Hi All,

I have updated my homepage by putting some Mars images and southern sky
objects. Welcome to take a look at

Also, you can find there a list of what Vixen items I have them in stock now.

Hope you would enjoy my latest images.

Clear skies,

似乎見到大氣色差,如果唔想見到大氣色差,可以獨立重新把RGB channel對位架~

Hi Wah,

Thanks for your opinion.

I don't know how to do the so-called RGB technique, and Canon Lau did a demonstration in HKAS's eGroup on it but I am too stupid to get it.

I had tried to see the RGB channels but found that the 3 frames are not identical in size and in shape, especially for the B channel. So, Canon had re-aligned the 3 channels to eliminate the colour dispersion to a minimum. However, I found from Canon's work, the surface details of the final image became a little softer and more burr.

Therefore, I decide to put my original images in my homepage.
Hope I could meet one night of seeing condition better than 7/10 so that the colour dispersion would not be inherent with my planetary images.

Wah you may reprocess my Mars image with the so-called RGB technique and post here if you would like to do so and to teach me the technique.

Clear skies,

LT
