Re: multiple images

Well after thinking we will send the filters back, I thought about Peter Zetner's Omega Ha scope and also Filips Scope both using the rear blue filters etalons. Peter used two and Filip used just one because he had the same problem with his red one. I decided to have a go with the two blue filters (...

Re: multiple images

Thats expensive I have taken great care with them especially after seeing the first image and not being able to move the false images by tilting thought they may have to go back. Very expensive in time and money for me so I don't feel inclined to try any other Omega filters at the moment and Bob who...

Re: multiple images

I did think of that when I had the PST that was before any one had done it but didn't have the guts to have a go, (very unusual for me) I wanted to keep my eyes. My PST was one of the first ones.

Re: multiple images

I have had a PST but found although the views were good I wanted to get closer in and study areas more but found it very limited for that so didn't use it much. I must admit though imaging and processing has come on so much since then I probably go more down that road now.

Re: multiple images

Yep Mark I am coming to that conclusion Peat Z ended up using two of the rear filters and other blocking filters in his scope, he even mentioned in one of his posts that he tried to separate the front filter but it could not be done. So after spending a £100 or so on fittings other filters and alumi...

Re: Sunday PST fun from the bedroom

Why not have a small micro balcony with a railing and smoked glass lower then the doors can open inwards and all is safe.
Then we can keep having your excellent pics and we dont need a solar scope.

Re: multiple images

Do you know if Wolfgang worked for Zeiss at any time?
Oliver Smie of Bel Optik did and he also makes a very similar unit.
Lots of excellent opticians were put out of job when the Berlin wall came down and Zeiss west managed to take over the Jana factory.

Re: multiple images

Hi Alexandra Just been on your solar nutcase blog and see you did get it working, nice! Surprised you have not seen the pollen before, maybe modern filters are to narrow. I have seen them and many other high altitude objects in other solar filter systems thousand oaks, PSTs it is a common thing to s...

Re: multiple images

Hi Alexandra Yes I think he does now but his original Omega was a Ha system and he also had trouble with the first filter and reflections and from what I can gather he used some different pre filtering and two of the rear filters that do not have the UV/IR protection filters. It seems to me that it ...

Re: multiple images

yep ghosting is a problem but I have found CPL filters can remove nearly all but these secondary images then the contrast improves, band pass I am not sure about yet, I am getting good prominences but surface detail is not good yet I can see some. Im not sure how good my seeing is and there is littl...

Re: multiple images

Yep thanks for the reply Mark that is the conclusion I am coming to. I have two sets of these and both are the same, although the reflections in one is slightly closer than the other. It is a pity the elements could not be separated and mounted separately then the reflections could be removed. What ...
