Hi all, as some of you already know, I have been playing around with the wee ETX90mm trying to get a reasonable result. Below is an image of the crater Fracastorius using the x2 Barlow given to me by an EAAS member. The image is a stack of 303 frames in Registax with wavelet adjustment etc. There is room for improvement as I only have the scope mounted on a camera tripod and steadiness is a problem if there is any wind. I thought you would like to see the result. To give some scale the small crater on the Mare is 10-miles in diameter and is called Rosse (after the Third Earl of Rosse). Johnmc.

Great image John. There is definitely more detail than your image of the same location without the 2x barlow. Are you using 10fps ? that might help with any wind problems as will prunes ;-) Clear Skies Mark

Excellent image John. You must be very proud of that 90mm ETX. Thanks for the lesson in Lunar geography. I never knew that crater was named after the the Earl of Rosse. My goodness if that crater is 10 miles across then Fracastorius must be around half the size of the crater that resulted from the K/T event 65 Million years ago...thats a monster! I have read that if you divide the crater diameter by 20 then you get an idea of the size of the impactor..pretty cool. Keep them comming John.
