Eliminating Rectangles in Printed Finder Chart
#1
I have been working with the finder chart for M11. I have my chart settings the way I like them when viewed on the screen (naked eye, finding device, and eyepiece) but when I print the chart there are 3 rectangles that print on and near the M11 image in the eyepiece view.

Questions:

What do the rectangles represent?
How do I get rid of them in the printout?

Thank you,
Jon

Hi Jon,

Hard to say without more to go on. The Finder & Naked Eye views display rectangles that show the extent of the Eyepiece & Finder sections of the chart respectively. Those can be turned on/off in the View property settings. Refer to the HELP.

When I look at M11 using ST4v Pro (4j R16), I don't see any rectangles on the screen. I take it that this only occurs when you print all 3 charts, NE, Finder & EP. Does it also occur if you only print the EP chart?

Can you include a picture of what you're seeing? I think that would help.

Thank you for the quick reply, Phil.
Yes, it also happens when I only print the EP chart (for M11)

Hi Jon,

Check out the chart legend, I think those are dark nebulae. There are quite a few in the region of M11. I didn't notice that the edge of one cut right through M11 on the IA though. You can select the opacity of the nebulae that you want to display(6=darkest, 1=lightest). They're hard to select on the IA, I keep getting faint stars instead of the nebula. I have my chart set to 5 FWIW. Those things are everywhere in the milky way region. Try turning off the star display temporarily to select the nebulae, that helps a lot.

The pictures made all the diference.

Hope this helps,

Phil S.

Thank you, Phil

It seems that I have more control over the printout if I approach it thru the Interactive Atlas, per your suggestion. I am getting what I want now (a better representation of what I am attempting to sketch, in order to check my sketching accuracy)

Hi Jon,

I'm glad that you were able to get a printed chart that works for you.

A couple of things:

1) There are two kinds of objects that can appear as rectangles. One is dark nebulae, as Phil mentioned. You can also just turn them off in the View Controls if they bother you. The other is nebulae (mostly HII regions) without outlines. These are generally very faint wisps of nebulosity for which there is little more than a position cataloged for them.

2) There is a small + at the center of both types that you can pass your cursor over or double-click on to see the object info.

3) The only real difference between the Atlas and eyepiece view has to do with the simulation. The eyepiece view shows things you can see in the scope under the current conditions. Generally that means fewer objects are displayed. In the Atlas you can control the magnitude limits/visibility directly. But in the end they both use the same preferences and view controls so you can turn them off or adjust how they appear in the exactly same way.

The best thing to do is to always use the most appropriate chart for the job, and then customize it to give you what you want. Using the Atlas when you really want an eyepiece simulation would be an unnecessary kludge. The eyepiece simulation shows you what you will see in the eyepiece and no more, which can be useful. In either chart, you can turn off the dark nebulae in the View Controls. Remember you can change everything about the chart, from what is displayed to how each element appears (including colors and line styles) in the Chart Preferences as well.

Technically, I'd call the symbols for the dark nebulae 'diamonds' because they're rotated 45° rather than 'rectangles'. Actually they look more like 'squares' that have been rotated 45°. The sides are almost always equal. Just being pedantic. 

Jon's reference to rectangles was confusing until he provided the screenshot, then I understood what he was referring to.

A picture really is worth 1,000 words  Wink.

I'm glad he was able to get the issue sorted out.
