These look great Lou...well done

I was hoping to get out yesterday as well but the clear skiers disappeared before noon which shot my lunch time observing plans out the window. Nice to see you manged to produce soem images.

Hi Robert...

Both images look great considering the low elevation of the sun

The 3x is very sharp, but the 5x still looks very good. A 4x might have delivered a bit more resolution but still excellent results.

Hi Derek...

That is a quite a collection of pics. Awesome landscapes and scenes

Very sharp images Raf...well done

Great FD images Pedro

Hope the approaching storm doesn't affect you too badly.

Back to the Ha filter specs...

TheSkyBurner...good to know it has promise. I wasn't sure if the IR leak as beyond the 1,000nm and didn't show up on standard plots.

Brian

Superb images and animation Marty...well done

Ironic that you have had frost, just shy of hitting the freezing mark here.

Hi everyone... A couple of questions to pose here as the discussion evolves. First, in the spring of 2017 when I got the Airylab telecentric I met Frédéric at NEAF and he suggested adding a Ha filter in image train. Their telecentric has a 1.25" filter mount before the amplifier optics and can be ti...

Thanks for your feedback Eric and Rainer...very much appreciated

Mark and Franco...

Thanks for your comments, they are always appreciated

Hi everyone... I too was out for a short session over lunch today and captured a few full disk and the main prom on the western limb that showed a lot of details. The images below are disk/limb composites taken with the LS75 etalon on my Williams Optic 72mm, f6 APO and B1200 blocker. The first is pr...

Great images Dave...well done !!!

Hi Lou...

The proms came out well with all setups. I think the C9.25 did a great job with the chromospheric details as well.

It is too bad that some places on earth suffer from the pollution as shown in the pic posted for the 'televised sunrise'. I suspect that unless there is major change in thinking these places will continue to degrade. I only hope that clearer minds will continue to push efforts to preserve the enviro...

Nice to see you pull out some detail despite the low activity!

Beautiful images again in this session Pedro...well done

Brian

Hi Pedro...

These FD's are as sharp as the previous day, but the hi-res granulation is excellent. I like how we can see short instances of better seeing...great to have the image processing capabilities of today.

Brian

Beautiful FD images Pedro, too bad there isn't much going on. At least there are a few filaments in Ha

Brian

Hi Lou...

Great these images the LS80T/Quark DS setup. As you say, would be nice to have more interesting targets to image!

Brian

Bart, Stu, Raf, and Derek... Thanks for all the feedback on the setup. Cloudy/rainy Thanksgiving holiday weekend has set in here, so more testes will have to wait. Maybe a nice big AR will appear next week to use as a test subject ;) Raf, I use the extender to bump the focal length/image scale. I al...

Raf... I see that Explore Scientific has just introduced a 2"version of the 3x extender. It isn't as much an issue with the Ha system (1.25" blocking filter), but I prefer to reduce as many adapters (2"-1.25") as I can to keep the collection of optics as well aligned as I can. If it will fit ahead o...
