  1. I’m selling my Clement Focuser, a patented, highly engineered and accurate imaging focuser for SCT telescopes, capable of taking RoboFocus (also available at separate cost). This Clement Focuser, made by Don Clement in the USA, was fitted to my 12" Meade SCT, now sold. I’ve moved to refractors only hence reason for sale. This Clement Focuser was mainly used by me with the hand focus knob, is highly accurate for close-up lunar and planetary imaging, and took heavy filter wheel and cameras with ease. The RoboFocus (for sale separately at additional cost) fits easily onto the Focuser and operates through an RS232 connector. This Clement Focuser was recently returned to Don Clement in the USA for final check (total cost of postage and customs $250), works perfectly and is in same condition as when purchased. It has only ever been lightly used. Front plate to back plate when fully extended is 90mm; front to back when fully closed 38mm. Includes rear SCT screw-fit mounting plate which fits Meade and Celestron large SCT thread. Front fitted with 2" brass compression ring. Weight of Focuser is 1145g. Selling the Clement Focuser inc. UK mainland delivery for £500.00. Contact me for separate info on the RoboFocus unit.
  2. Yes, I believe it’s also a field flattener (search the Optec NextGen website for detailed information which is very comprehensive - ‘it is also excellent at correcting the optical problems like spherical chromatism and optical curvature that are common in these telescopes’). I used it on the Meade 12", I once owned, for galaxy imaging with the SXVF H9C camera, greatly reducing the imaging time. Now SOLD.
  3. Optec NGW 0.5X (Next Generation WideField) telecompressor for sale, increases the effective speed of the Meade and Celestron Schmidt-Cassegrain telescopes from f/10 to f/5. This 1/2 times reduction in focal length allows for 4 times greater field area and 1/4 reduction in exposure time for extended surface objects such as bright nebulae. The system is optimized specifically for f/10 Schmidt-Cassegrain telescopes to allow for correction of the field curvature and spherical-chromatism that afflicts these types of instruments. At f/5, the maximum corrected field has a diameter of 17.5 mm at the image plane which makes the optic suitable for CCD cameras with imaging chips of the same diagonal dimension or smaller. Fitted with OPTEC NEXTGEN Mount Plate for Starlight Xpress SXV H9 T-THREAD CAMERA. NextGEN CCD Camera Mounting Plate for Starlight Xpress SXV H9 T-Thread camera. Designed for use with NextGEN MAXField 0.33X, WideField 0.5X Telecompressor Lenses & Ultra WideField Reducer 0.7X. Thread type: T and Backfocus Distance: 1.67". Also supplied with separate camera mounting plate and allen key (see pic 3). I no longer own a Schmidt-Cassegrain so this telecompressor and mount plate are surplus to requirements. Item comes in original cardboard box. Payment by personal cheque (item will be despatched by PO signed for once cheque has cleared) or by cash with personal pick-up. Sale within UK mainland and price includes mainland postage via signed for delivery to recognised postcode. For Sale at £100.00 inc mainland UK delivery, but open to sensible offers

True Technology six-position 1.25” powered Custom-Wheel for sale with hand controller and cables (power cable fits cigar-socket). 1.25” filters and nosepiece adapters are not included (the wheel can take either 1.25” or 2” nosepieces). Filter wheel has 6 filter positions plus one black position for taking dark frames. There is slight perishing of foam seal towards central axle on housing (see images) but does not affect performance and can easily be replaced. This powered wheel is NOT software driven but moved by joystick on the hand controller. Payment by personal cheque (camera will be despatched by PO signed for once cheque has cleared) or by cash with personal pick-up. Sale within UK mainland and price includes mainland postage via signed for delivery to recognised postcode. For sale at £95.00.

  6. Starlight Xpress SXVF-H9 mono camera, boxed with power pack/cables Purchased by me from new, this rarely used SXVF-H9 mono camera comes in original foam lined cardboard box, with all original cables, one additional longer power cable (purchased separately from Starlight Xpress), UK power supply, 1.25” nosepiece and original software CD. Power supply casing has slight crack to plastic housing, but works perfectly. NOW SOLD.
  7. I placed a motorised True Tech 6 filter 1.25" wheel on UK Astro Buy & sell today if interested.
  8. All sorted. Even managed to get the ancient and wonderful Artemis 11002 running smoothly via Maxim DL.
  9. Hi William Diffraction got back to me on the forum. Procedure (as you suggested) is to remove all old Diffraction software however once the upgrade key has been purchased you then have to upload the demo version of DL v6.2 (not the full version). On running the demo version load the attached .txt file from Diffraction’s email and it populates the User Registration panel with the required info. Thanks for your help.
  10. I’m attempting to reinstall all my astro software on a Windows 10 laptop after the previous dinosaur (XP) gave up the ghost. The only problematic software appears to be Maxim DL. I have the original Maxim DL v4. something CD and a plethora of License Key upgrades purchased over the intervening period. Today I also purchased a current upgrade key (on checking the Diffraction website I found I was eligible for a reduced price upgrade). Having installed the original disk onto the new laptop, I’m asked to fill in the User Registration details, however none appear to work. Has anyone else resolved this issue. I’ve also posted on the Diffraction forum, with no luck as yet.

    JTech Designs

    I recently specified a custom tube for a Takahashi refractor with JTech Design, having seen a thread on here. Well, it arrived today and I’m very impressed. Its beautifully engineered with an anodised finish, with a front thread to take 2" filter and two locking knobs at the rear (camera) end, all for a price which beats the official Tak components and it is better made. John at JTech communicated well by email all the way through the production process, thoroughly recommended.
