SV179 red dot reflex viewfinder simple, affordable, and effective red dot sighting device makes aiming your telescope.

• UHC filters or light pollution reduction filters are designed to selectively reduce the transmission of certain wavelengths of light;especially those produced by artificial light
• Sky background is darker;and contrast of emission nebulae are noticeably improved;the perfect filter for viewing nebula from light polluted skies;or for boosting the contrast of nebula from dark sky sites
• Due to its ability to produce exceptionally sharp and clear images;this UHC filter is considered one of the most popular astronomy accessories;it can be used not only for celestial observations but also for astrophotography
• 1.25'' barrel diameter simply attach to eyepiece cased in a sturdy transparent case;standard filter thread for 1.25" eyepieces and other accessories
• Optical glass lens;aluminum frame;significantly reduces light pollution;great for city and suburban observation

SV605CC is a 1-inch color deep space camera with 3.76um pixel size, better resolution and 80%+quantum efficiency. It can get good imaging in light polluted environment with double narrowband filters.

Cooling System-Thanks to the two-stage TEC cooling,the SV605CC can lower the CMOS sensor temperature to 30 degrees Celsius below amboent temperature,which can greatly reduce dark current generation anf sensor noise even during longer exposure times.

Support system-SV605CC camera works with Windows,Linux,Mac OS,Chrome OS and Raspberry Pi systems by running AstroDMx Capture. For Windows system,Also support Sharpcap,N.I.N.A,TheSkyX and other softwares run throuth ASCOM platform by suing ASCOM driver.

The Bayer pattern of the SV605CC is GRBG

Notice: The SV605CC has completed the product change to optimize the horizontal stripe, and the S/N serial number of the new product has been changed to S/N(B).

• 0.5x focal reducer cuts the telescopes focal length in 0.5 times of original's to get a wider field of view
• Fully anti-reflection coatings on all air-glass surfaces for increased contrast
• The focal reducer is great for visual use for a bigger FOV and is indispensable when CCD imaging
• Fully metal structure design;both the ends of the interface part is 28.5x0.6 thread
• Directly connect the interface to the eyepiece;there is a very good performance in both visual and photography
