It's all combined in one lightweight eyepiece sized device. The fully optimized design eliminates the need for any adapters. Imagers can use the same switch to create comparison images without the need to exchange equipment or refocus with short lived features. Outreach astronomers can use the prom vs chrom switch to demonstrate each feature with an extra teaching moment about wing shift going on in fast moving prominences. This highly specialized telecentric lens offers superior field flatness.Įxact filter bandpass will vary based on final telescope application, so QUARK* assemblies are qualified with one element to show best prominences and the other to show best surface contrast (chromosphere). The patent pending QUARK* contains a custom Daystar Instruments 4.2X telecentric barlow lens fully optimized in coatings and optical design specifically for the Hydrogen Alpha wavelength. Just insert in your diagonal, add an eyepiece and view. Includes wall adapter for 110-240VAC including international power plugs.īoxed in environmentally controlled pelican style case.įits all visual and imaging adapters in Quark product line.įor use on refractors of F/4 to F/8**, the user needn't worry about configurations. Requires 2.0Amp 5VDC 10watts electrical power. Paired etalons will be matched to maximize effect of wide vs narrow bandpass.

T-adapter, C-mount adapter or 2" drawtube adapters are optionally available. 22mm clear eyepiece aperture.įits into 1.25" and 2" telescope drawtubes - designed for use on refractor telescopes of F/5-F/8Ĭomes standard with 1.25" female eyepiece drawtube. Specificationsįully self contained solar filter, safe for human eyes and imaging. Imagers can do comparison images and outreach astronomers can demonstrate surface structure and prominences and the science involved in wing shift. Push the slider arm side to side like in an eye exam to see the broad stroked prominences of wider bandpass, then the high contrast of narrow bandpass. Now, observers can enjoy the best of both options in one easy to use tool with no equipment swapping or refocusing of any kind.
