All, I have just uploaded a couple of new images of the Horsehead Nebula to the files section in my folder (Rick Gilbert). I would really appreciate any...
Hi Rick, I haven't looked at the images yet, but I can already tell you one big issue that you will be facing. You have too much glass between the image and...
Geez, Rick, that looks pretty xlnt to me. Lovely pinpoint stars, high contrast, plenty of signal, well focused. Other than those problems, it's swell! <g> ...
Hi Paul, Right...well now if I hadn't searched for my FCT150 for a couple of years...but seriously, all that glass is rather HEAVY! I would be very interested...
I wanted to highlight what I suspected would be hydrogen-rich emission nebulae in M81. So I shot the galaxy in the HaGB method I began using in June of 2002. ...
Very nice shot Richard. Reminds me a little of M33 which has those knots of Halpha in the arms. Is this image cropped to some extent. The object is not very...
Hi Rick, Those are nice images but I'll bet there is a lot more nebulosity there. Try using DDP to bring out the fainter details. With your light pollution you...
