![]() ♦ No corrector: If you do not want to use a corrector, because for example the moon or (with front filter) the sun is the object, then you need, if also no star diagonal is to be used, in addition to the adapter to T2 or M48 still appropriate extension tubes. For the adaption to a DSLR camera, you can need (for example): We recommend the reducer for cameras up to APS-C sensors. The working distance from the T2-thread is 61 mm. The reducer is directly clamped by the 2" receptacle. ♦ TSRed279 - 2" Photoline reducer and corrector: The 0.79x corrector reduces the focal length of the apochromat to 379 mm and increases the speed from f/6 to f/4.74. For most cameras, there are already ready-made adaptations for the M48x0.75 connection with this distance. The working distance from the M48 thread is 55 mm. The focal length is reduced to 384 mm and the focal ratio is improved to fast f/4.8.įor the connection to the apo you need the adapter # M68a-M63i, with this the corrector is screwed directly to the M68x1 connection thread. ♦ TSCFRED80 - 0.8x corrector for 80 mm f/6 triplet poss:The corrector is calculated for triplet apos with 80 mm aperture f/6 and offers the optimal performance. If you are using a camera with 55 mm flange focal distance, such as an SLR with T-ring, you will also need a 10 mm M48 extension # TSVF210. The working distance from the M48 connection thread to the camera sensor is 65 mm. For the connection to the apo you need the adapter # M68a-M63i, with this the corrector is screwed directly to the M68x1 connection thread. ♦ TSFlat25DEL - universal 2.5" field corrector without focal length change: The corrector is suitable for all sensors up to full frame format. For this, we offer the following options which are linked in the accessories section. However, eyepieces with more focal length or true field of view can also be used, because the vignetting does not start abruptly.Īstrophotography with the TLAPO804:The Photoline 80 mm f/6 apo is suitable for astrophotography without restrictions, but, as with any fast refractor, the field has to be corrected for keeping the stars nicely round even at the edge. We recommend a zoom eyepiece, as it is more convenient and its field stop will usually not be larger than the clear aperture of the Amici prism, thus avoiding vignetting.Ī tested combination of Amici prism and eyepiece on the one hand and tripod with tripod head on the other hand consists of the items TSA245 and HypZ as well as FGX3 and TSLH-20, which are all linked in the accessory recommendations. If an Amici prism is used instead of the zenith mirror, you get a spotting scope for landscape or bird watching. Visual use - spotting scope and astronomical travel telescopeThe TLAPO804 can be configured with a star diagonal mirror, eyepiece and finder to form a lightweight telescope for travel, and a long-focus wide-angle eyepiece can be used instead of the finder. ♦ Each ring has 3 M6 threads (female) on top side, one of them in the middle, two in 30 mm distance at the side ![]() ♦ High-quality CNC rings and GP style dovetail bar with photo thread connection ♦ Modern and multi-coated 3-element lens with FPL53 as APO element ♦ Retractable dewcap - only 37.5 cm transportation length ♦ M68x1 female thread on the connection adapter, to get to the thread, 3 grub screws must be loosened. ♦ High-quality CNC tube with internal baffling and very good internal blackening - no annoying stray light ♦ 1:10 dual speed system for ultra-precise focusing ♦ Oversized drawtube with 60 mm clear aperture for full illumination even if full-frame sensors are used. The support is decoupled from the drawtube drive. ♦ Rack-and-pinion focuser, plain bearing mounted. The advantages and features at a glimpse: This is not the case for the Photoline 80 mm f/6 apo. Here, savings were often made in the wrong place. The fast focal ratio of f/6 not only keeps the refractor very short, it also provides short exposure times for astrophotography.Īstrophotographic results obtained with this telescope on AstrobinHere you can find some astrophotographs made with this telescope model: Link to Astrobinīest mechanics ensure an excellent image quality over years and success in astrophotographyEven the best optics can be used successfully only if the mechanics is right. It is one of the best and fastest 80 mm apos we have seen. A perfect travelling apochromat - for observation and astrophotography Under the lead management of Teleskop-Service, this high-quality Photoline triplet apo with FPL53 element from Ohara (Japan) came to life as optimal travelling apochromat.Įven at higher magnification, the image has no annoying chromatic error, with excellent correction at the same time.
