I think the phrase you need right now is..

"OK Honey, I'll get right on it!"

I am still processing the backlog of data from early October. Amazing how quick I forget the use of Registax and Photoshop

I did this small mosaic of my favorite Plato region as another warm up:

And also this weird idea I had: how big is Jupiter compared to Plato? Pretty close it turns out. Overlaid Jupiter on the Moon after using same optical train and camera:

I presume that you mean "apparent diameter" Alex

"Overlaid Jupiter on the Moon after using same optical train and camera:"

Wow, this really showed how far away Jupiter is considering how much larger it is compared to our moon:

John

Follow this link and then just do it.

Earth as a peppercorn

I have done it three times, the first time with my eldest son. I thought I understood it. Only by doing it, did I truly understand what it meant.

I've done it with my father, who said he got it, but when he did it, he finally understood it.

I've done with some coworkers, who said they got it, but after they did it, they got it.

I tend to use traffic lights at intersections as the sun. You get to see them from over half a mile away, whereas as a ball or something else will just "disappear ". The other stuff is expendable, I rarely go back for it.

My coworkers get annoyed when I keep saying we have travelled to the moon, 2.5 inches, we want to go to Mars, 14 yards, the next nearest sun, 4200 miles. All on the same scale. And we think we are important.

Look at the relative size of the stars we look at. We are tiny

Have fun

Nice capture Deck.

Aquila and Delphinus show up very well.

As for the streak of light, could it be an aircraft light etc? passing through the F.O.V during the exposure?.

Regards. Peter.

Hi Deck:

I'd say it's either a satellite or airplane.

If you know the rough date and time, you can use Calsky Calsky link to identify what it was. It's not 100% foolproof but I have found it useful to identify around 90% of fast moving objects. If it was a plane then it will not help.

Have fun

T'm somewhat pleased with this image taken last night having now changed, (thanks to Haytor's advice), to the use of Stark Labs "Craterlet" software and also the help given by a few of the experts over on the "Solar System and Lunar Imaging" forum.

Scope: Nexstar 8i OTA on a HEQ5 Pro GEM .
Camera: Philips SPC 900 NC + X3 Barlow
2000 frames AVI @ 10 FPS. Gain at aprrox.
75%. Zero % Gamma setting.

Best regards,
Tel

And another shot made some 15-20 minutes later. I was surprised by how much the planet had rotated in such a short period of time. The right hand barge on the first image has virtually disappeared !

Incidentally, I forgot to add that both AVIs were processed in Registax 6 and in P/Shop CS2.

Thank you for looking.

Best regards,
Tel

Two more fine images Tel. Many thanks for posting.

It's good to see through your images, what I was looking at myself last night. Around 21.15 to 21.45 if memory serves.

The barges do give a good indication of how quickly surface features move.


Regards. Peter.

Excellent images, Tel! About how many frames did you stack?
