Although I am not skilled in making mosaics (as the following image demonstrates), I realized after imaging vdB 14 and 15 that I could take another LRGB image and fill in the space between the two objects. The additional image was 4 hours LRGB. PixInsight 1.6 and Photoshop were used to stitch the 3 panes together and blend the images. If I knew in advance that I wanted to make a mosaic, I would have rotated the frames in a way that would produce a long, continuous image. I hope you don’t mind the jagged edges, but if it is any comfort, this is typical of many published Hubble Space Telescope mosaic images.
Here is a star map from TheSkyX that matches the above mosaic.
Description
van den Berg vdB 14 is an elliptically-shaped, blue reflection nebula in Camelopardalis near vdB 15 and Shrapless 2-202 emission nebula. It is illuminated by the very bright mag 4.2 supergiant (B9Ia) star shown in the image (HD21291). Both vdB 14 and 15 are embedded in the Cam OB1 group of type O-B3 stars and supergiants.
