Hi all,

 

Is there a software package that I can set my scope specifics into (mirror size, f/ratio, eyepiece power, etc) and then print out maps that show only items to a specific magnitude in one eyepiece FOV?

 

For instance, I have a 16" dob. I am hunting faint fuzzies and find a planetary nebula. I would like to have a map that just shows what will be in my FOV at a 17mm eyepiece down to 12th - 13th magnitude. I would make a map for each planned object ahead of time.

 

As is, my little field atlas shows far too few stars for my current scope, and I am having difficulty getting to some objects.

 

Thanks!

The SKYX can do this.

SkySafari and Stellarium can do this for you too.  I use SkySafari all the time while in front of my eyepieces.

Any planetarium program at all will print a finder field.

 

As a sample, attached is a 30' field around the planetary Abell 12 in Cartes du Ciel; V-mags from

the UCAC4 are restricted to a limit of mag 13 (color) and mag 13.5 (B & W).

 

IMHO, the quality of prints from CdC is very poor; this amateur figured out how to get high-quality

prints from CdC

but hasn't shared the method.

 

Sample snapshots of the same field from other programs could help the OP decide which program

is the best one to print finder charts.

Thanks folks. I tried Stellarium but I need more practice with it. Will look into the other suggestions as well.

SkyTools is probably the best for this, but it's not free. IMO it's well worth it though. It also excels at making custom observing lists and for keeping your logs in order.

The view below is a screen shot centered on Abell 12, with stars showing to Mag 13, which should be comparable to Catalogman's example in post #4. although they are not at the same scale.  This is from SkySafari, and the circles show the FOV for my AT115EDT with 24mm, 14mm, and 4.7mm eyepieces.

For ease of use and printing Megastar.
