Bad Seeing

Is that like BAD Robot no but when you set up for a nights imaging then decide that an imaging session is out of the question because the quality of viewing has been impaired by local burn offs, you remember that sometimes going back to basics within your window of opportunity can be enjoyable



With Antares, a first magnitude red giant some 300 times larger than our sun. from theremove 1 degree west to find M4, one of the best globular clusters in our sky. then move 3 degrees northwest to another globular cluster M80. Back to Antares and travel approximately 6 degrees east to M19, a globular cluster of medium density but quite bright.From M19 move approximately 3 degrees south to M62 a large and very bright globular cluster with a reddish centre. Now go back to Antares and move down the back of the scorpion to the bend in its tail, where you will find NGC 6231, a fairly large open cluster. When viewed through a pair of 10 x 50 binoculars, and with a bit of imagination you can make out the form of a lizard. This cluster has several bluish-white super giants. Now move 1.5 degrees north to find NGC 6242, another open cluster and a good binocular target with a bright red-orange star near the southern edge move 3 degrees northeast to NGC 6281 which is similar in size but with fewer stars. Another 9 degrees east and slightly north to M7. also designated NGC 6475 and sometimes known as the Ptolemy Cluster, is an open cluster of stars in the constellation of Scorpius. The cluster is easily detectable with the naked eye, close to the "stinger" of Scorpius. With a declination of −34.8, it is the southernmost Messier object. Now go about 3 degrees northwest to M6 (NGC 6405), also known as the Butterfly Cluster. This is also just visible with the unaided eye, and when viewed with a small telescope under good conditions the star pattern can resemble the wings of a butterfly. It is the southernmost object in Charles Messier's famous catalogue.

Trevor n6231 and N6067 nearby in Norma are 2 of the most neglected in the sky; could throw in M55 as well.

Jetstream appears to have moved away from Sydney, time for another look at the Planetary feast and crack Antares tonight!
Cheers Bigjoe
