TS-Optics CCD telecompressor for Ritchey-Chrétien and other F/18 to F/8 telescopes
The TS telecompressor CCD47 was developed for reducing the focal length of RC (Ritchey-Chrétien) telescopes. Practical tests have also shown an excellent suitability for all telescopes with flat field, like apochromats with built-in corrector lens, Celestron EHD or Meade ACF telescopes, thus the most flat-field telescopes. We especially recommend the compressor for the GSO / TS Optics / AstroTec Ritchey-Chrétien telescopes.

The features of the CCD47 telecompressor:
Barrel size is 2" - easy connection to all focusers with 2" receptacle
With thread for 2" filters at the telescope side
Camer aconnection via M48x0.75 thread
Optimal working distance from the connection thread: 85 mm to the camera sensor. Between 70-90 mm, the results are very good.
Reduction by 0.67x - an RC with F/8 changes to fast f/5.3. A telescope with f/10 still turns into f/6.7. The exposure time will be more than halved!
An illuminated image field of 29 mm allows using all camera sensors up to APS-C format.


Adapter recommendations:
With the long working distance, adaptation of all common cameras, no matter whether CCD or DSLR, is possible without any problems. Some examples of applications:
DSLR camera - adaption via M48: TSVF230 and then the matching adapter from M48 to the camera, like the SKM48-EOS for connecting a Canon EOS
CCD cameras via T2 connection: two adapters are possible for reducing the M48 thread to T2:


TSFA2 - adapter to T2 with 38.2 mm length. This is used for bridging optical path.

TSM48-T2 - a short adapter with only 3.5 mm length. This is applied if accessories like off-axis guider and filter wheels should be used.
Barrel size:2"
Filter thread:2" filter thread at the telescope side
Camera connector:M48x0.75 thread (male, 5 mm long)
Body length:29.2 mm (w/o male thread)
Working distance:Between 70-90 mm - optimal results are achieved at approx. 85 mm
Factor:0.67x
Clear aperture:44 mm
Coating:Best possible coating - guaranteed no reflexes or ghost images
Illumination at f/8:D=29 mm fully illuminated

Testimonial and example image of our customers Florian Stürzer and Simon Stich aka galacticdudes
The two dedicated amateur astronomers from Grafing tried out the RC TSRC6M with the reducer CCD47, using a modified Canon EOS 60D. A test report is available as PDF here, we show a successful picture here:


Cone Nebula (NGC 2264)
Photographers: Florian Stürzer and Simon Stich
Telescope: TS 6" RC TSRC6M on mount Orion Atlas EQ-G
Imaging camera: Canon EOS 60D
Reducer: TS CCD47
Filters: RGB and Baader H-alpha 7 nm narrow band filter
Sensitivity: ISO 800/30° for RGB, ISO 1600/33° for H-alpha
Frames: 33x 600 s for RGB and 28x 600 s for H-alpha



Question:
How do you have to measure the working distance?

Answer from Teleskop-Service:
The working distance is measured from the beginning of the connection thread on the housing of the corrector (see example picture):

Auf der Suche nach einem Reducer für meinen Maksutov bin ich über dieses Teil hier gestolpert. Nach ersten Tests kann ich sagen: er passt ganz hervorragend zu meinem Skywatcher Skymax 180!
Die Sterne sind in allen Ecken rund, meine Suche hat ein Ende, kann diesen Reducer sehr empfehlen!
