4 what is the function of sv210?

Without rotating the objective lens, the shooting angle of the camera (SLR camera and astronomical camera) can be adjusted according to the shooting needs. Our caa-m63 is suitable for our SV550 80F6. At the same time, it can also be compatible with the astronomical lens barrel of M63 * 1 threaded grid astronomical focusing seat.

what is the effect of matching the two with sv550?

The combination of the two will make the picture closer to reality, have better imaging effect, be more conducive to obtaining more details, and be of great help to shooting.

what is sv550?

The SV550 APO Triplet refractor with 80mm aperture and fast f/6 focal ratio, a great travel telescope for observation and astrophotography.

what is SV405CC?

SV405CC is the deep space camera of SVBONY brand. It is designed with SONY IMX294 color CMOS sensor.

sv211 bright spots

sv211 is a comfortable and convenient carrying handle, easy to carry, you can take it off and install it on a tripod at any time.
There is also a neat integrated saddle designed to accept SV198 or other brands of boot range and viewfinder range
Full CNC integrated finishing anodized aluminum, hard metal texture, firmly fit on your telescope.
Compatible products OTA: SV503 (70F6 80F7) SV550 (80F6), make it more convenient for you to use

sv198 bright spots

Versatility
The 207mm focal length SV198 guide scope adapts the Modular design, which permits it to attach the normal standard 1.25’’ erect diagonal or illuminated eyepiece easily, needless the Barlow or adapter. the mainstream CCD camera like ZWO or QHY guide scope match well with SV198.
Mechanically light elimination
The precise CNC machining promises precision and product quality, and the Internal blackening process + the elimination of light processing of thread on the inner wall of the lens barrel, which provides the double guarantee. Multi-layer broadband AR coating and 2-Elements/ 1Groups lens optical structure are optimal at their level.
Focus design
High-precision + long-thread focusing design: 38mm pull-out coarse adjustment ensures sufficient focusing range; 11mm double-spiral focusing ensures focusing accuracy. Can carry 3kg guide scope setup.
The friendly design mount
Universal 6-point guide ring, easy coaxial adjustment. Hollow carved dovetail plate, convenient to adjust the fixed position according to the load.

Note:

If you need to complete deep space photography, SVBONY suggests you add a guide camera,Like This:

Deep sky photography OTA
The SV550 APO Triplet refractor with 80mm aperture and fast f/6 focal ratio, a great travel telescope for observation and astrophotography.

4 extinction bars are designed to meet your ultimate pursuit of extinction.
The structure of the triplet apochromatic optics effectively improves the blue-edge chromatic aberration at the edge.
180mm hollow-out super-long dovetail plate, which is convenient for customers to quickly balance the system.
CNC double hinge opening hoop, easy to disassemble and install (built-in white felt, does not damage the outer wall of the lens barrel).
Combining the SV550 Telescope with the SV405CC deep space camera, field flattener, CAA, soft case, and handle bar enables deep sky photography.

Apochromatic triplet uses a series of three lenses. It provides better correction of aberration and significantly reduces dispersion. It reduces chromatic aberration, and it corrects for two wavelengths to reduce spherical aberration. The apochromatic triplet objective provides high-quality, sharp and high-contrast images.

Focal Length: 480mm

The focal length is 480mm, suitable for deep sky observation and photography, for galaxies, nebulae, star clusters and other deep sky objects.;
2.5" 1:10 Dual-speed Focuser

The gear ratio of the dual speed 2.5-inch toothed focuser is 1: 10, which makes it easy to achieve accurate focus. The dual speed focuser can provide two focusing speeds by using a set of co-axial knobs, for fast focusing and fine focusing. ;
Elimination of Stray Light

Blackened inside and knife-edge baffle are for reduction of stray light and improvement of image contrast. ;
2-inch & M63x1
Vixen-style Dovetail

For astronomy enthusiasts, it is a very challenging and interesting thing to match various accessories and telescopes to photograph target objections. This can give full play to your imagination and creativity. On our social platform, there are often many fans sharing their collocations, which is really pleasing. So what can we match the SV550? Today I want to share with you two options. If you have better ideas, welcome to share them with us.

Let me first introduce the product highlights of SV550：
Point 1: The three-piece APO apochromatic objective lens structure is adopted, which significantly improves the image quality of the captured image (15.8% increase by the spectrometer measurement)
Core selling.

Point 2: 2.5-inch magnesium alloy dual-speed toothed focusing seat is used to reduce vignetting when connecting to a full-frame camera and reduce the load weight of the supporting platform.

Point 3: extreme extinction, the interior of the focusing seat + the inner wall of the lens barrel with multiple light barriers.

Point 4: The dedicated 1x flat field mirror is launched simultaneously to meet the ultimate pursuit of image quality for deep space photography users (the synchronization accessories also include CAA handles and portable storage bags).

If you want to use these equipment for photography, you can consider these combinations.
