I can't see any features in my image.

• Try zooming out to see your entire image. You may be zoomed in on a small patch.
• Use the Digital development or Levels and Power Stretch tools to bring out the features in your image.
• You can also try changing the scale of your image. Go to Image -> Scale Intensity -> select "Log" and then hit "Done". This is particularly helpful for images of nebulae.
• You might need a longer exposure using i-Telescope.

• Make sure each of your filters (and filter stacks) has been aligned using Align and Combine.

• When using the Align and Combine tool for alignment, make sure that you select "Save each file" in the "Output mode" option. This should give you three files that each start with "align_".

• Try using the Adjust Color Background tool.

• The files you download from itelescope.net are usually compressed .zip files. You will need to extract the FITS files from the compressed folder in order to open them in Nebulosity. To do this, use your file explorer to navigate to the folder where you have saved your itelescope.net files. Double-click on the .zip file. Select the file inside and click "Extract". This will move the FITS file into the folder you have specified. You should now be able to open it with Nebulosity.
