Moon from Seattle

[roygoh]

Since it is Mid Autumn Festival today, I decided to join in the moon craze. These are fresh out of the oven, taken 2 hours ago. Processing in PS includes:

- Levels and curves
- Despeckle
- USM
- Resize

The contrast is exagerated to bring out the surface detials.

Setup:
- CP995 camera
- William Optics DCL-28 (eyepiece adapter) + moon filter
- Meade ETX90 RA telescope
- Benbo Trekker tripod

Thanks for viewing!

I am speechless.

Hey, your moon is facing the opposite side as mine (Seattle vs. Singapore). In my shots, the white star formation (whatever) is on the lower right side.

so detailed.. even got craters[i think it is called that?!]

[destiny_star]

pardon me for my ignorant.. coz i'm new to it.. but did u sort of attached a camera onto ur telescope and hence produce the photo?

i'm not very sure of ur setup though..

nonetheless.. it's very marvellously done..

The views of the moon in Seattle is rotated clockwise with respect to the view in Singapore.

The white star formation you referred to is the crater Tycho. The rays radiating from the crater are formed by debris blasted out of the moon's surface when the crater was created by an impacting meteor in the early years of the moon. Tycho is 85 km wide and is the youngest crater on the near side (earth facing side) of the moon.

Thanks!

The craters can be easily seen with a 10X binoculars. The surface details are more pronounce near the terminator (transition line bright and dark side) because of the shadow cast by the oblique sun light.

Please refer to my earlier posts:

To understand my setup, please go to www.scopetronix.com, on the left navigation bar, look under ">Eyepieces" and then click on the link to ">Scopetronix eyepieces". Scroll down about 1/3 to 1/2 the page and you will see the eyepiece-telescope adaptoer specifically designed for the Coolpix digicams. You will also see a picture of the camera attached to the Meade ETX 90 telescope, which happens to be the same telescope I am using.

The eyepiece-telescope adapter I am using is made by William optics, which is similar to the Scopetronix design. I think the scopetronix design has better performance as they have wider angle of view.

Hope this helps.

Thanks!

I don't have a telescope (maybe sometime in the future I'll get one). With 400mm and 6MP, pretty decent and detailed moon pictures can be taken, especially if your intent is to use on computer screen. At 1200mm (400mm + 2x teleconvertor + 1.5x crop factor), and shooting at 12MP (S2pro's RAW file), the resulting moon is about 1400 pixels high.

Roygoh, thanks for the clarification on the moon facing. I have thought that the moon looks the same everywhere in the northern hemisphere, hmmm... I need to revise my astronomy and physics!

Tycho would probably be the name of the early telescope astronomer Tycho Brahe.

I have seen members here have posted very decent moon shots using telephoto SLR lenses without telescopes.

As for the orientation of the moon with respect to the zenith at any location on earth, I believe it should be related to the longitude of the location.

As for the naming of the crater Tycho, I believe you are right that it is named after the astronomer Tycho Brahe. By the way, I believe Tycho died a few years before Galileo constructed his first telescope, so he is not a telescope astronomer (http://www.physics.northwestern.edu/...103/brahe.html).

Thanks!

Your moon photo is good.

...unless if you are not located on Earth...such as Jupiter...

Unless we are standing on our own little piece of real estate on the moon. Interesting that land on the moon can be bought! Who owns it in the first place...

hahaha
