Yes, it is possible to get a DSO image from a Dobsonian scope without an equatorial platform for tracking,  but I wouldn’t want to have to do it too many times!   lol.

Keeping the object in the field of view is tough.   Dealing with hundreds of images and only 25% are usable is a pain.   Plus, you have to manually pick and sort them, which is even worse.  And after all that effort, you get such meager results like the above?   Yeah, like I already said… I wouldn’t want to do this more than I have to.   🙂

Rupes Recta – The Straight Wall

Rupes Recta - The Straight Wall on the Moon.  3 frames stacked in IRIS, wavelets and unsharp masking.

I’ve always loved this particular feature on the moon.   I want to have a night of great seeing and image this with the most powerful stuff I have.  The six inch shows it well enough, but my 8 inch scope at f/20 or 4000mm f.l. would really be what’s needed.

The Moon – Plato, Archimedes and Copernicus

Famous craters Plato, Archimedes and Copernicus on the moon.
Famous craters Plato, Archimedes and Copernicus on the moon.

This area of the moon includes Mare Imbrium and the three main craters Plato, at the top right, Archimedes, in the lower center and Copernicus on the left below center .  Also visible, coming out of the shadows from the right, is a section of the Apennines Mountains.  Near the end of the Apennines is Eratosthenes, a crater about half the size of Copernicus that has a prominent central peak.

Another moon mosaic for the month of October.  Since the weather was so clear on this early October morning, I decided to do some more planetary-style imaging with my new planetary/guider cam.   Decent seeing and as already mentioned, very transparent skies.   It was a little chilly, but not too bad when wearing two coats.    🙂
