TS Photoline 90 mm f/6.6 FPL 53 Triplet SuperApo Telescope - 2.5" Focuser - 3 different Focus Positions
...High quality Apo, colourfree and with a very good mechanics - for highest demands - no vignetting in the edges
...3 focus positions behind the focuser - ready for Riccardi Reducer, Bino viewing, classical flattener or observing
Developed under the control of TS, this Photoline Triplet Apo with FPL 53 is an optimal telescope for travelling and astrophotography.
Even at highest magnifications, the image rests free of colour while at the same time keeping the perfect field correction. This is one of the best 90 mm Apos. The fast f/6.6 system is not just very transportable and compact, it also stands for short exposure times for astrophotography.The advantages of the TS Triplet Apo 90/600 mm:
- Triplet Apo 90/600 with air gap
- O´Hara FPL 53 for perfect colour correction
- Retractable dewcap - decrease the tubes length to only 450 mm
- very stable CNC rings
- splitable tube - you have tree different focus positions from the focuser
- High precission made 2.5" focuser with 1:10 dual speed - with M63 connection thread
- Huge field of view of up to 5° with a suitable 2" eyepiece
- Phantastic and fast photographic Apo with superb field correction in combination with the optional TS 2.5" flattener or APM/Riccardi Reducer
- no reflexions due to the very good coating
- comes in a rigid case
- High-quality aluminium tube for fast cooling - better than a carbon tube
The TS 90/600 Triplet Apo lens:
The triplet lens delivers an image free of color fringes - it is a true Apo. It also has the best spherical correction possible. The air spaced triplet is installed in a temperature compensated cell.
Even high resolving astro images show no disturbing color fringes around stars.
Photographical use: two focal lengths with one telescope!
Aperture 90 mm / focal length 600 mm /f6.7: The TS 2.5" Flattener provides a fully illuminated and corrected field, even for fullframe cameras. The flattener is being screwed dirctly to the M63x1 inside thread of the focuser. You need to remove 1 tube part.
Aperture 90 mm / focal length 450 mm /f4.9: The reducer, calculated by Massimo Riccardi reduces the focal length and increases the aperture - focal ratio to f/4.9 while at the same time correcting the entire field for APS-C format sensors or KAF8300. Due to the very fast system. You can take photos of faint objects within one night. Even time-consuming LRGB images or narrowband imaging is no problem anymore. You need to remove 2 tube parts.
Observing with Bino Viewer without Glass Path Corrector: Incredible rich field observation with both eyes without glass path corrector which increase the magnification - this offers this TS 90 mm Apo. You will be able to observe large deep sky objects and because of the very low magnification, you will have much light and a big field. Remove all 3 parts for long bino viewers or if you want to use a 2" diagonal or remove 2 parts, if you use a 1.25" diagonal.
The 2.5" focuser:
The large 2.5" focuser guarantees a maximum illuminated field. The focuser comes with an M63x1 thread, ready for the 0.75x APM/Riccardi reducer / corrector or the 2.5" TS flattener. The focuser is superior to most of the Crayford focusers and even with highest payloads. You won´t get any flexion problems.
The focuser also provides a 360° rotation and also a 1:10 dual speed.
