TS-Optics Doublet SD Apo 102mm f/7 - FPL53 / Lanthanum Lens

TS-Optics PhotoLine 102mm f/7 Doublet FPL53 Apo

This apochromatic from Teleskop Service's PhotoLine series offers very good performance in any area of ​​application. By combining FPL53 (Ohara, Japan) and a lanthanum glass element, color correction is achieved that matches that of an FPL53 triplet, with significantly faster cooling. Even at the highest magnification, the image remains free of distracting chromatic aberrations. This means that the fast refractor is not only well suited for astrophotography and wide-field viewing, but also for the moon and planets.

Very fine mechanics guarantees joy with the telescope and universal application capabilities

The new PhotoLine 102mm apo offers, in addition to a state-of-the-art lens, also a mechanical equipment that leaves nothing to be desired. Therefore, the performance of the lens can be fully implemented photographically or visually.

Advantages and characteristics of the PhotoLine 102mm f/7 apo:

♦ 102mm f/7 FPL53 lanthanum glass lens for an image without chromatic aberration

♦ Ball bearing supported focuser with rack and pinion adjustment. The bracket is decoupled from the drawtube fitting.

♦ Oversized draw tube for full illumination even in full frame format.

♦ 1:10 speed reduction for precise focus.

♦ Motorized focus can be adapted.

♦ Thread M68x1 (female) for threaded fittings and 2" / 1.25" for pushed fittings

♦ Internal baffles and very good internal blackening for contrasting images

♦ Retractable spray cap for easy transport

♦ CNC tube rings and GP style dovetail bar in scope of delivery

Astrophotography with the TSAPO102F7:

The Photoline SD-Apo 102mm f/7 is fully suitable for astrophotography, however as with any fast refractor the field needs to be corrected so that even the stars on the edge are round. For this we offer the following options, the correctors are linked in the accessories section.

♦ TSFLAT25DEL 1.0x photoline corrector:

This corrector does not change the focal length. Screws directly to the focuser's M68x1 female thread with the #M68a-M63i adapter. The working distance from the M48 camera thread is 55mm. So adaptation is easy. We will be happy to help you with the adaptation.

♦ TSRed379 - 3" Photoline Reducer and Corrector: This 0.79x corrector reduces the focal length to 564mm and increases speed to f/5.53. The working distance from the M48 thread is 56mm. camera with 55mm flange focal length, simply use an M48 tuning ring with 1mm height.The corrector is screwed onto the M68 connection thread.Illumination and correction are suitable for all sensors up to full frame.
