Newton Orion Optics VX10 10PV 250mm f4.8 Newton Orion Optics VX10 10PV 250mm f4.8 optical tube

The VX series of telescopes from ORION OPTICS UK consists of a set of newton reflectors that can be parameterized to have a tailor-made equipment according to the needs of the observer.

Telescopiomania.com is aware of the gap in the market for certain types of quality newton reflectors, so we have taken the liberty of making a previous selection of those tubes that we believe have something new to offer.

The VX series is the culmination of combining many of the qualities already present in the optical tubes manufactured by ORION OPTICS UK years ago, such as the old Dobsonians, the Europa and SPX series.

With a faster focal ratio the VX telescopes are excellent for astrophotography and for visual observation of deep sky objects. With a certificate of optical quality assurance, each model is supplied with a complete ZYGO report showing the characteristics and performance of your telescope's mirror.

While it is true that the VX series telescopes are supplied by default with a HiLux optical treatment with a wavefront perturbation of 1/6 PV(Peak to valley or Pico-Valley), at Telescopiomania.com, all the VX series telescopes we offer already come with a specific enhanced treatment that makes the wavefront perturbation ONLY 1/10 PV!!!!

now that's a newton reflector that will give an impressive result!

It is worth remembering that when we talk about a PV(Peak to Valley) disturbance, we are referring to the distortion that the wavefront undergoes when passing through the optical system (especially referring to the reflection on the mirrors). Logically, the smaller this distortion is, the better, as this will result in a much sharper and more defined image, since the disturbance suffered by the wavefront will be less.

Therefore, having an optic with a wavefront of 1/10 PV is much better than having one with 1/6 PV.

The following is an indication of what is included as standard in each of the VX equipment provided by Telescopiomania.com:

1/10 PV HiLux optics
Fan-assisted tube thermal cooling
9-point suspension primary cell
Precision Crayford OC1 focuser
Quality, fully adjustable secondary spider
50mm finder
Black tube rings that can be attached to a wide range of dovetails.

VX10 1/10 PV tube specifications:

If you are looking for a large diameter, handmade, UK manufactured telescope designed for observing and photographing galaxies, nebulae, star clusters and even good contrast observation in planetaria, we recommend the 250mm diameter, F4.8 focal ratio VX10 tube.

In addition, our VX10 is supplied with a superior optic that only alters the wavefront by 1/10 PV so its optical quality is far superior to other Newton telescopes in its class.
