Lower middle 1994 PS10 Mag 20

*The Gif compression degraded the quality.*

wow, and i mean wow! that is fantastic. I had only ever seen animations from David Higgins and Dennis Simmons of faint stuff like that but to bag two in one go -amazing

[iceman (Mike)]

That's excellent, Theo! Took me a while to find them but there they are!

Very good result, great achievement.

that's awesome. I wish I had a telescope even close to being able to do that.

btw, where is that in the sky? got any coordinates?

Hi Theodog,

Excellent, excellent work! At least once a week nowadays I seem to pause, shake my head and say "I never thought I see an amateur do that".

And you've done it again, congrats.

Best,

Amazing. How long between the frames to show the movement?

what a cracker Jeff

[Matty P (Matt)]

Wow! Amazing work Jeff.

They sure are faint!

[theodog (Jeff)]

Thanks all.
Imaging asteroids is not hard. Use a star map that plots the position and magnitude of the asteroids, I look for "close encounters". Use the program to plot a trail of positions OR plot the positions 10 minutes later, this will show movement. Simply image 2 or more times and align the stars. Blink software helps.

My standard set up is 4x10min-L with 6sec between, then 1 dark.
Process all with dark, align and blink (0.2sec/image).
Simply combining as Sum of images usually displays a "little sausage" of asteroid.

Get out there and give it a go. Its a good project for the light moon.
