Re: Monday 29th July Sun

Alexandra, You said, "...Really I could do with another camera with a 3um pixel size for imaging full discs but I never have the guts to ask the hubby for yet another camera, may be I need to get one second hand." Did you mean a second-hand camera, or hubby? :lol: Love the images. Randall Benton www...

Selling Lunt DSII for LS100

I am selling my Lunt DS II unit for an LS100HaT. I bought it last year but never used it, and I am including a B+W High Transmission Circular Polarizing filter and rubber mounting ring which will reduce “ghost images” far better than Lunt’s built-in filter does. It is very simple to install. $1600 a...

Re: ISS Solar Transit with NO filter

Matt, I live in El Dorado county which is mostly rural, and we get our fair share of fires. Yesterday there were two within sight of our house, prompting evacuation of our neighborhood. They knocked it down quickly and now it is out, but the smoke remains. I shot this with a Celestron Omni XLT 127 (...

ISS Solar Transit with NO filter

I wanted to shoot this ISS transit yesterday, and had everything ready to go. But here in northern California I am surrounded by the many wildfires burning simultaneously, and there is so much smoke/haze in the atmosphere I was able to make a video and this composite photo with no filter at all.

Re: 1st March disk

I love the quality of your FD images. So evenly exposed, with just enough limb darkening to look spherical. It also looks like you are not combining two images (surface/proms) but I still see detail in both. Could you share how you get this look?
Still learning.

ImPPG for color images?

I hope this is the right forum for this question. I currently use ImPPG to sharpen stacked Ha images. It appears to only handle monochrome images. Does anyone know of a similar app that can handle color images?

Thanks,

Re: About ACHF solar corona processing

I have admired his work for several years but I think his method is unique to him. It appears to be a computer process he has developed but (so far at least) not shared openly with the general public. Perhaps still a work in progress. In any event, his results are absolutely stunning. I dare say, "p...

Re: Doublestack H-Alpha, next try. Questions about polarising filters.

If you are looking for a high transmission Polarizing filter, B+W makes a very good one that you can see here: https://www.schneideroptics.com/ecommerce/CatalogItemDetail.aspx?CID=2205&IID=10366 I used one on a double stacked Lunt LS100 to get rid of ghost images.

Alexandra and Robert are both correct. I have seen four total eclipses, and (because of the incredible nature of your eyes) the scene never seems as dark as a photographic record suggests. I tell people it gets about as dark as twilight – just dark enough to see some of the brighter stars. The horiz...
