Jupiter May 21st night ( 木星の撮影 ）

It may be famous for Google Blog to correct Statistical data. That I found yesterday some persons from USA visited to my Blog.

So I decided to add English explanation , to share my approach of Astronomical Picture development. 

Today's Topics is Jupiter.

Here is my data 

FireCapture v2.5 beta :-> Already Beta version is moved to formal.(Both way)

------------------------------------

Scope : Takahashi Mewlon-180  x2 barrow 

EQ: Takahashi EM10

PC: Panasonic CF-N10  USB3.0 connection

Camera=ZWO ASI290MC

Filter=G

CMI=136.3° CMII=261.8° CMIII=32.3°  (during mid of capture)

FocalLength=6550mm
Date=210517

Start(UT)=130918.557

Mid(UT)=131003.556

End(UT)=131048.556

Duration=89.999s

Date_format=ddMMyy

Time_format=HHmmss

LT=UT +9h

Frames captured=3140

File type=AVI

Extended AVI mode=true

ROI=600x600

FPS (avg.)=34

Shutter=28.67ms

Gain=280

WRed=47

USBTraffic=84

Brightness=73

Gamma=27

HighSpeed=on

Histogramm=67%

Limit=90 Seconds

Sensor temperature=30.0 °C

Most Setting is learned from many HP or Blog topics, some key items to pay

attention,

1) Shutter to be faster :around 10msec

2) Histogram over 50%

3) Expose duration 60-90 sec for Jupiter (since rotation fast)

4) Wait for stable night day,,,

5) I add ASi Camera Filter selection under Fire Capture as Green , sometime CH4

    You can reach spectrum chart of ZWO ASi290Mc Data sheet page 

This object is net easy to get fine and nice looking .

Cause JPN is strong air flow on the sky which making bad seeing  and as far as I know Philippine is best location to take Planets pict by Scope for example . What I can do in JPN is to wait for stable night....
Continue to discuss my Image Development process about Stacking and wavelet .
