The Artesky 1.0x variable field flattener is perfectly compatible with refractors from 80mm up to 155mm, allowing you to have a corrected field up to the edges even with large sensors such as FullFrame. The peculiarity of this universal flattener is the fact that it has integrated a variable micrometric adjustment system of the backfocus, this allows you to no longer have to go crazy with fittings and rings to reach the optimal distance for your telescope and your sensor! Lighting and correction up to full frame format Telescope connection via M63x1 thread - adapters for other connections, e.g. M68x1, are available Camera connection via M48x0.75 thread with integrated connector for 2" filter - It is necessary to remove the 3 120° Allen screws to access the integrated filter holder The working distance can be adjusted to the millimetre via an integrated fine adjustment! The corrector can be used on all refractors with an aperture of 80mm and above, up to 155mm (tested) 2-element design with special ED glass No reflections thanks to the complete multilayer and internal blackening An essential part of the corrector is a built-in fine adjustment. By rotating the red knurled ring on the corrector, you can adjust the distance from the sensor within fractions of a millimeter. Once the desired distance is reached, secure it with the locking screw on the side. This way, the optimal distance can be determined by taking test shots with the camera attached, without additional adapters and fine-tuning rings. The camera does not rotate during fine adjustment! The following settings are recommended from the innermost position of the fine adjustment to your camera's sensor: Aperture 80mm / Focal ratio f/6 - 81.2mm Aperture 80mm / Focal ratio f/7 - 80.2mm Aperture 102mm / Focal ratio f/7 - 75.3mm Aperture 115mm / Focal ratio f/7 - 73.0mm Aperture 130mm / Focal ratio f/7 - 69.7mm Aperture 140mm / Focal ratio f/6.5 - 68.0mm Aperture 155mm / focal ratio f/8 - 57.0mm This Artesky flattener has a M63x1 male thread on the side of the telescope. Many focusers already have this thread as standard, for example TS refractors, Tecnosky, Altair Astro and many others Of course, adapters for other threads, such as M68x1, are available. Setting the correct distance is very simple, as shown below. Let's say we have: Refractor with 115mm aperture and F/7 focal length, i.e. focal length of 805mm SLR camera with 55mm distance from M48 thread to sensor The working distance is 73mm according to the table. From this measurement, simply subtract the 55mm (sensor distance). 18mm remains Simply rotate the variable adjustment (red ring) by 18mm outwards, easily adjustable via the distance marking. You are already at the optimal distance and can start taking pictures! ATTENTION: the table shows working distances tested only on some products, other refractors may be compatible but the working distance will have to be slightly varied.
