Nebula filter for increasing contrast; also suitable for use with smaller telescope; 1.25 inch filter thread; Astromania uhc filter is individually inspected and proudly inscribed with percentage of light transmittance of O-III and H-beta emission lines
Many objects only first become visible at all when using an UHC filter; but also; highlights such as the Orion; Lagoon or Swan nebulae; show a whole new side to them
As many celestial objects; such as nebulae; radiate at other wavelengths; a considerable increase in contrast can be achieved by this; the background sky appears darker and all at once; faint details become visible
The new astromania off axis guider is the lowest profile off axis guider that we know; despite this no compromise has been made with the function and operating comfort of this versatile off axis guider; mechanical flexure between main and guiding telescope can possibly ruin the tracking accuracy if you use an off axis guider
1: Only off axis guider that can be used between coma corrector or field flattener and dslr camera no leaving tolerance distance between camera and corrector 7: Off axis guider provide space for filter wheel or filter drawer when using cooled ccd camera
