Another big question. The Moon has always been the bane of deep sky observers. But you are using an iTtelescope with an advanced CCD camera and a variety of onboard filters.

iTelescope.Net billing systems are set to deliver a real Narrowband bonus with the ‘Moon Discount’ during these periods for many members. Don’t let the moon slow you down or scare you. Just show wisdom in your target choices. Try to select a target at least 60 degrees away from the Moon.

 A nearby bright moon can effect your session in several ways. The telescope may not be able to find a guide star or focus properly. Moonglow can also washout an image if it is too close, making the saved calibration data ineffective or cause reflections within the telescope optics. We suggest you give the moon at least 60 degrees clearance. This is where a good planetarium application comes in handy.

Using a red filter for b&w exposures can restore your contrast levels and negate the moonglow somewhat. Stick to the bright galaxies, emission nebula, globular clusters and targets opposite the moon in the sky if possible. Digital images are a wonderfully forgiving and flexible medium.

Narrowband filters are mostly  immune to moonglow.
