help,please. just picked up my new dsi pro for etx 125. i cannot get a clear shot of the moon (to bright), and when trying land pics during the day, you can see the internal mirror from the scope. land targets focus o.k.,but image of mirror in center of screen(bright spot). moon cannot be focused.,brightness sends contrast crazy. any help is appreciated thanks!

for lunar imaging you need very short exposures.
.025 approx

Can you tell us the telescope you are using for imaging and any other detail would also help.

thanks mark and  dave, im using a meade etx 125 pe. the imager is a meade dsi pro,and i am using a moon filter.,do i use a 2x barlow? when trying to focus all i get on the laptop screen is a strong white image,then its as the camera gets overoaded with brightness. i am focusing on terestrial targets pretty well though. this only seems to happen when trying the moon. i have also noticed that on the image screen, the camera is also picking up the mirror image from the scope(as if you pulled the eypiece and looked into the scope) on either terestrial or sky. thanks again guys!

I wonder if the DSI is too sensitive for the Moon?

I use an ordinary digital camera and generally get OK results:

philip, that is what i had been thinking. went out and bought a lpi imager yesterday. cant use it though cause my laptop has vista . keep everyone posted !

Read 1 of the back posts on getting the LPI to work with vista.
I believe its pinned on the lpi catagory.

Thanks, Mark. I was going to suggest the same. However, I still think there's lots of scope (if you pardon the pun!) for using ordinary digital cameras. I'm getting a 12 megapixel camera for my birthday tomorrow and hope to post some even better stuff than before.

The biggest problem with LPIs, DSIs and webcams is that its difficult to get the whole lunar disc in, so you end up "stitcthing" photographs together.

thanks guys,ill give it a shot. why do i get a lot of "static" when either my lpi or dsi is connected. mark if you are refering to trying to force the drive and switch compatability, i have tried that and it still will not load any drivers. any help wth that will be greatly appreciated as i am pulling my hair out. thanks again

t seems when you instal the imager on vista, Vista renames the camera.
That is why Vista wont recognize the LPI.
Some one has done a lot of research on it and has come up with a detailed fix.

It seems that no matter what Meade does Vista re names the imager for us.

Here is the link for a fix.
Do this at your own risk if you dont know how to edit your registry!!!!!!
Meade or Myself do not take any responsibilitys for this fix.

mark, i tried the fix and it appears to work. as soon as the weather clears i will try it on the moon. i was targeting and photographing some street lamps last night and it worked well. i just had to get used to the exposure and others settings. as for my static problem, it is not happing on my new laptop. i would like to thank everyone for helping once again. i will post pics once the weather clears.
