LtE in CMO #272


. . . . . . . . . . Dear Sirs,


My name is Paolo Lazzarotti and I like to image solar system planets from my location placed in a small city in Tuscany region, Italy.

The image you can find attached it's the first one about 2003 Mars opposition. If you feel my work might be useful for your purpose, I'll be happy to share my works with you!

. . . . . . . . . .Dear Masatsugu,


Nice to hear this from you! Yes, I'll care of sending you all my work. Yes, as you noticed through my website I like very much to capture frame of Nature.

I'll go to make RGB imagery from next image every time seeing will be not so bad!

Very nice result, Chris!  Talking with Italian Mars coordinator Paolo Tanga (he's working in Nice Observatory), an IR-cut filter would be welcome with color CCD devices like webcams. Can you try to use one? You'd better balance red and blue channels imagery for a real appearance of the planet. Furthermore, can you better explain to me what's RRGB image?



. . . . . . . . . .Here attached my latest Mars image through R channel only. Unfortunately G and B final frame of tricolor image are suffering of a "strange misalignment" effect, such as my software wouldn't be able to align them properly. I checked more and more times but in vain; I suppose this is due to the atmospheric turbulence because in R frame this is not visible, in the G channel does begin to be noticeable and in the B one is terrible!

Any suggestion?

. . . . . . . . . .Here attached my latest Mars image in R channel with fair/good seeing and thiny clouds crossing the planet. You can also find my G and B channels captured at the same time with same conditions. Is there someone who can explain me what's due the vertical splitting affecting these 2 channels? All attempts of mine to capture pictures through G and B filters give the same result so far. Thank you very much for your eventual help.

. . . . . . . . . .Here my latest Mars image taken at 1500 m. altitude with excellent transparency and poor to good seeing. For the first time I followed all the night the Red noticing a large cloud (B channel) at sunset limb to disappear behind the disc. Seeing was variable and so I wasn't able to get a following RGB sequence for color image. Hope this helps any way.
