Lost in Aquila (pass the DSCs)
Spent an hour or so fiddly about in Aquila last night, looking for the
mag 11 galaxy there (NGC ?) and the string of half a dozen planetary nebula (NGC 6803, 6804 etc). All these objects are described as visible in an 8" scope in John Stanford's excellent book Observing the Constellations. Transparaency wasn't great, and it was near the brighter Sydney side of the sky, but I couldn't find any of these objects, admittedly not a huge effort made on my part. Part of the problem was sky brightness and a lack of good reference stars for close hoppping. During a previous session in Centuarus I managed to find 3 galaxies without too much trouble, so I'll claim the problem was not complete ineptitude :-) It would have been really nice to have definite way of knowing I was looking in the right spot, then upping the mag to increase contrast and maybe pick them out. I can see the appeal of DSCs. Do you want to spend your time "looking for" or "looking at"? Both valid and fun, IMO. Maybe I just need more aperture :-) Tips and suggestions welcome. Mark PS Part of the problem may have been the glare from Mars, which is soooooooo high and bright at 35deg south :-) |

Lost in Aquila (pass the DSCs)
Hello, Mark,
I like Sanford' book too. Very helpful. I think DSC's are extremely helpful for urban and suburban observers in particular, and also far dark skies unless you are quite skilled or are looking for bright objects. They make a fine addition to a Dob, in my view. Goto, and tracking I find less essential, more like pleasant luxuries. but digital DSC's, sometimes called "push-to," make an enormous difference in finding objects.

A word more on Sanford's book: find the scale of the maps is too small to be
of much help in starhopping but he approximate locations of the deep sky objects is readily apparent the yellow on black markings on the maps. His lists of objects, combined with the mapped positions of these objects, make it useful as a kind of expanded Volume 2 of the Steve Gottlieb's Deep Map 600 (marketed by Orion). Combined with DSC's to find the depicted and listed objects, the result is a very good approach to observing, IMO. Bill Meyers Bill Meyers wrote: Hello, Mark, I like Sanford' book too. Very helpful.

Mark Hang in there. I've seen nights that looked pretty transparent at first glance, but behind a scope, even looking at the brightest "M" objects, I might as well have been under a layer of sheetrock. Marty |

Marty So darned true, from Casper Wyoming, Marty. I'll take steady seeing over transparency anytime; at least, that's what I'm currently claiming. ;^) Best regards, Bill |
