So, taking all this into consideration, I doubt that the Svbony 3-8 Zoom would be practical in any telescope with a binoviewer. Maybe the Svbony 3-8 Zoom binoviewed might be useful in a truss-type Dob that has had its struts shortened to accommodate binoviewers without a Barlow. Or in...
To my eye, the Leica Zoom, the two TV Nagler Zooms and the Svbony 3-8 have virtually perfect parfocality. IIRC, there is another Svbony zoom that has high parfocality. Many zooms have terrible parfocality, for instance the Baader Zooms. I will never use the BZ's again unless they'r...
Constant field of view: During the zoom process from 3mm to 8mm, the field of view of the eyepiece remains constant at 56 degrees, providing users with a completely different experience of using a zoom eyepiece Parfocal design: No need to refocus no matter how the focal length is changed ...
Briefly, the SV 3-8mm that I had pre-mounted in my astrosystems low profile adapter easily comes to focus with the paracorr but as I later discovered, the zoom mechanism is below while in the adapter so I wasn't able to check the zoom functions but it did function well at 8mm while ...
Page 3 of 3 - Current Aliexpress Svbony Sales - posted in Eyepieces: I guess it depends on what size Barlow it is. My 2001 Ultima Barlow is the shorty version so the height with my zoom in it is still relatively low. I have an orion shorty... its jus
I just came back in after observing the Sun with my white light rig which, incidentally, uses zoom from SvBONY so I am very intrigued when I hear that they are about to introduce something new. Having their 3-8mm and the APM 7.7-15.4 in the arsenal already, I really hope they come ...
I am 100% happy with mine I got while it was at the "introductory" price (pre order) and bundle. And with yours being a "later" one confirms the consistency of the production run(s). For visual folks, the SV215 3-8mm Zoom is a perfect match for higher power viewing. I also purc...
I am 100% happy with my SV550 122mm Triplet with very little to no CA visually. Venus was color-free lower on the horizon if that tells you anything. I was using the SVBONY 3-8mm zoom eyepiece. The CA will always vary depending on the eyepiece(s) where some actually introduce "color...
A SVBONY SV215 Zoom Eyepiece was included. I am wondering as to opinions on how ths 3mm - 8mm will perform in this scope? Edited by Skooter1121, 24 January 2024 - 03:20 PM. Terra Nova, StevenBellavia, Oldfracguy and1 otherlike this ...
of its settings and I was quite impressed with the image, particularly at the 3mm range although Ernest pegs it at 3.5mm but I'm using a paracorr so that drops it back below that level. The more I use the Svbony 3-8mm zoom, the more impressed I am with it. I find both of these...
