Hi,

Very nice Mount. I have only Takahashi telescopes but an EM 400 is out of question due to the price and bringing it to Mexico

Re: HELP QUARK

Hi, I am still working on my QUARK chromosphere and slowly but steadily getting better results. I hope to get the Adapter for my ERF for the SKY 90 and then I will try with 12mm more aperture and see the difference. Main Problem is really the bad seeing conditions I have had until yesterday.

Re: Replacing the Rusted BF30 Filter

I think the solar image is much smaller than 5mm coming out of a 450mm scope so this is why you have no vignetting. The full image transmits right though the port hole. I do not use a 5mm BF but I am using a BF30. Below the reasons why I use a BF30 as well as I do not like diagonals as they make li...

Re: Replacing the Rusted BF30 Filter

nobody makes blocking filter replacements because the specifications vary so widely between all the filters and brands. from 5mm to 34mm all the specifications are completely different because they are designed to operate at different focal lengths. The filters are probably hand selected based on s...

Re: Replacing the Rusted BF30 Filter

Unfortunately, it is not usual to have rusted BF30. This is really a pity considering the cost of these filters. This leaves us to experimenting and find more cost effective solutions (at least for imaging) ;-) Hi Christian, ¿ what do we need as filters ? Do you have specifications ... ? I think th...

Re: Replacing the Rusted BF30 Filter

How long have you had your bf30, and are you the original owner? Getting rust on a bf30 from such a small etalon/ objective with its ERF still in place is quite worry some! If you had the thing less than 3 years I would say there is something seriously up with the danger zone coming out of the back...

Re: Herschel wedge option

Thanks Mark, Do you think I need anything else other than the 40nm continuum and the polarizer? (ND3 filter for example or not necessary) I'll be using it on a 152mm refractor. Hi, Contact TS and ask them if it works OK with a 152mm refractor. The following is included with the Herschel Prism ♦ TS ...
