Re: Photographic Benefits of UV/IR Blocking Filter

I use a Baader UV/IR filter for Ha and it definitely cuts out a slight foggy blur from far red light getting in the camera. When I first started CaK imaging with a Lunt B600 I used it and was very disappointed until I realised that it cuts out most of the CaK line! Only a very faint blurred image le...

Re: Lunt CaK module testing 22nd April

Hi Alexandra Really interesting. I looked at your comparison images and aligned a part of Stuart's with yours. I think the y axis resolution is the same as Valery says but the x axis is smeared left to right by at least the minimum resolved image part. CaK test copy.jpg I have aligned a part roughly...

Re: Hydrogen Alpha Upgrade

2. New Lunt / Coronado scope - we are talking circa £2.5K+ for a basic 60mm B1200 and nearly twice that for a DS model :o Plus these will have similar sweet spot issues as the PST (as I understand it).
