Latest results for the PE on the G-11

Posted By Floyd Blue
Hi all,
Well, I did some more logging last night with different settings for the guiding to find a best case scenario.
I also found a program that would convert the PHD logs to a readable graph in arc seconds. This make it a bit easier to see the trend and curve as well as the actual PE in during the worm period.
Here is a graph of the PE for 1.34 worm cycles, 322 seconds of tracking. The graph shows this as 100 seconds but that is due to my inability to figure out how to change the 1 sec interval it has for the default.
The red line shows the smoothed curve trend for the PE.
The results show just about the same PE in arc seconds that I had thought, 4.3-4.9 arc seconds peak to peak. This is a pretty good result I believe and I am happy with this.

Sorry I have not been posting so much lately

Posted By Floyd Blue
Hi al, I have been really busy getting my new Losmandy G-11 mount and photography setup working together. There has been a lot of little jobs that I had to tackle one at a time. This has kept me very busy and focused. So,
I have worked out most of it now and should be able to keep more current on the forum. grin

Autoguiding question

Posted By Floyd Blue
I have been reading some papers on autoguiding and have some questions for those that are doing it.
I have read today in a paper, that it is better to reduce signal to noise by reducing aggressive movement and making the minimum distance required for instigating a movement larger, rather than making the exposure rate longer. It was stated that by decreasing the time between movements and undershooting the correction and requiring a larger movement to begin a movement, will result in less chasing of conditions and less oscillation in the PE wave.
So, I am wondering what kind of setting you are using.
1) aggression (percentage ie 10 = 100 MaximDL or 100=100 PHD and others)
2) minimum distance ( .xx arc sec or .xx pixel)
3) actual rate in seconds for guiding ( 1.0 sec or 4.0 sec ect.)
4) PEC = on or off
5) DEC compensation on or off

Playing with processing, new processes M-33

Posted By Floyd Blue
Well, I just needed some input as to whether this processing is more realistic. What do you think?

NGC 7331 Deer Lick Group

Posted By Floyd Blue
I got the chance to do a couple of objects last night. Not the greatest conditions, but doable. Here is the Deer Lick Group, NGC 7331.
60 min Lum (10 x 6 min)
24 min each RGB (4 x 6min)

NGC 281 Pacman Nebula

Posted By Floyd Blue
The other was NGC 281 the Pacman Nebula.
Same exposures as the other
Lum 60 min (10 x 6 min)
RGB 24 min (4 x 6 min)

Re: PayPal 4% now?

Posted By Floyd Blue
Hi,
Well, in my opinion it benefits the buyer the most. He gets the item much faster and from all the posts complaining about how long it takes to get something, that is important to many. smile
If you have to wait 10-14 days for a check to clear, 3-14 days for shipping depending on how and where it is shipped to and from, then it can be a month before delivery. Most people will be asking what is up by then!
The charge has been about 3.1% for PayPal. That is what my last transaction shows. However, the charge varies according to variables. If the money is exchanged from one currency to another, it will be 5% or more. Some of my transactions show higher percentages about 3.3-3.5% but no reasons are given for the difference! :S

New Images from this weekend.

Posted By Floyd Blue
Hi all,
I thought I would share a couple of images from this weekend. Shot at the Los Angles Astronomical Society star site in Lockwood Valley, California.
Taken with my WO 80mm APO, G-11 Mount, guided.
First the Horsehead and Flame in Orion.
L = 38 x 120 sec
R = 10 x 120 sec
G = 11 x 120 sec
B = 12 x 120 sec

Horsehead Reprocessed, Good-Bad?

Posted By Floyd Blue
Hi all, I have been working on my last images and am wanting some input. I tried a lot of techniques on this photo and this last one I would like opinions about it. Good or bad, not a problem, just want opinions.
