AR2733 Rounding the Limb at 150mm HA & UV-A | Jan 29th 2019
Posted: Tue Jan 29, 2019 5:08 pm
Heya,
I woke up to pleasantly decent seeing and clear skies this morning. I started imaging AR2733 as it was rounding the limb around 9:30am with the sun at 23 degrees approximately. I imaged both in 656.28nm & 395nm (white light, UV continuum A) to see the difference at this wonderful angle on the limb with a 150mm aperture.
B&W:
Colored:
Equipment:
HA:
Celestron 150mm F8 Refractor
Daystar 150mm ERF
Daystar Quark Chromosphere + PST Etalon
ASI174MM + 0.5x Focal Reducer
WL:
150mm F8 Refractor
3x Barlow (F24)
Baader 2" Blue CCD IR-block filter (ERF)
395nm Filter (UV-A)
ASI174MM
Very best,
