Mosaic failed

My b/w webcam has a scratch in the middle of the CCD and thus all the frames are ruined for big mosaic, waste time... X(

Shall use expand image to ease the effort of taking raw AVIs to do mosaic, I expect originally around 30 AVIs can be made to around 20 AVIs with good overlapping.

Time to make a new camera again. :-)

Solar observation

No observation yesterday due to the wedding of my friends and also due to the lazy-ness of myself (hazy sky), AR822 is more more.

Today no beautiful active region but some beautiful prominence.

Did captured 30+ AVIs to mosaic together, see how's it come out.

20051120 AR822 again

this time inside home while Alby was sleeping, again on TG-SP II instead of non-aligned mount since aligned mount is a joy to use indeed... think to kick the LXD55 away.

A sample picture at 0714 (UT).

Consolidated AR822 on 19Nov2005

Solar observation during dancing class of Alby

in a nearby small park, not bad especially in Autumn sky!

Remote solar scope project closure

The focuser was left unmoved during last night, on setting up the whole thing today, it changed drastically so that it's unuseable for remote observation without a remote focuser.

Remote solar scope first light

My remote solar telescope is ready, ready for use, but not ready for remote yet.

Mars observation (4/11)

Around 3:30-4:10am, LXD55 unaligned, Sky90.

Captured 3 clips using color toucam, the middle one has some parts covered by cloud, 5x Powermate alone. Tried to stack 2x on 5x, but the seeing does not support, a blur patch of light, featureless, so didn't capture any of them.

Sky90 was capable enough to deliver that image scale, since nearly no chromatic abberation can be seen.

Finally, used 13mm Nagler + 5x to observe, can see the poor seeing easily. Also, tried to use binoviewer, can reach focus, but can see some strange reflection. I remember that I saw it before... still dunno why. Put the 2x in, and it's even worse. Both can reach focus with the 2x SCT corrector before the diagonal.
