Beautiful images. I am impressed with the proms on your FD, are you now using the Lunt module with the front ERF replaced by a Baader blue filter as you noted in a previous post? I ask as I am having problems with reflections with my Lunt module when I increase gain to image CaK proms.
Thanks for your comments. I add the following image of this afternoon

@John - I used of the original BF of the module (you can note the uneven brightness around the disc due to those damned tilted filters) while for the prom I replaced it with the K-line. I am still experimenting, however. For the image below I removed the B-CCD filter and used the Herschel wedge + K-line, it seems there is still enough light.
