TS Imaging Star 102mm f / 5.1 - 6-element Flatfield APO Astrograph

TS 102mm f / 5.1 Imaging Star APO astrograph - aperture 102mm / focal length 520mm



Bright 6-element APO with color-pure FPL-53 lens - fully illuminated and corrected image field for camera sensors up to 42mm diameter


IMAGING STAR Apo Refractor Telescopes Telescopes have been developed for the dedicated astrophotograph. Lens and corrector are optimally matched for best results on the axis and in the field. This 102mm ImagingStar Apo offers with f / 5.1 an enormous light intensity. In a direct comparison to an APO with f / 6 you reach with this Apo the same saturation with approximately 70% exposure time.

The APO offers a completely corrected and illuminated image field with approx. 42mm diameter. We recommend it, for example, for owners of uncooled DSLR cameras, since the noise can be kept very low by the moderate exposure times. The APO is, of course, also suitable for CCD cameras with high-resolution sensors.

Benefits of TS Imaging Star APO 102mm:

- 102mm aperture - light f / 5.1
- FPL-53 triplet lens from Ohara (Japan) for a picture free of color aberrations
- Newly designed 2.5 "tooth / drive extension with 1:10 support for direct screwing of the camera
- Fully corrected and illuminated image field for APS-C format and larger - up to 42mm diameter
- 360 ° rotation for optimal positioning of the object on the chip
- CNC level prism rails for optimum attachment
- Sturdy aluminum case for transport and storage with space for accessories
- retractable dew cap - overall length for transport only 400mm

The adaptation of the camera:

The camera is connected via the M48x0.75 thread. The distance from the thread to the camera sensor is exactly 55mm. You just need the T-ring (see accessory recommendations) and the camera and you are automatically at the correct distance.

Delivery:

TS Imaging Star 102mm f / 5.1 APO
CNC pipe clamps
2.5 "Tooth / drive Okularauszug
Adapter to M48x0.75 connection thread with 360 ° rotation possibility
Aluminum transport case

The 2.5 "eyepiece extract:

The newly designed 2.5 "R & P eyepiece extractor holds even heavy cameras without tilting, which has been specially designed for the use of the camera, with the help of a shifter screw on the base You can also fix the position of the extension tube by means of a knurled screw on the upper side.

The M48 connector for the camera is attached with a dovetail on the extension. It allows a 360 ° rotation of the camera.

Technical specifications:

Opening: 102mm
Focal length: 520mm
Opening ratio: f / 5,1
Lens: 102mm FPL-53 APO Lens 3-element with air gap
Corrector: 3-element corrector fixed built-in - diameter 48.5mm - correction and illumination up to 42mm diameter
Eyepiece pullout: 2.5 "rack and pinion
Weight: 4.5kg (optical tube with clamps)

The 3-element corrector for perfect correction of the field:

The multi-compensated 3-element corrector is fixed and located at the optimum distance from the lens and the camera. The free opening of the corrector is 48.5mm. The corrector is temperature-compensated and tension-free, like the lens. Even at minus degrees, the image quality remains constant.

Visual observation with the ImagingStar APO:
Due to the relatively short distance from the corrector to the focus, the APO is not suitable for use with normal 1.25 "or 2" zenith mirrors. Nevertheless, the Apo also offers visually impressive performance thanks to the large corrected image field. We offer the observers a short adapter flange with a zenith mirror which is clamped directly to the extension, instead of the M48 adaptation (TSIS-ZS1).
