Description

Though my PixInsight Project file is named IC_1871, I am going to have to go with @Gary Imm's expertise and stick with a title of LBN 673 for this part of the Soul Nebula.  If I enter LBN 673 into Aladin, it puts me on the column of dust (or close by) that is just to the right of what is often named the Whirling Dervish.  This column of dust and cloud is the prominent divider wall that separates the two unequally sized bubbles that make up the Soul Nebula.  IC 1871 appears well west of what my image frames.  This region is a dramatic area of star formation, and young hot stars that have eroded the dust into the portion of the local bubble that can be seen here.  As is typical for such action, the erosion is unequal and the result is the formation of columns of dust of various shapes and sizes.  Occasionally, isolated islands of dust can be seen.  One such prominent "island" can be seen on the far right side of this image.  The smallest of these are sometimes called Bok Globules, but I am not sure this one is small enough to be so named.  Bok Globules are thought to typically contain young developing stars.  It may be that they exist because the dust around these stars is gravitationally bound and therefore much more dense and resistant to the erosion such that these regions are the very last to be ripped clear of their shrouds.  The filaments tipping the large columns just to the left of this island are probably more in line with the typical size for a Bok Globule.  These may well become BGs in the near future with a little bit more erosion.  

This image was a struggle to collect data.  I did have much more data collected for this one than I usually use, but the challenge was that this was the last couple of days before the PNW rains started and with that, the forest fire smoke was still a big factor regarding sky conditions.  Of course the rains have removed the smoke, but then it will probably rain for a good 6 months here in Oregon.  I can say there has not been a single clear night during the last two weeks.  But with the smoke, I was not going to pass up at least seeing what I could get with the new scope.  This involved the risk of collecting a bit of smoke haze on the primary mirror.  That coupled with the fogging of the primary twice, caused me concern about the action of water and smoke on the coating.  Smoke particles can release acids upon action with water.  So this week, when I removed the primary mirror cell to install some heaters, I gave the primary a wash.

I am still working on getting backspacing perfected and likely collimation.  Unlike the last image, I do think I am close to getting the collimation zeroed in.  And I was willing to spend at least a few minutes to do that, since it is a pretty simple process.  But knowing that the rain storms were not far west of me, I was not willing to get into a long drawn out affair getting back spacing dialed in.  Simply a trade-off, image or fidgit with gear.  I am not joking about a possible 6 month wait to image again.  So fidgiting will have to wait.  So this image is a bit soft to say the least.  I am actually shocked that I got something out of this...
