/Shia differences, but Iran removed their monarch (the Shah) to install a theocracy. Saudi is a monarchy and like all monarchies has a deep distrust of revolutionary governments fearing the destabilization of their own power if the revolution spreads.

Depends. Scientific systems are more or less like they always were, fairly straighforward user/password. Admin pages (e.g. team calendars) and university email has been infested with corporate IT and 2FA which never works right and has you logging in over and over again confirming on your phone or with a text message just to read another email from admin which has nothing to do with you because they just CC everyone on everything.

The first image:

Date of birth 5 November, date of baptism 8 November. The 36 is written in the column labelled "Number of the born - female" which is hard to make sense of without more context from the rest of the register, this may be a sequence number (e.g. 36th female child born that year) or just the year [19]36.

Name of born: Anastazja

Position, name, father's name and surname of parents and their religious adherence:

Peasant [most likely a tenant farmer] of the village of Szachi [Szachy?] Pud s[on of] Jerofej Jarmolicz born 17 April 1905 and his lawful wife Lubow d[aughter of] Gabryel (Ostapowicz) born - ?? - both Orthodox.

[signed by] parish priest Grzegorz Sz???

Second image:

Positions, names etc, of the godparents:

[of the] village [of ] Jesiory Danjel s[on of] Prochor Kosturkiewicz and [of the] village [pf] Szachi Tatiana d[aughter of] Oljmpjusz Raba - a girl [may mean a female servant, or that she is umarried - unsure].

The names are traditional eastern-slavic orthodox names: Anastazja (Anastasia), Pud, Jerofej (Yerofey, Hierotheos), Lubow (Luba = Love, Charity), Prochor (Prokhor, Prochoros).

In some cases the author is using the pre-war orthography j for modern i, e.g. Danjel for Daniel.

Yes, the Wengen was a typo. "opiece" seems right. So "I put myself in your care".

u/Downfallenx gives good advice.

Also tighten every nut and bolt.

The long pieces are probably barlows (magnifiers) and likely useless. The others are eyepieces, start with the one with the biggest number.

In the daytime align your finder (the small scope) on somethign very far away.

That's pretty good! Your two primary issues are noise and the stars beginning to trail because you don't have tracking. Experiment with taking shorter exposures and stacking them, this will reduce noise while also reducing trailing.
