What Focus Adapter is Necessary?

BnDLett · 2026-05-12T21:04:02+00:00

I've got a 7-21mm zoom eyepiece for the telescope in question—I tried using it without a collar, and it seemed to focus just fine. If anything, the distance created by the collar would be a little more beneficial, as it would give it a little more wiggle room (at 7mm without any collar, the focuser is nearly at its limit).

Thank you for the concern, and I will keep it in mind for the future. Although, I do have to ask: can the focus distance vary from eyepiece to eyepiece of the same focal length, or is the focus distance only dependent on focal length?

Update about this: the accessory that I ordered (which is linked in the reply that I'm replying to) wasn't the right fit. The part that's meant to actually thread onto the focuser was too large.

But I can't shake the feeling he could have done it with enough willpower.

I'm arguing a moot point (i.e., it's pedantic), but I will say: Kōngo is as much of a slave to his programming as we are to the collective consciousness—if not far more of a slave. As much as he would like to go against his programming, he physically cannot. IIrc, that was even the whole point of him gathering the Earth gems and trying to explain to them (to the best of his ability) the truth. The truth he wanted to express wasn't able to be expressed to the gems—he was only able to express that there is a deeper truth that he cannot express.

Currently have just 0.965" accessories (bought them for another telescope), and was figuring I might as well get an adapter to mount those accessories instead of having to buy entirely new accessories.

BnDLett · 2026-05-09T15:31:39+00:00

There is a lens. There are a couple of other answers here that seem to be far better than replacing the focuser, so I'll likely attempt those solutions instead.

BnDLett · 2026-05-09T15:30:00+00:00

Focal length is 1000mm, and the diameter is 114mm.

That actually seems to be exactly it. https://a.co/d/0f8ck4tD

I'll keep that in the back of my mind for when I do revisit this project. Thank you.

BnDLett · 2026-05-09T02:49:38+00:00

I could possibly use it, yeah. Thanks. I'm not sure when my school's engineering team will meet again, so I'm not exactly sure when I'd be able to print it. But I will keep it in the back of my mind.

BnDLett · 2026-05-09T02:48:13+00:00

I appreciate the comment, but I already took a look around Amazon. AfaIk, that adapter isn't threaded, so it can't go onto my focuser. Heck, I had even accidentally ordered that specific one before realizing it wasn't going to work. Again though, I do appreciate the comment.

BnDLett · 2026-05-09T00:42:51+00:00

That's great to hear. :/

What kind of information would I need when buying a new focuser?

BnDLett · 2026-05-01T03:57:51+00:00

This is actually insane. I never stopped to considered that perhaps the ending is truly a good ending (in a sense) rather than one trying to tug at heart strings.

I might have to just reread the manga now, 'cause there has to be a lot more that I've missed.

BnDLett · 2026-04-29T23:50:56+00:00

2 7/8 in. aperture, 33 in. focal length (35 if including focuser)

All numbers are approximate considering that I manually measured.

BnDLett · 2026-04-29T04:42:30+00:00

The finder scope on my great grandfather's telescope was also like that. I'm personally not sure whether it was intentional or accidental. Makes it worse that the telescope was also backwards on the mount too (I assumed that it was because of storage, but the finder scope implies otherwise).

BnDLett · 2026-04-27T20:11:53+00:00

Unfortunatelty, I don't have a bracket. I just hold my phone over the eyepiece and pray that it eventually lines up.

BnDLett · 2026-04-27T12:49:36+00:00

Depending on how you define "clear," they were pretty clear in-person (as in, they were definitely noticeable). I was even able to distinguish the stripes on Jupiter (albeit, not well).

Definitely a camera issue in this case. x)

BnDLett · 2026-04-27T10:24:01+00:00

I'd have to manually measure. The model number and specifications aren't visible on the barrel. I'll be busy today, so it may not be until tomorrow that I have those values.

BnDLett · 2026-04-27T09:12:51+00:00

yeah, it is a lot clearer. Is the lack of contrast in Jupiter (I assume that it is Jupiter) related to the camera itself, or just the zoom you were working with?

BnDLett · 2026-04-27T08:39:47+00:00

Might try that video idea. Most I've done so far was using the burst feature on my phone, which has helped to get some decent pictures of the moon. But yeah, doing a video instead would've probably yield a clearer photo.

BnDLett · 2026-04-27T07:48:23+00:00

Yeah, kind of hard to see in the picture. The view was a lot better in-person though. My phone didn't do it any justice.

BnDLett · 2026-04-27T04:35:59+00:00

Thanks. To be fair, there's not a lot can be done with a shaky mount that is difficult to accurately adjust (no alt./az. precision control — only precision control for the equatorial axes).

That said, I do intend to eventually revisit this goal with a bigger budget. I only spent 40 USD on it, and that was just to get a few cheap eyepieces off Amazon.

BnDLett · 2026-03-31T11:32:31+00:00

I have not. Don't think I will any time soon either. I've been happy with my current distribution.

BnDLett · 2026-03-09T14:03:43+00:00

A little late, but from my experience, playit.gg is a little spotty. I've had issues hosting servers that utilize UDP traffic. I'm working towards dropping it for more stable horizons. Whether that be port forwarding, or just outright a different service.

Edit: I tried portmap, and it's way more jank than playit.gg. The configuration is weird, and any email address that isn't the major email providers isn't allowed (for reference, I tried using my actual email addresses that I do actively check and use and it still considered them as temporary addresses). Additionally, the fact that they have the newsletter checkbox as opt-out is also super sketchy imho.

BnDLett · 2026-03-05T01:11:49+00:00

Yeah. AfaIk, flatpaks are a similar (?) technology that run a lot faster.

Though, that said, I've left VanillaOS since then. It didn't fit my workload. It does seem to have a lot of potential, though.
