I was looking at the data I had of M97 and noticed that it seems there is an outer ring in the OIII. I pushed up the data and looks like just above the...
Hi Robert, I noticed the same secondary shell in some long exposure luminance exposures I did last month of M97. However, I wasn't sure if the outer shell was...
Hello all, Hope this finds you all well! I wanted to share with you my first serious attempt at narrow band imaging. Details should be under the image and...
This is 3 hours of OIII with 20minute exposures. The filter is 8.5nm and the scope is an 8" F5 newtonian. Going to have to revisit it again and see if I can...
Hi all I have finally managed to get out and do some imaging for the first time since mid February. It was also a chance to try out the H9 camera and 7 ...
Nice first light on your new gear, Gordon. How did you end up combining? Do you really mean HaRGB, with the Ha as luminance, or is it really HaRGB as...
Very nice first post, Gray! My only suggestion would be to try a Shadow/Highlight adjustment (on the bright end) to reveal just a bit more of the Trapezeum...
Neil, this brings to mind a question about combining techniques for Ha data along with R, G, and B. Would you be so kind as to discuss the various combining...
Hi Neil Thanks for the comments, I will have to try your suggestions when I have some more time. In answer to your question the Ha is a straight forward...
Hi again As usual when I post my images, I looked at it on a different computer and monitor and saw a bit of a gradient so I went back to the drawing board and...
Hi, Up here, 65N, astronomical darkness is fainting away In a few days. I have to quit imaging untill Autumn. Next dark night will be at September 8. Here is a...
"At 65N that makes for some excellent winter imaging, eh?" Neil, your Canadian roots are showing :))) Good one ! Cheers Lynn Hilborn...Whistle Stop Obs ...
Hi Guys, Winter up here is dark, but very cloudy doe the Arctic Sea. It sends lowpressures after an other. Moust of the images are taken between the clouds...
Hi all Sometimes bad weather can be a blessing in disguise as it allows a bit of catch up time in the processing department. I posted this image here and then...
Hello dear Users of our APM/TMB/LZOS/LOMO/Apo Refractors. Some of you may have heard that we starting now APM America and we will have our own webside. By the...
Hi All You must be getting fed up with my reprocesses but I have to keep myself sane when the weather is bad. Following tips and comments from various people...
Hi Neil! The budget... that is a DIRTY word! I don't have enough for a AP900 or a Paramount but a new G-11 <$3200.00> is "doable". The next step up would be a...
I've have the AP900 with a TAK150 TOA but my "portable" is the EM-200 with an Astrophysics 130 StarFire Gran Tourismo. The EM-200 is a remarkable mount with...
Hi Rick, Do you use the EM-200 mount to collect 30 minute subs? How does it perform? Have you done any studies looking at the PE? Not that I care about the...
Brian: You know, I haven't measured the PE curve with PEMPro but I will next time I set up. It's known from the TAK group to have a very fine, tight curve. ...
I think that you can get special gears for the G-11 that improve its performance...that might work well. For an FSQ alone, an EM-200 would be ideal. $4K is...
Rick, No need to go out of you way and measure the PE in your EM-200. If it can keep stars round with your TOA/ST-10 for 50 minutes; PE is meaningless. I have...
Hi Neil, Yes, there are some special gears available but the cost of them added to the cost of a new mount put the G-11 almost into the same price category as...
