Wedding proposal: A customised illuminated reticle eyepiece?
« on: December 27, 2017, 07:26:34 PM »
Hi all,

I am hoping to propose to my girlfriend by writing the question in the sky through my telescope while we're out stargazing. I have seen that other people have printed solid-text messages on a regular eyepiece and then used the moon to illuminate it. I would rather not be restricted by a full moon, and would prefer to use an illuminated eyepiece, so she can be looking at something like the Orion Nebula and then turn on the message (or something like this).

So my question is whether there is somewhere or somehow I can get a custom message engraved in an illuminated eyepiece. I have seen homemade custom jobs, but I don't trust myself with this in order to save some money. I wouldn't mind spending some money on a higher-quality job and something we can keep as a reminder.

Any suggestions? I'm open to ideas for other methods if you have any too.

Thanks in advance!

Edit: I am located in Australia

PulsarAstronomer,

I do not know your location so I can't recommend anything close to you, but do a google search "glass engraving services" + your country and you will get a ton of hits.

Here's one for example in the UK, one in Australia, one in Canada and a ton of them in the USA.

Good luck and I hope you keep us all in the know about how this folds out

P.S. Here's a couple of choices re illuminated reticle eyepieces:this or this. Important to pick one where you can focus the reticle as well.

Hi Nick,

Thanks, I'm in Australia.

Good idea just going to a glass engraver separately, but what glass would I actually be engraving? As far as I understand it, the engraved glass in the illuminated eyepiece is on the inside, and would already have a crosshair or something engraved into it, yes? Can this be easily removed and replaced by another piece of glass without spoiling the optics, or would I have to just do the engraving over the crosshair on the existing piece?

Hi PulsarAstronomer,

I would expect the reticle bit to be a flat glass so it would have to be removed and replaced. Otherwise, you have a circle split in 4 quarters and you can spell something in each quarter of the circle. It's 4 magic words anyway, "Will you marry me?" and fits perfectly. BUT, I recommend you get 2 eyepieces, one for disassembly and test run and one as a backup in case something does not work out with the first one.

As an idea, make the letters really thin and sharp and not overtly big, plonk the eyepiece in the focuser and defocus the reticle completely. Then lie through your teeth that you can't get it to focus and get your girlfriend to focus it for you and sucker her in. As she is trying to focus, I hope you have the champagne and 2 glasses ready for her

I STRONGLY suggest you also get a Go Pro or something similar, put a couple of red lights to illuminate the area and film the whole thing

Good stuff, thanks for the suggestions! I definitely plan to film the thing and have some photography equipment ready too

Do you know how simple it is to remove the glass from these things? Are any brands or models easier to take apart and reassemble than others?

...And I guess if I keep the crosshair piece and just engrave over it, the eyepiece can still be useful to me for alignment!

Unfortunately I have not played with any of these eyepieces in terms of disassembling them.

However, these eyepieces are of a simple design so if you are careful and put the parts in order. With guns in the army we would always disassemble and place parts from the left to right so that we would then more rapidly assemble the gun (being right handed).

Same logic applies here. Clean environment, wash hands to remove skin oil, wear gloves, disassemble eyepiece, take notes on the way and photograph order of assembly, take part for engraving and then reassemble.

Get two of them and play with one. The cost is not prohibitive and you want to be prepared for every eventuality.

I am sure someone will chime in re disassembly and all. It's now a bit after midnight in the USA and out brethren across the pond are either observing the moon or are fast asleep!

The glass needs to be in focus so that means it needs to placed at the field stop of the eyepiece. With most Eyepieces that would be easy.

Apparently some Eyepieces with reticules do use a glass reticule, you could simply replace the reticule with your special reticule..

Would it be as well done to engrave a simpler eyepiece with a lens right at the field stop and then observe a bright object like the moon, maybe before sunset to have a fully brightened field, or sun with white light filter? The best I ever see dust, for instance, in an ep is via solar white light. Simplifies the photography too.

You could work with a Telrad and replace the reticule of the Telrad.

Hi Jon,

replacing theglass reticle sounds like the plan for now, but do you have any idea how to go about doing this? i.e. is it relatively simple to open up an illuminated eyepiece and get to the reticle?

I'd prefer to go this way than a telrad.. Even though that would be easier, it wouldn't be as romantic I think.

And to Dick, printing some solid-text on a piece of glass or lens of a regular eyepiece and using the full moon is my backup plan. I could go either way, but I like the sounds of the illumination for now. Problem with the moon is that for it to be large enough to show the message, it would spoil the rest of the night's observing.

Earth to PulsarAstronomer!

You really think you will do further observing after you propose???

Hahaha I was thinking beforehand

But I was also thinking this would be a multi-night camping trip, so I don't want adjacent nights spoiled

Yeah thanks that was actually my first idea... but there were a few problems with that: 1) my handwriting is terrible 2) it would have to be very small and a delicate job to create and 3) to be in focus it would have to be at the field stop like the reticle in an illuminated eyepiece, so I don't know if it is actually any simpler

I think that would depend on the particular eyepiece.

One thing to keep in mind: You will be looking at the reticule highly magnified so any flaws will be very obvious..

Right you are, so I will spare no expense on some fine engraving if I can actually figure out how to get to the reticle in the first place hahaha. Do you have any suggestions for eyepieces that are simple to open?
