Hi folks:
reposting

Hi folks:

The weather acting up for a long long time. Decided last minute to
try my luck on my first ORI watch ..

Here is a link to a quickie page showing one of the negative
magnitude Orion fireball captured this morning. Other Orions are dim (
+2, +3) but show up well on tape. They are swift >66 Km/s. Bit
difficult for me to tell them apart from EGE ( ZHR~2) vs 20 for Orion..

ORI - fireball http://www.ykchia.com/orionids_03.htm

For both Oct 18 and Oct 19 local time 4 am onwards - Orionids -
particles remnant of Halley Comet are showing up steadily in the tape
recording using watec-902H /25mm lens..

Managed to bag x4 Ori on Oct 18(1 hr) and x8 Ori Oct 19 predawn
sky. Visually ( mag 2-3) the sky was hopeless but via infra sensitive
ccd (LM>+7) it is another matter. ( narrow field unfortunately)

Orionids peak on 23* 4am - on weekday unfortnately.

Thanks doc! Really interesting..Just wondering ya can do IR imaging on CCD? :?:

wrapping up Orionids 10/22

Hi folks:

Third attempts on ORIONIDS this morning with similar video set up from 4am-6am.

Sky was not good but still see down to mag 5+ in video. The only exciting meteor was another ORI fireball that zipped pass Orion and disappeared outside the FOV. No train was observed and the velocity was so fast that the 1/25 second frame speed did not produce a meteor head after applying a video deinteraced treatement - instead the meteor was frozen as a 'bacteria-like' or 'rod-like' blob with a tiny tail. ( Will post image later.) The angular velocity ( degree/s) and the path length did not look to me like any Oris seen on Oct 18,19.

The activity seems to fizzle out as I count not more than 2 or 3 un-interesting meteors. Observed a strange slow moving arrow-like fat 'cluster' (birds formations or what??) will recheck tape over the weekend.

Scores of Orinids report started to pour in from North America observers.. many reported fireball Orids with persistent train.. so the fireball phenomena is real !

Hi KCY:

What i mean is ccd (most ccd) is sensitive to infra region of the spectrum so it can detect star light better than our retina response. (translate to deeper LM reached). Also another example is you noramlly can not detect the IR - remote control's beam but if you use the watec ccd/lens the infra beam is readily detected....

Watec 902H helps a lot - it can see through thin clouds and reveals stars / meteors/Sats easily. I have mintron too but like the real time sensitivity of watec 902H and fast video lens combination better for meteors.
