{"title":"Telescope field flatteners and correctors","description":"\u003cp\u003eA field flattener, or field corrector, for telescopes is an optical tool used to correct the field curvature of instruments, particularly refractors. Even if the image is sharp in the center, stars and objects at the edges may appear blurred or stretched. The field flattener solves this problem by making the image plane perfectly flat.\u003c\/p\u003e\n\u003cp\u003eThis accessory is essential for astrophotographers and visual observers who want to preserve the sharpness of stars across the entire field of view. It improves edge performance and produces high-quality wide-field images with round, perfectly defined stars across the entire sensor or eyepiece.  You can also complement your equipment with f\u003ca href=\"https:\/\/istronomyplus.com\/collections\/reducers-red-flat\" target=\"_self\" title=\"\"\u003eocal reducers\u003c\/a\u003e, \u003ca href=\"https:\/\/istronomyplus.com\/collections\/coma-correctors\" target=\"_self\" title=\"\"\u003ecoma correctors\u003c\/a\u003e, or \u003ca href=\"https:\/\/istronomyplus.com\/collections\/adc\" target=\"_self\" title=\"\"\u003eatmospheric dispersion correctors (ADC and EADC)\u003c\/a\u003e to obtain even sharper and more accurate images.\u003c\/p\u003e\n\u003cp\u003eWhether you are an astrophotography enthusiast or a demanding observer, the field flattener for telescopes optimizes the accuracy of your observations and the quality of your images.

A flattener \"levels\" the optical problems in the image field such as coma and astigmatism and leads to a similarly perfect image as on the optical axis itself.

The SCA T-Adapter center loads your camera in the drawtube\/visual back with a simple threading of a compression ring forcing the built-in rubber rings outward radially, thereby centering the camera in the drawtube\/visual back for optimal installation.\u003c\/p\u003e\n\u003ch4\u003eSCA Eliminates Drawtube\/Visual Back Slop\u003c\/h4\u003e\n\u003cp\u003eAll drawtube\/visual back have manufacturing tolerances. And it requires larger diameter to accept various eyepieces and adapters. When the camera adapter is inserted, the gap between the drawtube\/visual back and the inserting device became a slop problem. The rubber rings in the SCA expand radially according to users own adjustment to fill the gaps. This makes your camera seats firmly in your drawtube\/visual back becoming part of your telescope for a secure and repeatable installation.\u003c\/p\u003e\n\u003ch4\u003eSCA Eliminates unstable locking from thumbscrew or unified compression ring\u003c\/h4\u003e\n\u003cp\u003eThe optical axis is shifted when the inserting device is locked in by thumbscrew. In some cases, some poorly made unified compression ring can cause unstable tilt when locking in the drawtube due to loose tolerances between the compression ring, inner groove, and the uneven tip of the locking thumbscrew in a drawtube. The SCA T-Adapter adapts your camera without using the thumbscrew or the unified compression ring.\u003c\/p\u003e\n\u003ch4\u003eSCA Accepts the Imperfection of a Drawtube\/Visual Back\u003c\/h4\u003e\n\u003cp\u003eSmall imperfection inside the drawtube like dents and scratches, the rubber rings fill the gaps and faithfully centers your camera in the tube. In addition, even if the drawtube is slightly deformed in diameter, egg-shape, the rubber rings in the SCA will compensate the differences and faithfully centers your camera.\u003c\/p\u003e\n\u003ch4\u003eShort SCA Profile Prevents Oscillation\u003c\/h4\u003e\n\u003cp\u003eShort profile design keeps the installed camera stable from low frequency oscillation transferred from the telescope in a windy environment.

When using a DSLR and a refractor between f\/5.5 to f\/6.5 the field is flattened across the entire sensor. When using small chips like popular 4\/3rd's or 1\" size sensors refractors up to f\/7.5 will not experience any change in focal length Requiring a standard 55mm of back focus, this flattener is perfect for any DSLR imager. No additional extension rings are required. With 38mm of clear aperture remove the chance of vignetting and is well suited for APS-C and smaller sensors. With the optional 48mm adapter a clear aperture of 42mm is provided. A 44mm Clear aperture when the optional 48mm T-Ring adapter is used.

If it needs to be extended, the adapter can be screwed down to reveal the M54 × 0.75 male thread, and the back focus becomes 81.5mm.

This has been accompanied by increasingly specific combinations of one instrument, due to the very wide variety of imaging accessories to be adapted to the focus.\u003c\/p\u003e\n\u003cp\u003eIn order to simplify and rationalise, Takahashi has designed a universal field corrector: the FC\/FS MFL \"multi-flattener\" 1.04x. Neutral in terms of magnification ratio (1.04x), it is intended for all refractors equipped with a Fluorite doublet lens, i.e. those of the FS and FC ranges, new and old models.\u003c\/p\u003e\n\u003cp\u003eThe design of this corrector has enabled all of the previous correctors of these refractors to be upgraded and adapted to the constraints of today's digital imaging. It has resulted in a better correction of field flatness and a drastic reduction of blue and red halos, making it possible to obtain images of flatter and more pricked stellar fields, even on older telescopes such as the FC-50, FC-65, FS-102 or FS-152.\u003c\/p\u003e\n\u003cp\u003eAlthough the corrector is common, it must be used in conjunction with a photo adapter (CA) specific to each FC\/FS telescope. The purpose of this ring, of different length for each model of telescope, is to obtain the backfocus necessary for optimal correction of the field of view at the focal plane. There is therefore a camera adapter for each refractor that is compatible with the corrector.\u003c\/p\u003e\n\u003cp\u003eIMPORTANT!

The optimal backfocus of each telescope is achieved by using an M72 extension ring specific to each model : #51L for the TOA-130, #51S for the TOA-150.

The optimal backfocus of each telescope is achieved by using an M72 extension ring specific to each model : #51L for the TOA-130, #51S for the TOA-150.

This change is a real challenge for conventional refractors, most of whose lenses have been designed to best cover the APS-C format. Although the Takahashi FSQ-85EDX is designed as a Petzval quadruplet, the full-format sensor coverage was not perfect and the edge of the field suffered from a slight astigmatism typical of this optical system. Takahashi offers a dedicated corrector to correct this defect and thus offer results close to those of the FSQ-106ED. The field is perfectly corrected on a diameter of 44 mm. The flattener causes the focal length of the FSQ-85EDX to be slightly increased (by a factor of 1.01x) from 450 mm (F\/5.3) to 455 mm (F\/5.4).\u003cbr\u003e\u003cbr\u003eThe flattener has a M72x1 male thread on the telescope side and a M54x0.75 female thread on the camera side.
