For precise focusing: flip mirror makes easy to find exact focus point and also correct position for astrophotography; small black box has a moveable flip mirror which shunts light path 90 degree upwards; alternatively lets it pass through unhindered
Always sharp: If tilt mirror to 45 degree position; object will appear in eyepiece and precisely focus it as usual; helical focuser on flip mirror lets to make eyepiece and camera exactly parfocal; this means elements will be in focus at the same time
No finder is provided with webcams or astronomical CCD cameras for position object on chip; only by taking test exposures may achieve both sharp focus and correct object position; flip mirror help to be centred and focused remotely on chip via eyepiece
The Astromania LRGB Filter Set includes four filters; 1.25" luminance Filter; 1.25" Red Filter; 1.25" Green Filter 1.27" Blue Filter; this LRGB filter set allows you to use your monochrome CCD camera to put together high resolution colour images
The LRGB set features dichroic glass filters designed for maximum transmission; the color filters have an IR-blocking coating; and all filters are parfocal to eliminate the need for refocusing between exposure sets
