Tomorrow the sun will rise, who knows what the tide could bring?

Over-exposed but still a nice attempt. [smilie=good-job.gif]

Try shooting through ND moon filter. Play with exposure value and ISO settings in your phone camera if possible.

Thank you Sir! Note well taken.

Btw, I tried snapping with a digital camera but not successful. Only smart phone seems to be able to capture. Any idea why?

Thanks.

I am not knighted, you can just call me Gary. :)

I am not an astrophotography/photography expert. Just sharing some of my speculations:

- Digital camera should be able to do eyepiece projection photography too. Easier when mounted on camera adapters mounted on the telescope.
- Phone camera may be easier because one can bring its sensor nearer to the eyepiece projected image compared to the "obstruction" and increase in focusing distance created by the longer lens of a digital camera.
- For hand-holding, it's easier to point a flat phone perpendicular to the eyepiece.

If you used a digital camera, you can set a faster exposure speed and avoid the whiteout. The other way is to put a cardboard with a smaller hole at the front end of the scope to reduce the light.
Depending on the lens design, you may have severe vignetting, so there may be a need to move your camera around until you reach the sweet spot where the image appears. Good luck! :)

Thanks Airconvent for your valuable advice. Will try it out.

Well appreciated. :)
