Our Moon on Monday night
The skies on Monday night were really bad and I questioned myself about why I bothered to make the attempt.Knowing that their was a weather front making it’s way into the area,I chose to set my scope up anyway.The normal set up time for my scope and all the other equipment usually takes about 20-30 minutes not including the scopes cool down time.In case you were wondering why do I want the scope to cool down?.Well,that is easy to answer.The scope has to adjust to the outside temperatures which is known as “thermal equilibrium”.This is to allow the expansion and contraction of the OTA and mirrors,which if ignored will cause unwanted focusing problems and frustration.This cool down can take upto a hour depending on the size of the scope and temperature difference!.Through the course of my observing session,high wispy clouds began to increase until much of the sky had turned into a thin blanket creating a small halo around the moon.After a couple hours the sky had turned completely overcast which put a end to observing for the night.I did however,get some mediocre images of moons southern hemisphere using a Meade DSI(Deep sky imager).This is the first time I have made the attempt using the DSI and to put it simple…I honestly like the LPI(Lunar planetary imager)better for this application,even though it wasn’t a real fair test for the DSI.If the weather forcast are as good as they predicting for tomorrow night,then I will have the chance to give the DSI another try at the full moon,which in October is also known as the “Hunters moon”.This full moon is going to largest of the year.No,it hasn’t grown in size but,because it will be at it’s closest point for the year at 221,676 miles from earth which is known as perigee.Here is how the FarmerAlmanac describes it;Full Hunter’s Moon – October With the leaves falling and the deer fattened, it is time to hunt. Since the fields have been reaped, hunters can easily see fox and the animals which have come out to glean.I couldn’t put it much better than that!!!.
