My first observation of an Ellerman Bomb

 


When looking at my H-Alpha timelapse I noticed a bright white light popping up beside a filament. The time between between the two pictures is 10 minutes. I found out that this phenomen is known as a Ellerman Bomb or a micro solarflare.
This is the first time I observed and imaged this phenomen.

Sun H-alpha June 4


Full disk H-Alpha image of the Sun this afternoon.

Setting : SolarMaxIII 70/400 f/5.7 DS BF15 with ASI290MM and reducer 0.5x
Software  : SharpCap Pro, AS3!, IMPPG, CS4

Seeing tool  : 20.000 frames captured, only 1000 saved for processing of which 50 best frames are used for stacking.

Comet C/2017 K2(PanSTARRS)



The next months it will be possible to observe (and image) a special comet. Comet C/2017 K2 (PanSTARRS) is estimated to reach magnitudes around 8. So not visible with the naked eye but as it's the first and only passage near the Sun anything can happen. The comet is an Oort Cloud Comet and after it's passage it will leave our solarsystem.

Some special moments :
- June 18-23 near object IC4665 Summer Beehive Open Star Cluster
- July 14 closest distance 270 million km to Earth
- July 14-18 near object M10 Globular Star Cluster
- August 2-5 near object M107 Globular Star Cluster

Sun May28 - H-Alpha Full Disk



Some more trial and error using my focal reducer 0.5x with SolarMaxIII and ASI290MM. I noticed that the flats taken from yesterday are popping up when imaging in SharpCap Pro. I renewed the flat and after restarting SharpCap Pro the full disk image was much better. I could image on 80fps with an exposure time between 0.3 and 0.5ms - gain set on 100.

Setting: SolarMaxIII 70/400 f/5.7 DS BF15 and ASI290MM
Software: SharpCap Pro, AS3!, IMPPG, CS4.
Adding Color CS4 : RGB1,8 - R 1,33- G 0,44 - B 0,2

Full Sundisk H-Alpha



Using my ASI290MM on SolarMaxIII 70/400 f/5.7 the Sundisk could not be 100% captured. Therefor I bought a 2" focalreducer x0.5. 
The first result is promising.

Setting : SolarMaxIII 70/400 f/5.7 DS BF15with ASI290MM (and focalreducer 0.5x)
