CG-5 and C11 - ok for short exposures?

Posted By Ivan Gastaldo

John, indeed, that is quite a load for a CG-5. I doubt you would be able to get past 30secs without trailing. You could use focal reducers/correctors to bring down the magnification, maybe allowing you to extend a bit the exposure, but IMHO 30secs would be your limit, if your mount can handle it... but in all reality the C11 is way too bulky/heavy for it.

Great shot Jason! 8)

I know what you mean about the gradients, and no, a longer dew-shield or anything like it won't have much effect on them, since the problem is in the sky itself... (LP sucks!)

Have you tried to use something like the IDAS LPS filters...? They might help you fight LP, even though we all know that DARK SKIES is what we really need for DeepSky imaging.

Clear skies, and keep it up! wink

Thanks Rod, I did not know about this settlement, but I'm happy to see this thing has ended...

What I'm wondering though is, what's next? 8)

WSP--What to wear

Posted By Ivan Gastaldo

Alex, it is hard to say, as we could get hit by a cold front and slip into the 50s-60s at night. During the day you can almost be sure we should be around 70s-80s...

Just make sure to bring something to keep you warm at night. I'll be in a tent, so it will be probably colder for me than for you, but then again, WHO plans on sleeping at night? wink

I guess as far as sleeping goes, a sheet and a flannel blanket should be enough...
