Hi Dorothy, I'm not one of the moderators, but I might can offer a little advice. The moderators won't be able to help you here. If in fact your digest...
Thanks, Nick, The problem seems to be resolved as I am now receiving messages. The same thing happened with another Yahoo group to which I belong and I wrote...
... Ken Whitnall and Philip Blanda will need a good memory for this one. Perhaps one of the technical people at Lunt will be able to help out. BUT Can anybody...
Hello Gene, For the Baader C-ERF it is red glass and it has special IR blocking coatings on the one side which gives it the blue colour and goes a long way to...
... Thanks, Ken. The 28 layer coating (and the Baader web site itself, IIRC) means that this particular part of the filter works by reflection. Reflection...
... Another question for Ken: This one, from your Post #1946, October 20, 2008: You say that, in addition to tuniing the filter, you sometimes have to refocus...
Hi Gene, I will be curious as to Ken's answer for this, but... From my understanding of the mechanics of the system, re-tuning the etalon changes the tilt of...
Hello Gene and Bob, I'm not sure of the mechanics of the situation regarding focus but I have thought about it and I would like to learn more. While observing...
Hi All: Can anyone answer this qestion for me: Is the LS60T50DS/B1200 now actually a 50mm CLEAR APERTURE when it is in double-pass mode because of the revision...
Hi Ken, In message 2679 Ken Florentino (I really liked your solar setup and presentations at past Star Stares, Ken), he gave us calculated focus points for the...
Could it be lack of field flatness due to the etalon(s) or something else in the focal train? I'm always fiddling with the focus anyway due to changing the...
Hello Mark, This is what I am thinking, there is a lot of various optical reasons, OTA eyepieces etc. that would make the FOV not prefectly flat. I do fiddle...
I have some observations on its performance which I wish to share to see if other people have similar experiences or not. I have used it visually and also...
Hi, all, I've been looking at some photos of the sun on the various sites that post them. I want to see what H alpha images are supposed to look like. So I...
I am sort of answering my own post. I just discovered the Solar Live site and I may be able to get answers to my questions there. But I would still appreciate...
Hi Dorothy. Have a look at Jan Timmerman's site. He belongs to the Coronado_PST group but has a wealth of information on everything from the sun and planets...
Dorothy - There are several sites to see great solar Photos/videos, and the one I use the most is the solar forum on CloudyNights. Many of the posters there...
Gene: When I do high resolution imaging (f/10 to f/30), I always need to refocus when imaging surface details depending on its position related to the solar...
Hi Dorothy, Ken and all, There are two sources I use that tell us what is going on on the Sun: http://nsosp.nso.edu/VIDEOIMG/ospan/ , and Spaceweather.com....
David, I'm replying only to the last part of your post... My LS60THa tuning knob operates the same as yours and I have the same question in my mind if its...
Just to throw a comment out there... I haven't received my Lunt yet (soon though! yeah!) but I have heard several people say similar things as to the...
Hi Dan, Have you received your bino add-on yet? How does it work? I am very excited to hear how the views are through your scope! Thanks! Adam ... you all...
