Take your solar imaging to the next level with the Calcium Gen-II 1.25" Unstacked Ca-K Solar Imaging Filter with LPFC. This advanced filter allows you to explore the fascinating boundary region between the sun's photosphere, visible in white light, and the chromosphere, typically observed with narrow-band H-alpha filters. With the Calcium Gen-II filter, you can observe not only familiar white light structures like sunspots, but also the chromospheric network that covers the sun's entire surface. This network is a precursor to sunspot formation and is accompanied by supergranulation cells and Ellerman Bombs. The filter operates at the emission line of calcium at 394 nm, which is in the near UV spectrum. As such, it's crucial to remember that this filter is designed for camera use only, as the human eye is not equipped to safely handle UV radiation. For optimal results, we recommend using this filter with a monochrome camera and mirror telescopes. While many lens telescopes can still be used for calcium observations, unmodified DSLRs may require significantly longer exposure times. All calcium filters necessitate an additional solar filter. The Baader GEN-II package includes a sheet of AstroSolar Photo Film OD 3.8, 20x30 cm (#2459278) to construct your own solar filter, allowing you to start observing without the need for additional purchases. The Calcium Gen-II filter supersedes the older K-Line Filter 1 1/4" (stacked) # 2458355. Thanks to modern manufacturing techniques, this single filter provides superior quality and a narrower half-band width (FWHM) of only 5 nm, eliminating the need for filter stacking. The low-profile filter mount is only 6 mm high when screwed in, making it compatible with standard filter wheels/drawers. For cameras with a 2"-nosepiece, the filter can be used with a filter drawer like the Baader UFC System or a filter wheel. The Baader Calcium GEN-II boasts all the benefits of the new generation of CMOS-optimized Baader filters, including increased contrast, Reflex-Blocker coatings for maximum halo freedom, identical filter thickness for parfocality, blackened edges for reflection elimination, individually coated filters with sealed coating edges, and Life-Coat for a durable, non-aging coating. In summary, the Calcium Gen-II 1.25" Unstacked Ca-K Solar Imaging Filter with LPFC is a powerful tool for any solar imaging enthusiast, offering a unique perspective on our sun's complex and captivating features.

Robelle Calcium Plus is used to raise calcium hardness levels when measures drop below the recommended range of 200-400 ppm. If calcium hardness levels are too low the "soft water" will corrode pool equipment, etch pool plaster, and may cause metallic stains. To raise the hardness level by approximately 50ppm is necessary to add 6.25 lbs. per 10,000 Gal. of pool water.

Robelle Calcium Plus is used to raise calcium hardness levels when measures drop below the recommended range of 200-400 ppm. If calcium hardness levels are too low the "soft water" will corrode pool equipment, etch pool plaster and may cause metallic stains. This is a dry granular product that increases the total hardness in pool water to the recommended range. Directions for use: Test for calcium hardness with a reliable test kit. The desired range for calcium hardness is as follows: Vinyl Pools - 200-300 ppm. Tile and Exposed Aggregate Pools - 200-400 ppm. Marcite, Fiberglass or Painted Pools - 250-400 ppm. If the calcium hardness tests less than the desired range, add this product according to the guide below. Place this product into a plastic bucket already filled with swimming pool water. Do this in a ration of up to 2 lbs. of product per approximate 5 Gal. bucket of water. Slowly pour this solution around the perimeter of the swimming pool while the circulating system is operating. In a 10,000 Gal. pool, do not add more than 10 lbs. of this product per 2 hour period. For 5,000 Gal. pool: to increase by 10 ppm add 7.2 oz., to increase by 20 ppm add 14.4 oz., to increase by 30 ppm add 1.35 lbs., to increase by 40 ppm add 1.8 lbs., to increase by 60 ppm add 2.7 lbs., to increase by 80 ppm add 3.6 lbs., to increase by 100 ppm add 4.5 lbs.
