Moon Halo


In the evening of March 14, an 360° halo around the Moon could be observed. First the halo was visible with some faint clouds but later that evening the sky was covered with a plain faint fog.

Moon 5% Illuminated

Moon on March 4th, only 5% illuminated.



The effect of guiding calibration

Before guiding (PHD2) gets started it will be doing a calibration session. Pulses are giving to move the star out of center so the software knows what to do in case the star is not following anymore..
The effect of this calibration session was imaged and is seen below. Picture in H-Alpha with 180s exposure time.



Horsehead and Flame Nebula in H-Alpha ASI2600MC


The Horsehead Nebula (IC434 or Barnard 33) is located in constellation Orion and about 1375 light years away from Earth. The Flame Nebula (NGC2024) is also located in constellation Orion and about 1350 light years away from Earth.

The pictures are taken using a H-Alpha filter.

Guiding : ZWO Guidescope 30/120 with ASI224MC
Lights : 10x300s, 2x600s (total exposure 70min)
Software : N.I.N.A., Stellarium, PDD2, APP, CS4, DeNoise AI.

M46 M47 and NGC2438

Open star clusters M46 (NGC2437) with Planetary Nebula NGC2438 and M47 (NGC2422/2478) are located in constellation Puppis.

Setting : ASI2600MC with TLAPO80/480 f/6; ZWO Guidescope 30/120 and ASI224MC
Lights : 2x90s 5x300s
Software: N.I.N.A, Stellarium, PHD2, APP, CS4







Orion M42 - OIII and ASI2600MC

Past weekend I took the time to optimize my PHD2 guiding skills. The build-in "Guiding Assistance" was used and the camera exposure time was increased from 1s to 2s. The guide pulses in EQMOD are increased from 0.5 to 0.9.
I made sure the 2" flattener was set at exactly 105mm till the + 17mm ASI2600MC chip. 

Setting scope : ASI2600MC and TLAPO80/480 f/6
Guiding : ZWO Guiding scope 30/120 and ASI224MC
Software : N.I.N.A, Stellarium, PHD2, APP, CS4, DeNoise AI
Lights : 10x180s 5x300s
Light 2" OIII filter: 8x300s 3x600s
