There is something strange in the catalog of Lynd Dark Nebulae and GUIDE.
Recently I took images of LDN 2, according to my Lynd Nebulae Catalog ( the original one published by Lynd). After made a registration of my picture to get the coordinated of the nebulae, I got 18h 07m 14,9s -31° 29' 31,6''. Putting those value in GUIDE, an I arrive dot LDB 4.
More confusing, Guide report the objet as LDN 4 (873). I try to get access to More information with the LND catalog use by GUIDE, but I seems that we don't have access to it.
Why there is a discrepancy between my catalog and the one use by GUIDE ?
What is the meaning of (873) reported by GUIDE for LDN 4 ?
Why are we unable to get acces to the catalog of LDN within GUIDE ?
What is the source of LDN catalogue used by GUIDE ?
