Okay, after the spammer bs. The revised Basic PST imaging slideshow - http://members.csolutions.net/fisherka/astronote/astrophoto/setups/PSTDiskSe...

To image prominences with a DSLR, it appears you use the counterintuitive technique of intentionally overexposing the disk - since the prominences are relatively fainter than the disk. - Kurt
