:: Peçe bulutsusu; NGC6960...

Siyah bir kadifenin üzerine saçılmis binlerce pirlanta taşınin üzerinde uçuşan ipek bir tül.
NGC 6960, diger adı "Veil Nebula" (peçe) binlece yil önce patlamış bir "supernova"dır. Gece yarısından sonra, doğu-güneydoğu göğünde, "Swan" (kuğu) yıldız kümesinin içinde bulunmaktadır. Bize 2500 yılda ulaşmıs olan bu görüntüyü, arkadaşım Clayton Kessler Manchester, Michigan'daki evinin arka bahçesindeki "Seven sisters observatory" diye isimlendirdiği (yedi kiz kardeş gözlem yeri) alanda çekmiştir.
Teknik bilgiler Clay'in kalemiyle aşağıda.

Location: Seven Sisters Observatory - Manchester MI

Equipment: Megrez 90 APO, FFIII, Canon 10D Modified IDAS LPR Filter

Conditions: Excellent! Best night of the year so far

Film: None! DSLR @ ISO 800

Exposure: 3 X 600 seconds with 3 X 600 seconds dark frames

Comments: I took this shot as an experiment. Last year I was shooting 5 minute sub frames. Since I got the IDAS LPR filter I have been able to increase the sub-frame exposure. I tried a 10 minute sub frame to see if I could tease out some of the faint OIII and H-Alpha streaming down from Pickering's Triangular Wisp. Thin series of exposures shows a lot more than I have in my previous shots. The interesting news is the histogram was only at about 25% for each sub frame. I think I can increase the exposure to 15 or 20 minutes on this object. I will be revisiting the veil area all summer taking a good number of relatively long exposures - should be fun!

Conditions: Medium

Film: None! DSLR @ ISO 800

Exposure: 3 X 600 seconds with 3 X 600 seconds dark frames

Comments: Got up at 2:30 to try to gather some photons. I had a few tracking issues and it got too light to shoot by 4:30 so I only had three 10 minute exposures to work with. Not too bad for a "classic" summer shot - WOOHOO - the Milky Way is back!!!!!
