Little Rosette Nebula (the period in the Question Mark Nebula

Last year at this time I took pics of the Question Mark Nebula. This year I took pics of the period in the Question Mark and the period is called the Little Rosette Nebula (SH2-170) and it certainly looks much like it’s much larger cousin the Rosette Nebula. I can’t find reliable information on the size of the Little Rosette but it took maybe a half to a third of the frame using my 585MC. The Rosette Nebula would be 2 to 2.5 times wider than the frame of the 585MC. So the little one is much littler! My guess would be the little one is 10-20% of the size of the big cousin. It is also interesting too that the top of the question mark is located in Cepheus and the period in Cassiopeia.
