Lunar Eclipse 2018 July 28


2nd Lunar eclipse of the year 2018.  This time I went to the rooftop garden accessible from my block.  The sky was covered with clouds around 1 am and near totality as well as the last hour of the eclipse. P900 is good when there is enough lighting. 




Before the onset of eclipse 28/7/2018 01:42 - the moon spotted in  straw color


Shadow coming on 9 - 10 o'clock position

Shadow created a crescent moon look
Expose for the earthshine area





Blood moon

One hour plus 20 minutes of  full eclipse 
Wider angle view shows Mars and the blood red moon in comparison



The white cap formation - about this time waves of clouds came and I ended my monitoring

Sprite Lightning and A meteor in Crux

  With Tiangung 1 reentries on April fool day in my mind.... last night i went to Space Track and download the TLE ...

  SPRITE Woke up and find a cloudy sky outside. I glanced at the wall clock ... thinking I should shut the system down instead of the scheduled 7am automatically.   Luckily I didn't stop the gazing ccd /lens much earlier.

    As I strolled through the captured frames through a long list of cloud-filled sky. Then this sprite peak-hold image jumped out at me. There was another clip where only the top 'tentacle' was seen. I bet a group of sprites was exhibiting themselves nearby.  I want a closer look - the 25mm Avenir f 0.95 manual iris lens and Watec 902HUltimage.  The time stamp says 6:32

Sprite caught in 25mm f0.95 lens. Ufocature sw



Partial Sprite seen with a few tentacles



Another Deja Vu  -  As I trained the lens to centre on the Compact southern cross Crux i had the intention of why not getting a meteor flash by the Cross.  ( did this thinking many years ago and i got it too).  Mum took a month holiday so i stick out the lens from this unit.

If they come you will be captured.  A proven bw reliable set up but migrating to  a color mirror-less camera and high video rate system will start as soon as i got some decent sky and meteor streams picking up after April



More for aesthetic than anything else.  Crux or the Southern Cross giving you an idea of the lens FOV too

Humanity Star March 09 2018 flashes images

Humanity Star March 09 2018 Passages through False Cross Vela




    Using Virtual dub to step through the individual flashes.

    First, a combination plot showing the series of flashes of varying brightness as detected by Ufocapture software. I hit the rec button when the time is coming and hit again to stop recording. The peak hold images through the exposure will flag the Humanity Star flashes.

    Humanity star travel upwards from bottom to top within the red lined box


    The followings are individual frames seen from using a VirtualDub slider to step through the individual flash






Humanity Star brighter than delta Vela
HS is ~ as bright than delta vela ( mg 1.95 )

Humanity Star - Flashes by Canopus March 06 2018

Humanity Star 




From heavens-above for my location - Humanity Star ( HS) Mag +5.1 passing close to easily recognisable Canopus on March 06 2018 ~20:24 before entering earth's shadow.  Canopus is visible through my sitting room window.

But there are clouds
Clouds were there and luckily sky cleared and the mag 6 + stars visible

Using Sonotaco UFOcaptureHd software, I hit the button around 20:24:13 and let it records 3 minutes. The resulting peakhold images revealed clearly detected flashing 'dots' per the heavens-above plot.

I tried replay the avi file and managed to detect a flash at 20:24:41. Then after a few attempts managed 2+1 additional flashes.  I also tried stacking the avi using Registax which had no benefit for very short tiny flashes.  THe canon setup didnt see anything as i started the remote release too late.

Canon G5x and Watec 902h2/ Avenir 25mm f0.95

G5X gave pretty good stellar magnitude too after histogram stretching
