qastrocam-icon-nb

 

Qastrocam-g2 4.8 was allready able to guide using the QHY5's ST4 port, but I didn't post this small test movie.

 

Sirius is "moved" in the four directions using the QHY5's ST4 port and my EQ5 modification ( Add an ST4 port on the EQ4/EQ5 motor drives ) :

 

 

 

 

Have a nice night !

    After my QHY5 passive cooling modification this summer, I made some noise tests at "high" ambient temperatures (about 20 celsius) :

 

Cooling the QHY5 imager/autoguider (step 1)

 

   I made some more winter tests at low temperatures (about -5 celsius this night).

It performs well for a CMOS !

Just have a look at this really simple focus reminder tweak on my ETX70.

I really like to tweak my Meade ETX70 !

 

Just have a look at my ETX piggyback.

WinRoddier is a very nice application, able to compute most of your telescope defaults with intra and extra focus pictures.

Pretty nice for a low cost achromatic refractor !

 

Have a nice night !

and...many bug fixs !

 

If you need some features on qastrocam-g2, just let me know on sourceforge ;-)

The first feature I added to qastrocam-g2 was the ability to produce text files storing all the autoguiding corrections.

To produce this file, just choose "File" as a dummy telescope. These files are formated like Iris files, and thus can be

processed with PEAS.

 

So have a look to my EQ5's Periodic Error (1st generation, without ballbearing).

Rather regular, isn't it ?

 

Best regards !

This picture from Jupiter, taken in october 2010 is a bit better. Io is there.

I forgot to remove my QHY5's bias current.

 

Have a nice night !

After a long long absence, finally a new post !

 

I previously posted a picture with the two jupiter's cloud bands. We can clearly see the two bands on this picture from july 2009 :

 

jupiter_1_25072009_rgb2.png

 

This new picture shows jupiter with only one band this summer.

The picture is blury because of a very bad sky, with a lot of turbulences...
