QuestionWhere can I find coordinates to use with my telescope?Community AnswerThere's a lot of planetarium software available for computers, tablets, and phones. These programs can show you what's in the sky at a given location, date, and time. You can also look at star charts or planispheres. If you want fun objects to look at, consider looking into the Messier objects.

What lenses should I use to get a clear vision of the moon?VISHNU GOKULCommunity AnswerYou can use the 20 mm lens, and if you want to get more details of the moon, use the 12.5 mm. To look at craters, you can use the 4 mm eyepiece.

QuestionI am not able to observe deep sky objects such as Sirius Orion nebula, Aldebran and Pollux through my telescope. I align them correctly through the finder, but still nothing. what can be the solution?Raymond David WhatleyCommunity AnswerYour finder might not be aligned to your telescope. To align your finder, set up your telescope in the daytime and pick a distant object, such as a stop sign at the end of the street. Try to point your telescope at that object and using the surrounding area make adjustments until it is perfectly centered in your eyepiece. Then use the adjustment screws on your finder to adjust it until the object is also centered in your finder. Now your finder is properly aligned. Try using it to find a few more distant objects like the top of a telephone pole or a bird on a branch. Warning: Do not point your telescope at the sun!
