New camera + filter wheel, new digital focuser and, needless to say, I haven't seen the sky since I received them both LAST YEAR!!!!

Now I am positive: it cannot be simple correlation! It must be "cause-effect": New equipment CAUSES bad weather :C

Ciao Roland from what used to be known as "sunny Italy"!

Frozen Mars

What a result though! It was well worth the time...at least for us, so we get to see this lovely image.

However, I have found a great pair of gloves for our hobby: they are made by Millet a French company that makes mountaneering equipment (here is their US website http://www.milletusa.com/) These gloves leave the tips of your fingers open, but when you don't need to use your fingers anymore there is a nice cover that attaches with a velcro to the back of the glove and that can be pulled up to cover the four fingers and there is also a separate one for your thumb! I find them fantastic, but here it never gets to 9F!!

If you can't find them I can look them up here and send them to you.

Ciao Alan

sbig 10xme versus STL 11000 M

Posted By Gianluca Valentini
Let's not forget that one camera is antiblooming while the other (ST10xme) isn't: Big difference in acquiring and processing data!
If you do not calibrate your exposure time wisely in order to avoid large blooms, these may indeed "hide" some data and, while you can remove the blooms easily via software, there is no way to retrieve the data that was behind them!

Cheers
