To good to be true

I thought the arrival of my a new telescope, would bring forth rain. Which it did on Sunday and, since then, the weather has felt more like April than the start of Summer.

On the plus side; I made myself an off axis baader solar filter, using a spare dust cover. The filter is about 3inches diameter and increases the focal length of my 10" from f4.8 to about f16 this is ideal for comfortable solar viewing.

I was lucky enough to get my first views of the Sun on Friday June 5th. I've found the 35mm Celestron Ultima works best, and with my baader contrast boost filter the image is greatly enhanced.
The low magnification 34x, reduces atmospheric heat shimmer, and the contrast is better than through a higher power ep. So you get a nice steady image that is very sharp, allowing you to see plenty of detail in white light.

At the time of my observation (14:05ut) there was a very nice spot group visible, with plenty of limb darkening, and faculae.

I hope to begin drawing the Sun, when I get the chance, and I also want to start drawing DSO's. But I think this will prove tricky as I have not done any astronomical drawing before.

I've yet to view the Moon through the 10", and if the views I had of Saturn are anything to go by. I'll be in for a treat.
