I missed the rules no astrophotography.

Sorry, can a mod move this one for me?


Tried to get a partial of Andromeda with my edge 9.25 / .7 reducer asi294mc pro.

all I got framed was the center core and 1 band. Pretty much a white/green ish glow with a little cloudyness detail.

Any suggestions for smaller fov targets north america this time of year?

Basically a cluster/double/planetary nebula setup but looking for deep galaxies.

http://arpgalaxy.com/arplist.html    Try that. It's " All Galaxies Involved in the Arp Catalog

Sorted in Right Ascension Order" and should occupy a few nights.




Both those are images of the entire Hickson Clusters of Galaxies catalog.



Those are the Lyon Galaxy Groups, favorites of mine.



Here's Alvin Huey's observing guides including some for 8" aperture.


Shoot M101 right next to M31. It's a fine object in a field along with many M31 globular clusters you should be able to catch. But you'll have to research to identify them.


But it all  comes down to research. Do you have a Pocket Sky Atlas? Start there. Google GALAXIES, select IMAGES and see hundreds of thousands in 0.4527 seconds. Pick one and find out if it's suitable for your needs via  https://www.astronom...e/steve.ngc.htm  and   http://leda.univ-lyon1.fr/ 


I've never really understood how folks can run out of objects, especially galaxies.

Google "list of messier objects", pull up the Wiki page and scroll down a bit to the table.

Click on Type (I think) and the table will reorder by the object type, then look at the galaxies.

If right there are not that many but a a few to consider.


If bright enough look up Aarps Peculiar Galaxies.

And it might be worth looking at the Caldwell Catalogue on Wiki also.

On your computer, you can download the free planetarium program http://stellarium.org , set it to your location, and see hundreds of good Deep Sky Objects (DSOs).   smile.gif

First thing you need to do is calculate the Field of View of your imaging rig. To do this, you enter the focal length of your telescope, and the dimensions of your chip. This tells you how large an area of sky you can capture. Then you need to make an aesthetic decision--how do you want to frame your target......Just the target AND a little bit (or a lot) of extra sky around it to frame it? 


Having done this, you know about how large a target you can accommodate. 


To calculate your FOV, you can use a FOV tool found in many places. Google " astro imaging Field of view calculator" and you have a choice of many. many planetarium programs also include one. 


I would suggest Telescopius.com.




Use the tools there to filter where you are, when you want to image, and your FOV...…..And then just look at the sample pics.

Right now you could go for NGC 7331 and or NGC 6946.  You're 9.25 Edge/294MC-Pro would do nicely on those.


You can use this website to see your exact framing of your target with your scope, reducer and camera:
