31-1-2010 Solar Image

Yesterday got a call from the dealer. He said that my LS35T problem is arisen from the objective, not the etalon. The objective got serious astigmatism. Gosh! When I hear this I was scared because my LS35T is a special edition and the objective was made by Carl Zeiss which means there would be no replacement! The current LS35T uses non-Carl Zeiss objective. I am lucky enough that the last LS35T, there are totally 4 Carl Zeiss editions in Asia, is not sold yet! I can have replacement right the way! Hooray! I will take it home this week and fully utilize it as my F.7 class will be finished.
After more than one month of bad weather. Today is a sunny day. I used the dealer’s courtesy LS35T to shot the sun. Although there is no sunspot, I got two big prominences! Since the diameter of the sun is about 110 times than that of the Earth, the biggest prominence is about 3 times the size of the Earth!

LS35T Sent for Repair

After watching the dealer’s Ha angular eclipse photos, I smell something fishy about my LS35T. I watched LS60T, LS70F and LS100T before in David’s solar party. As there were many big solar scopes, I didn’t draw much attention to the LS35T. After I bought my LS35T, I found the detail of the sun surface is not shown clearly. Originally I thought that was normal, LS35T cannot be compared with those big scopes. As u can see in my 1st Ha photo which was shoot by my LS35T. It seemed that it was abnormal. So I found David, who is an experience sun-gazer. He confirmed that my LS35T needed to be repaired. So I sent it back to the dealer for repair. The scope needed to be sent back to US. The dealer is so kind that he lent me his own LS35T. During the waiting, I can still do solar observations! Great! When I went to David, he let me tried his prestigious unobstructed LS70F and APM 80/480. Visually the surface detail shown was wow! The photo was taken by this setup. The photo was not particular good because of my bad skill!

1st Solar Ha Image

This is my 1st Solar Ha Image I took on 12th Jan 2010. This was certainly a bad image. Although it showed a sunspot, even a white light filter can do it. I have used several times my LS35T for visual observation. I knew it shows less detail compared with LS60T, LS75F or LS100T, but I didn’t know it is abnormal or not. Today I confirmed my LS75T is abnormal after I consulted my friend who is experienced in solar observation. Good grief! I need to send it back to the dealer. Hope to get it fixed quickly!
