104 Spotless Days & Limb Darkening

The picture of the Sun today shows again a Sun without any sunspots. So far this year, 104 spotless days are registrated; in 2017, it took a full year for those 104 spotless days. This means we are heading towards a solar minimum.

The picture also shows the Sun is more bright at the center and darker towards the edges. This phenomena is called Limb Darkening - which I will explain later (when I have time :)

Sun with SolarMax III and ASI224MC

The Sun today around UT08h45 observed with SolarMax III (f/5.7 70/400 DS BF15) and ASI224MC for 60s. This time true color stacking providing a red color instead of BGGR blue color (see my blog here). 

The Sun with SolarMax3 and ASI224MC

The Sun this morning; observation with SolarMax 3 (f/5.7 70/400; BS en BF15) and ASI224MC. Capturesoftware SharpCap for 60s and stacking using AutoStakkert in BGGR. This results in a (false) blue color, but the provides a nive and higher contrast. Located centrally on the Sun's disk you can see a white bright active region, but without sunspots. Also different prominences can be see at the limb of the Sun.

Nightscape Milky Way and Mars

Some nightscapes from my backyard. One with our own galaxy or Milky Way and one with part of the Milky Way and Mars.

Mars TAL200K ASI224MC - Record of 58.000 frames

Last night I was able to take some more pictures of Mars. Mars is currently very bright and getting bigger every night. Details are now visile on Mars's disk. A total of 58.000 frames were made due to the fact I was able to lower the capture area and the fact the scope was well positioned.

Pictures made with capture software SharpCap and stacking with AutoStakkert. Final editing by CS4.
