Svbony SV154 2" 26mm SWA 70° Super Wide Angle Telescope Eyepiece

For the price, this is a great eyepiece It's a bit snug in my 8"Dob, and I have to pull it out a bit to get good focus. All in all, I get great views with this eyepiece. It stays in my telescope most of the time now.

Good for price I compare this to my Saxon 21mm SWA (68 deg). The Saxon definitely has less coma than the Svbony (seen through my f5 dob)! That is pretty much the only complaint I have about the glass in this eyepiece, otherwise the centre of the image is clear and sharp. The outer build quality isn't that high comparable to the Saxon but that doesn't really matter (things like rubbers slightly overhang). Eye relief is fantastic and is great for the price you pay. I am pretty sure that the SV154 is just a carbon copy of the GSO SWA but sadly cannot compare. No regret buying this eyepiece for the price can nearly get the entire of subaru/pleiades into the eyepiece.

Better than expected. To test it out, I set the eyepiece up on an 11" SCT with a Baader solar filter and shot a picture of a group of sunspots with a cell phone on a bracket mount. The image came out better than expected.

Great Budget 2” Eyepiece!Great Budget 2” Eyepiece! To start, I would say this eyepiece blew me away. I’m in college and doing astronomy on a tight budge. This eyepiece came exactly as advertised! I own a 12.5” f/5 dobsonian telescope and the views were fantastic. The eyepiece gave a full 70 degree field of view and through my telescope it provided me 1.14 degree true field of view. This allowed me to see large objects like the complete double cluster, M81 and M82, M108 and the owl nebula, and most of Andromeda. It also split the double stars of Mizar and Albireo very nicely. Globular cluster were especially good and I could see individual stars in most of the brighter Messier ones. I could also see the distinct dark lines in M13. Granted I have a telescope with a large aperture which really helps, so keep that in mind. The moon was also amazing! I could get then entire full moon in the eyepiece. Now the down sides to this eyepiece. The edges of the field of view were not as sharp as the center.. You can kinda see that in the picture of the double cluster I added. However, It wasn’t horrible but definitely noticeable. It’s also quite heavy and I had to readjust my telescope’s balance. If you can live with those, this eyepiece is a steal. Overall, this eyepiece is of high quality and my go-to out in the field. Recommending this to anyone on budget looking for amazing and affordable views.

SVBONY SV152 20mm SWA 70° Illuminated Crosshair Eyepiece 1.25 inch

Reticule visibility remarks when finding any issue.Reticule visibility remarks when finding any issue. Hello! For those that have had issues with the reticule, please observe the following tips: 1. Use the two batteries supplied; with only one battery the LED lights, but the intensity is not enough to guarantee visibility of the reticules. Observe also the polarity while inserting the batteries into the eyepiece hole: they must be with the positive (larger metallic case, facing out or up); both batteries in the same position (in series). 3. Make sure the batteries faces are clean on both sides. 4. Measure the batteries for correct voltage, before using them. With a multimeter in DC range, measure that both have 1.5Vdc or more. Batteries might be received discharged (seller’s responsibility). 5. Before using the whole eyepiece, I checked the ocular was correctly focused to the reticule: I let a little light (natural or artificial) enter by the hole, where the illuminator is supposed to be screwed and tuned the focus by rotating the ring of ocular, until you find the reticule is clear and focused. 6. The internal bottom contact of battery compartment, is not a very good quality one, so, I cleaned it a bit with the tip of a little screw driver flat type, and gently guaranteed it was shining. 7. I also stretched a bit the spring that touches the positive of battery, to guarantee good contact and pushing strength to both batts. 8. Before the illuminator is screwed into the matching hole, it must be tested first alone. Test it by verifying that the ON/OFF switch and intensity control are functioning OK, this is evaluated by looking into the LED while rotating the upper knob of it. Hope this helps! Cheers!

Check your contacts! The eyepiece itself is of good optical quality. However the illuminator didn't work, even though the batteries tested good. Looking closely, the negative contact is a literal blob of solder. Scraping the surface of it either cleared away some oxidation, or a moisture proof coating that was preventing good conductivity, and the illuminator worked perfectly after that.

Ottimo prodotto ma arrivato senza le 2 viti M4 per blocco oculare L'anello adattatore funziona ottimamente ma le 2 viti M4 che bloccano l'oculare, visibili nella foto del prodotto, non ci sono. Si possono avere?

SVBONY SV149 Canon DSLR Lens to 1.25" Eyepiece/Astro Camera Adapter

Locking mechanism - slide it, don't push Got this to mount a ASI 120MM-S astro camera on a Canon EF 75-300mm kit lens. The adapter is a combination of three elements; the last is a M42 female to 1.25" nozzle adapter. I could only get the right backfocus when I took of this last nozzle adapter and screwed on the ASI 120MM-S (which has M42 female thread) on the adapter when I removed this M42-1.25" nozzle adapter. The lock mechanism kicks in when mounted on the EF lens. Turned out the little nob is a not a push button, but a slider : you have to push it towards the camera/eye piece for it to release the EOS EF interface. Works well and is generally of kind of good quality. Certainly need some extra support when doing precise imaging.

SV139 Telescope Filter 1.25inch ND Neutral Density For Moon Viewing

These are a must have! When the Moon is full or nearly so, observing even with 10x50 binoculars can "sting" my eyes! So "Moon" filters are a must have item. I use 13% transmission filter just observing a near full moon with my 6 inch telescope!

SV139 Telescope Filter 1.25inch ND Neutral Density For Moon Viewing

Great filtering, doesn't fit my 1.25 inch lenses The ND properties of this filter are nice especially for the cost. Glass has good clarity. I like that it's gray rather than the typical green or even blue. Good finish, but unfortunately doesn't fit most of my standard 1.25 inch eyepieces so I'm docking a star. Not a big deal for me because I'm ordering more SVBony lenses so hopefully those work better together. But as is, a little disappointed. Easy enough to tape, but you shouldn't have to do that. Not exactly sure what the problem is here, maybe a disconnect between metric and imperial but as I stated earlier these should be a very standard fit.

SV139 Telescope Filter 1.25inch ND Neutral Density For Moon Viewing

Too dark for a moon filter but should be OK for use with a Herschel Wedge solar viewer. This filter is very dark, too much so for a moon filter but it is the correct rated density, ND3, for use with a Herschel Wedge, combined with a linear polarizer, for solar viewing. Both filters MUST be mounted on the eyepiece or in the eyepiece holder of the wedge AFTER the wedge prism in the Herschel wedge. Improper use for solar viewing IS DANGEROUS. Baader and others have downloadable Herschel Wedge instructions. Do a web search for Baader, Lunt or other Herschel Wedge Use Instructions. The Svbony filter is only single side male threaded with no female threading so if used in a stack it must be the outermost filter.

SVBONY SV137 1.25" 2X FMC Barlow Lens with Brass Ring for Telescope

Brauchbare Barlowlinse für den EinstiegBrauchbare Barlowlinse für den Einstieg Ich habe bereits die 2x in Einsatz und diese als Ersatz für meine 3x Plastiklinse gekauft. Die Verarbeitung und Qualität wirkt wertig. Bis auf die Linsen und der Gummiring ist alles aus Alu gefertigt und ist sauber gearbeitet. Auch die Feingewinde sind fehlerfrei und die Alu-Teile sauber eloxiert. Die Linsen-Qualität geht bei dem Preis in Ordnung. Details auf der Mondoberfläche werden sauber dargestellt. Es gibt aber einen Punkt Abzug da der obere, innere Teil leider nicht geschärzt ist. Bei einem langen Okular ist dies kein Problem, bei Kurzen können aber schon Lichtreflexe entstehen. Wünschenswert gewesen wäre auch eine einfach Aufbewahrungsbox. Gerade in Fernost wäre dies ein Cent-Artikel. Leider ist die Barlowlinse nur in einem Polybeutel in einem kleinen Karton verpackt. Ansonsten gerade für den Anfang eine preisgünstige Einstiegslösung im Vergleich zu irgendwelchen Plastikteilen.
