Hello Anthony....

Hope you had a great xmas!
Welcome to IIS!
Nice shot of the horsey! color balance is looking good! as well as the guiding.
Set up the scope last night for a go at M42 but alas that band of cloud does not want to move away!
I usually shrink my pic to about 800x600 px and then save a copy for posting (jpeg) and compress from anywhere from 5-10 till the pic is just under 150k in size. In photoshop its good as it tells you the size on the bottom of the form as you move the slider..
If you want to post a higher res pic you can always ues the IIS ftp server. Heres the page to get you going and contact link on the bottom...
