I use the DSS (colour) survey in Stellarium to plan my targets and their framing. I also use the DSS (red) survey to help with NB or Ha imaging, but it is very low resolution and not very sensitive. I had been researching how to add the Northern Sky Narrowband Survey to Stellarium, when I discovered a post on, I think, a Facebook page, that they were already built into Stellarium.
So if you didn’t know they are part of the Stellarium Sky Surveys, or don’t know much about using the Sky Surveys in Stellarium, this is how you access and make use of the survey’s.
1. To begin, you need to have the HIPS button active on the Main Toolbar:

2. If the HIPS button is not present, then go to Configuration, Extras tab and make sure HIPS is checked. Then close the Configuration dialogue.

3. To see the survey’s, right-click on the HIPS button on the toolbar. This will bring up the Sky Surveys dialogue box:

4. Click in the “Filter” search box.
5. Type NSNS. This will filter the surveys to just the Northern Sky Narrowband Survey’s.
The ones of interest are NSNS DR0.2 Ha (8-bit), NSNS DR0.2 [OIII] (8-bit) and NSNS DR0.2 [SII] (8-bit). Though you can test the other survey’s as well.
6. Now select the NSNS DR0.2 Ha (8-bit) survey and close the dialogue box. The survey will be displayed showing all the Ha detail.
This makes it very easy to see the targets you are interested in and to frame them accurately. Or to see which targets are abundant in Ha, Oiii or Sii.
Here is an example of a target I was planning on imaging with my Samyang 135mm lens: Sh2-216 and Sh2-221. Below are the DSS colour and DSS red images of the target:

You can see Sh2-216 is visible, but you cannot see Sh2-221 or anything else that might be in the frame.
Now, here is the same area with the NSNS DR0.2 Ha (8-bit) survey activated, followed by the Oiii survey and Sii survey:

📷 Stellarium - NSNS DR0.2 Sii 8 bit.jpg
As you can see, all the Sharpless objects in the frame are visible so you can now plan your framing for the imaging session very easily.
I hope this little tutorial will be of use to somebody.
