VX10L Lunar Images

Lunar imaging is an art in its own right! Robert Stuart has sent us a couple of great images using his VX10L. Robert offers us the Stadius craterlet system with Copernicus and the Apollo 15 landing site (see red dot) next to the Hadley Rille. Robert selected only a relative few images from a session with gusting conditions to produce these great images. Enjoy!

UPDATE: Robert has sent 2 more interesting images:
Triesnecker-Hyginus rille system and an impressive detailed montage - click on the image for a link

Stunning Lunar Images

Quite a while back, we made 3 sets of very precise optics. Mike Brown in York, U.K. is the owner of one of the sets and still uses the optics. Mike sent us these stunning Lunar images and a Star Test of the optics. If you are interested in similar optics or need something special for a project - get in touch with John.

Mike O'Day makes light work of Large Magellanic Cloud

CT12 owner Mike O'Day located in the Blue Mountains, Australia sent us us this fantastic image showing multiple bright nebula and star clusters in an area adjacent to the The Tarantula Nebula ( NGC 2070 ) in the nearby irregular galaxy, the Large Magellanic Cloud ( LMC ). The largest of these are the bright pink nebula in the mid-right part of the image ( NGC 2014 ) and the blue nebula in the lower middle ( NGC 2030 ). Mike used an unmodified Nikon D5300 on his OOUK CT12 f4 to capture this impressive image, proving that DSLR cameras have a great part to play in astrophotography - well done Mike - wishing you dark skies and many more successful imaging sessions!

Mirror Set for Ultrascope

Orion Optics UK are pleased to be able to provide optics for the Open Space Agency's "Project Ultrascope" - The Ultrascope is a robotic telescope - or ARO - Automated Robotic Observatory, that will allow amateur astronomers to construct a do it yourself, 3.5 Inch mirror ARO that is able to conduct celestial photography and photometry. The construction uses 3D printed parts, the 3D files and instructions for the Ultrascope are available under an open license.

This type of project would have been almost impossible just 24 months ago. However the emergence of low-cost 3D printers and Laser-cutting, paired with microcontroller platforms such as Arduino and Lumia 1020 - with its 41 Megapixel CCD - mean that a project such as this is now eminently possible.

Find the optics required by clicking on the logo image and Click HERE to go to the project page.

CG4 in Puppis

Posted 9/03/2015

Looking like a giant cosmic hand, or a giant space slug, reaching out to grab a poor defenseless distant edge-on galaxy (ESO 257-19) CG4 in Puppis is a dramatic example of a dusty cometary globule.
Don't be too alarmed, ESO 257-19 is in fact more than 100 million light years further away than CG4. This is another stunning image from Mike Sidonio down under in Australia taken with his OOUK AG12. Mike currently uses a Starlightxpress SXVF-H694, SX USB CFW, SX OAG unit + Atlas Focuser. Image details: LRGB = 480 60 60 60min = 11hrs total exposure (bin 1X1) Astronomik filters -20C chip temp, flats used but no dark frames used. Guide Camera: Starlightxpress Lodestar. Thanks for sharing Mike!

AG Telescopes - a Thankyou & Special Offers

Because of the popularity of our AG Astrographs over the last few years, we have decided to try and appeal to a wider audience and make all the AG’s available for a limited period at a special offer price.
The AG’s were developed with the help of several very experienced amateurs and semi-professionals to the level they are currently at. The images on our Gallery pages are witness to the performance optically and mechanically of these instruments.
These telescopes are not inexpensive and, to allow a wider audience to be able to own one, we are, for as yet an unspecified period, offering them at a special price.
We will shortly be changing our web site to show these special offers and hope we can make our AG telescopes more widely available to people with a slightly smaller budget.
Contact us in the meantime if you require further information.
John and Barry

ODK Halos and Ghosting

Frequently we are asked to look at customers images, some of which show ghosting or halos around stars. Their query is that they think the telescope's lens corrector system is creating these abnormalities. so, we asked Harrie Rutten, one of the World's leading designers of optical systems to take a look at an ODK optical design. One point to consider here is that all the ODK series of 'scopes utilise exactly the same corrector system, they are all based on same primary/secondary speeds and result in an f6.8 focal ratio. so what ever relates to one, relates to all.

Here is Harrie's email which arrived today and analyses in great detail the ghosting in an ODK telescope:....

Hi Barry.
I did full ghost analyses of the ODK 16.
I have to give you very BIG compliments.
This is one of the best ghost free designs I have seen ever. I calculated hundreds! Incredible good.
The brightness of the ghost is more than 20 magnitudes fainter as the source! This is professional quality!
If you have any questions about the analyes, please ask!
Attached the report.
Very Best Regards and many congratulations with this beautiful design which you reached without ghosting analyses . . . . incredible!


If anyone wishes to see all the number crunching and results from his analysis, please email and we will send them out to you. There just isn't room here for all the PDF files

It's all about the detail!

This new image from AG12 owner Peter Shah shows great detail in IC5146 - The Cocoon Nebula in Cygnus. Always up for a challenge, Pete captures the intriguing background emission to great effect. With a total image time of some 22 hours the AG12 certainly delivers the goods!

Power Loss

Update 17/6/2014

Power restored, about 10 hours production lost. Everything now running except coating machine which stopped with a valve open and destroyed £1200 worth of high vacuum oil. 1 in a 1000 chance the power was lost mid valve changeover on machine.

Posted 09:25 16/6/2014

An 11,000 volt cable outside our factory has exploded and we have lost power on 2 of the factory's 3 electrical phases. Luckily most of our single phase equipment is unaffected including phone lines and email. We will keep you posted








Lightweight mirror development

Posted 10/6/2014

We have been carrying out some important research development with a a large international company. one aspect of that research has been the design and manufacture of super lightweight mirrors. We are in the process of continuing that research and hope soon to be able to offer telescope mirrors which are up to 65% lighter than typical mirrors.

Welcome to our new website & Thanks!

Posted 22/2/14

Our completely new website was uploaded just prior to Astrofest this February. The response has been incredible being presented to us by the monitoring statistics. In the period from Astrofest to today, the 22nd February, we are having 104% extra page hits, 32% increase in total visitors and an increase of 27% returning visitors. These figures coupled with our best Astrofest sales ever, 11% up on previous best year and, yearly sales to-date up 16% on previous best year's start ever.
Obviously the web site traffic increase is a direct result of the web site improvement but sales increases in general can only be put down to what we believe is a general upturn in businesses in general both here in the UK and most EU countries.
We would like to thank everybody who has visited our web site and hope you continue to visit us and, thanks also to both new and existing customers for your increased support.
John and Barry

Posted 7/2/14

Any make! - any age!

Over time, like any instrument - your telescope will benefit from a General Service.
We would like to give you the opportunity to help you look after your telescope, regardless of it's make or age and keep it in tip-top condition. There are many telescopes on the market but all will perform much better with regular service and maintenance.

We are offering INTRODUCTORY PRICES on a set of 10 service procedures to your telescope to ensure you are getting the best possible performance from it and have our Optical and mechanical experts check these aspects which can cause basic problems, especially coatings which are fundamental to the telescope's overall performance.
