Message-ID: Hi everyone, I am doing some background research for an article I am writing to be published [eventually] in a nation-wide astronomy magazine [both in USA and UK]. My question to you all is: What is the faintest object you have observed using ONLY the naked- eye? [maybe holding a deep-sky or H-alpha/Beta filter to the eye]. My sources tell me that perhaps Barnard's Loop may hold the record here, or perhaps M81/82? if you have observed such an object, would you let me know, including conditions locations etc., etc..

I think just faintest to the naked eye is sufficient actually. If you can see it, you can see it! Whether it is an extended object of high integrated magnitude or just surface brightness, it will all depend on so many conditions such as eye response, sky conditions etc.. By the way, great work in S&T!!

My name is Mark Reuillard and I received this email probably because I suscribe to IAAC. It is so great to have an email from you show up on my computer screen! I really love your monthly Deep Sky column in S and T Magazine each month and I own and really enjoy your book on Deep Sky Tours. I observe from my backyard in Warren, Maine which is in the Micaost Maine area not far from Camden and Rockport. I own an 8" Light Bridge Dob which I recently purchased from OPT last month and my 12omm ST Orion refractor as well as my Stellarvue 80mm Nighthawk are my collection of astronomical observing tools thus far! I am just starting to get good at CCD imaging using the original Meade DSI CCD Camera and its included Autostar Suite camera control and IP software. Anyway, just wnated to say hi and that I really appreciate your wonderful column and all the information and effort you put inot it for us Deep Sky people. When I get to my home computer I'll send a you a couple of my best CCD images thus far which I got this month. Take care and let me knwo what you think, Clear skies, Mark from Maine ---- Sue French wrote: > Mike, > > I suggest you post your query to the Yahoo group Amastro.
