I had to strap on the nitrogen filled tanks to go deep diving in the Amazon to find these:

 

1. Say you want a "1.25" Ultra Wide Angle Eyepiece Lens 6MM Focal Length 66-Deg Multi-Coated for Telescope (Without Lens Cover)" and you want it for $4.79 AND free returns if you don't get your $4.79 worth? And you want it with good reviews? And you want it to work as a fully functional monocular, either visually or with your phone? And you want it with a 52mm objective lens? Ok, "pugs", you've got it!:

https://www.amazon.c...5&sr=8-209&th=1

 

2. Say you want a 2x fully multicoated barlow lens that screws onto the bottom of your 1.25" eyepieces without the muss and fuss of a barlow barrel? And you want it for $ 5.99 plus free returns plus an extra 20% off coupon if you don't get your 2x's worth? Well, here it is:

https://www.amazon.c...4927749&sr=8-50

 

3. Ok big spenders, say you want a SVBONY SV113 Telescope Eyepiece HD Fully Multi Coated Wide Angle 65 Deg Telescope Accessory for 1.25 inches Astronomic Telescopes(16mm) for $15.99? 

You got it:

https://www.amazon.c...34&sr=8-41&th=1

 

Ok, time for me to surface again and recharge ny tanks!

That first one is clearly some sort of crappy monocular based on the pictures.

So, I'm wondering if it would work in an older Celestron C5 spotting scope? confused1.gif

I don't see any reason why it wouldn't but if the 16mm eyepiece didn't suffice, I see svbony on amazon says it's returnable until January 31, 2022.

Looking at the reviews:

"It is NOT a telescope eyepiece. The ad is a little mis-leading. However, it is a nice quality monocular telescope. The view is great. Optics are great. It is like looking through 12 power binoculars with one eye closed."

"I expected to get an Eyepiece for a telescope, but this is actually a self contained telescope. I was pleasantly surprised. It is a good deal for the price, and I am pleased with the value. It is lightweight plastic, but appears that it will hold up. The clarity is very good for the price point. It comes with a storage bag with belt loop, and a device that clamps your phone in place. The image quality though the phone is good."

I'll find out...

It's easy to say to "buy quality" when you can afford quality, but I think there's always room for things that are cheap and also competent.

 

Now, whether these are competent or not, who can say. They're not familiar products.

Received the monocular described in the first link today as well as the 2x barlow lens in the second link from Amazon. 

The monocular is a pleasant surprise especially at its price point. For $4.79 you get a functional optic with the following specs: "16x52", "66 meters/8000 meters", field: 22 degrees. The lenses appear uncoated and they're not advertised as such. It's easy to focus and comes with an adapter for your cell phone and and a handy carrying pouch with a belt loop. When you look thru it at terrestrial objects, you see a thin blue rim of chromatic aberration around the periphery especially in bright light. Otherise, it's easy to hand hold but the eyecup doesn't fold down as recommended in the instructions for eyeglass wearers. Although the item states 16x52 on it, the box states 12x52 and I think the latter is closer to reality with this device. I was looking for distortion/bending of the slats of a nearby house and saw none while viewing through it. I'll have to check it at night and see how it does but it works for daytime use. Eye relief isn't bad on it but eyeglass wearers may have a problem with it. Otherwise, it's a keeper! Some clever DIY could probably figure out a way of rigging it up as an inexpensive finderscope but I'll leave that to the experimenters in the crowd. The AFOV appears larger than stated but, again, I'll have to check it at night.

The 2x barlow lens is a screw-on lens that attaches to the filter threads on the bottom of your 1.25" eyepieces. It easily attached to my  high quality made in Japan Orion Ultrascopic 25mm eyepiece. It may be coated as advertised but I'm not sure about that. It doesn't appear to obstruct the FOV but I'll have to wait for better weather to see how it performs. For less than 6 bucks, I might even keep it as a lens cap for some of my better 1.25" eyepieces that I've lost lens caps for throughout the years!

I didn't purchase the 16mm eyepiece in the third link as I already have an excellent meade UWA 16mm 1.25" eyepiece. However, I would guess that it would do well in slower f-ratio scopes and not so well in fast ones.

Yes, because that C5 takes 1-1/4 inch eyepieces and accessories.

I might add that the reviews on Amazon for the monocular seem consistent with my experience with it.

Follow-up on the monocular at night for those who are dying to know: central area to about 20 degrees towards the edge in the AFOV is relatively sharp and then the object is out of focus. Managed to see one of Jupiter's moons with it and some craters on the moon thru the clouds of incoming weather. Probably could work as a finder if rings or supports could be rigged for it but it would take some doing to make it happen. Works a lot better during the day but you get what you pay for...
