Shares and cherishes the gorgeous night sky, the everyone’s property.
I observed this scene last night after I had had my dinner. Someone will verify whether this is noctilucent cloud before I can proceed further. Before this, let Spaceweather.com explains what are noctilucent clouds.

Thursday, June 15th, is a special night. En route to Saturn, Mars will pass directly in front of the Beehive. Ready your binoculars or even a telescope now! Red Mars is about 16 times brighter than the surrounding stars. “It’ll look like a red supernova has gone off inside the cluster–a wonderful photo-op for amateur astronomers”, Spaceweather.com said.
Isn’t it a GoTo telescope is capable of tracking celestial objects? Why do I need the autoguiding? ![:-\](http://www.astronomynotes.net/smilies/yahoo_question.gif ":-\"){kind=small}
At first, tracking is just similiar to guiding. For instance in the Autostar Suite from Meade, tracking allows you to define a bright spot (centroid) that it (Autostar Suite) will use to anchor images when combining (stacking) them into one image.
Don’t you find that most of the high end imagers are made of monochrome CCD? If you don’t believe, just take a look on Meade Deep Sky Imager II Pro (DSI II Pro) as well as its predecessor, the DSI Pro. Obviously, both of them are made of monochrome CCD sensor.
Isn’t the picture captured tasteless without any colour? What are the advantages of monochrome CCD over colour CCD?
It’s almost a week since last observation. The night skies this weeks were really encouraging. Of course, I wouldn’t miss the chance to observe the charming sky. However, most of the objects in Tonight’s Best were either blocked by my house or they were just too faint. One of them was 20 in magnitude! This object was impossible for my 8″ telescope. I think I’ll be able to view some brighter objects after I get my notebook for astrophotography. As the sky was very clear, I decided not to observe planet in this observation.
This is very important to every astronomers but easy to learn. Calculating the magnification always helps you to know the current situation and get the best view of the objects. For every celestial objects, there are always the most suitable views (magnification) for it. Let’s back to the topic, I shall discuss the most suitable views in the coming days.
