New professional printing service in use, the One Vision Imaging UK
I have updated my image portfolio account, Astro Anarchy Zenfolio, with new professional printing service, please have a look
(Images can be ordered only from the first two folders!)

The larges print made out of this Moon image was 5 by 5 meters.

The Service
There is now a new, very high quality, professional printing service added, the One Vision Imaging in UK.
They have more medias and sizes available, including metallic photographic papers. The maximum size is now 101,5 x 152,5 cm. (Large images can be ordered by contacting me directly, astroanarchy@gmail.com )
One Vision Imaging is one of the largest professional photographic laboratories in the UK. For well over 30 years One Vision Imaging have been servicing professional photographers with the very highest standards of processing and finishing.
- Each and every file is colour graded, density and contrast controlled.
- Extensive colour stability and life expectancy on all offered papers.
- Vast range of print options including standard square and panoramic sizes.
- Choice of Lustre, Gloss or Metallic paper finishes.
Available Photo Papers
One Vision Imaging uses Fujicolor Professional TYPE DP paper. The base support and silver halide crystal control technology work together to produce improved whiteness, highlight and shadow depth qualities, making this an all purpose colour print paper for the photofinisher.
You have a choice of Lustre, Gloss or Metallic paper finishes.
Metallic prints give a distinctive look to most colour shots, black & white and sepia images are particularly effective. With its glossy finish and metallic appearance, it represents another dimension for creating images with exceptional interest and depth. Metallic paper adds stunning visual impact and a contemporary flair to your photography.
Price level
Price level is between 21.95€ (20x20cm) up to 853.95€ (101,5x152,5cm) with Glossy or Luster finishing on Fujicolor Professional Type DP paper.To guarantee a top quality photographic printing, ICC-color profiling is used with all images. Metallic paper is little more expencive, all prices and sizes can be seen at Right hand side in my portfolio, when image is clicked large.
My image portfolio, please have a look
You can place your order trough the web-shop in the portfolio, or by leaving an email to me directly.

An other collection of images, Meade LX200 GPS 12"
My main instrument is an old Meade LX200 GPS 12" telescope. With lots of tweaking, it works as an imaging platform. An original fork mount has a largish periodic error but I'm using the Starlight Express active optics unit, LXV-AO, with it . With an AO-unit, the tracking error is more or less zero. Since I'm using the QHY9, with kind of small diameter CCD-shell, as my imaging camera I have reduced the original f10 scope down to f5 it gives me an effective resolution of about 0.8 arc seconds/pixel. It's done by "misusing" the Celestron f6.3 reducer by adding some extra distance to recommended 110mm. There is some light coma at the corners but I can live with it for now.

(What a mess...)
I'm using two camera lenses, with the Meade, the Tokina AT-X 300mm f2.8 can be seen in the image above. Canon EF 200mm f1.8 is my second camera lens for the astrowork.
Image collections with both lenses can be seen in HERE.

A collection of images, Canon EF 200mm f1.8 optics
I have couple of high quality camera lenses for astronomical imaging, Tokina AT-X 300mm f2.8 and Canon EF 200mm f1.8. Both lenses are wonderful instruments for an astronomical work, I always use them both full open.
Focusing under a fast f-number is very difficult task due to extremely narrow critical focus zone (At f1.8 the critical focus zone is around 7 microns, 7/1000mm) I have build an automatic focusing system for all camera lenses, images of it can be seen HERE and HERE. The system also compensates the temperature drift.
An other challenge is orthogonality between CCD-shell and optics. With slower optics this is not much a problem but with extremely fast optics a micron scale accuracy is needed. I have done hundreds of iterations with the CCDInspector software to have my Canon EF 200mm f1.8 optics perpendicular with QHY9 camera. NOTE! There is nothing wrong with any mechanical part in a camera or the lens, the needed accuracy is just so high, that micron scale errors are seen, for example a protective glass over the CCD-array has a manufacturing tolerance of 1/100mm and that's enough to course problems in orthogonality. (Well... I'm kind of perfectionist and most photographers doesn't see any problems with fast optics, I do.)

Since the Canon EF 200mm f1.8 lens is electronically focused and I'm using it without Canon camera body, I had to modified the lens to it to work. Be warned, the modification image series, behind the link HERE, is not for a weak minded persons!!!

I have made a collection of Tokina AT-X 300mm f2.8 image as well. Images are partly over lapping with the canon collection, since I have used both instruments, Canon and Tokina, to collect the data.
