Greetings All,
It has been quite a while since I have posted anything or participated in the forum discussion. Seems I have been working way too much and the weather has had a bad stretch in my area (which normally has clear skies at this time). I hope both work and the weather changes....

Here is an image of LDN 1622 which I managed in February this year. It is a dim object (I guess I should expect a dark nebula to be dim). Its in Orion just outside the bright section of Barnard's Loop. Image and exposure / processing details are here:

That's a really cool image Jim! I've spent the last several minutes trying to find this object in my resources. Based upon the coordinates you gave, I can pick out the 5 or 6 brightest stars of your image in my copy of Uranometria 2000, but the dark nebula must have been deemed too "insignificant" to include. It sure is pretty!

Really nice work Jim! These dark nebula are really tricky to process, and you did it nicely.
Cheers,
Tyler
