Hi all,
I am exploring the Sculptor group of galaxies and NGC-253 is the first image I have finished the post-processing. Actually this is my second attempt on this galaxy; the first one was not that good then I decided to wait for a better condition to redo the job.

Hi Dennis,
Thanks for the compliment. No Dannis I haven't guided at all to capture this image, although the Taurus OAG has a nice off-axis port for guiding.
Hi guys,
Thank you all for the feedback. To be able to track for 5 minutes keeping the stars reasonably round all I do is a fine polar alignment using the drift method, that guarantees a star centered in my crosshairs eyepiece for at least 40 minutes under, in my case, a typical 200x power.
It is true that sometimes the alignment takes 5 to 6 hours to complete, but I think it is a worthful time investment. I repeat this routine each 2 months or so.
Hi all,
I was testing my Skywatcher 4" f/10 achromatic refractor piggybacked to the LX-200 and did this image of NGC-253 using the achro.
I am mazed with the quality of the image with such a low end telescope. I did also lots of tests imaging nebulas and other galaxies and all the results were much better than I was expecting.
I tried my 120mm Achro Guidescope last week for imaging. I too was suprised at the quality of modern Achro's!
Big Glass imaging is available to anyone now
(an IR/UV filter helps of course)
