There was a recent thread about MaxIm spending a long time "Reading" before actually "Downloading" an image from an STL-11000 but I didn't see a solution. I have the same issue with an STF-8300. I don't have the answer but I have a little more info on the problem. Maybe someone will think of something.



Here's what I've found:



I'm using an older Dell (about 6 years old) running Windows XP. I just upgraded MaxIm in December and installed the latest SBIG drivers. When taking light frames longer than about 1 minute the "Reading" status shows up before the "Downloading" status. The length of time "Reading" appears is variable. For a 1 minute light frame it appears for about 1 second increasing to 15 seconds for a 10 minute light frame. "Downloading" is always a little more than 2 seconds. What's very strange is that "Reading" does not appear after a dark frame. I only see "Downloading" and for 2 seconds. How can a 10 minute dark frame be different from a 10 minute light frame?



I also have MaxIm installed on my iMac in the house running under Parallels. I ran this same test and "Reading" never appears after a light frame of any length of time. "Downloading" takes a little more than 2 seconds just like the Dell.



I also have an Orion SSP camera and it exhibits a variation of the problem. Although I've never seen "Reading," the download time varies with the length of the light frame with shorter duration light frames taking a few seconds longer than 10 minute light frames.



The question really is what is MaxIm doing while it is displaying "Reading?" I'll bet it's not actually reading data from the camera. If I could find out what this means the problem might be able to be solved.



Thanks - Chuck

I always assumed that "Reading..." was the camera itself reading the

data out of the CCD and into the data buffer which is then transferred

to your computer over USB.



It's odd to me that changing computers would make this take a

different amount of time.

#52549 Mar 15, 2013

That's logical, except "reading" also shows up with cameras that don't

have an internal data buffer.

Thats because the different pc has a faster single core processor.

I'd buy the faster processor idea except that a 10 minute dark frame has 0 seconds of "Reading" and a 10 minute light frame has 15 seconds of "Reading" on the same computer. Also a 1 minute light frame has 1 second of "Reading." What does the integration time or the type of frame have to do with downloading?



I think the problem is we don't understand what is happening during "Reading" time.

You would have some delay... It's in the Maxim Manual "





MaxIm DL simply disables guider calibration during image download for all camera models. "



This is not my reported issue.. This is an ongoing issue with multiple users.. Users have made custom scripts to stop the image sequence and reacquire the guide star because of this issue.



It's not a guide delay.. it's the maxim lockup/hang when downloading the image from the main camera.. It says reading then downloading in the exposure/status windows.. When reading and downloading occur, all processes in maxim hang for a few (or longer) milliseconds..



You might not see it if the maxim windows is just sitting there exposing.. You would notice it when using an AO or manipulating your images while exposing.



It happens as well when using an OAG and not polar aligned within a few arc min. The download happens from the main camera, the guider hangs ( stops exposing and guiding until the download is complete) then the guiding continues. If the star moves a few pixels because of polar misalignment, during the main image download, you will get a star fade error (especially when subframing your guide star is a very small window). You must add a 30+ sec delay after each exposure for the guide star to be reacquired...



Using the AO feature and AO dithering, this really becomes an issue..



This issue is also addressed in Maxim's user manual





"When taking exposure sequences with the main camera, the guider must stop during image download. There are several reasons for this. Some cameras use one shutter for the main sensor and guide sensor, so the guider cannot continue during download. Many cameras hog the CPU during image download, preventing the guider from operating properly, or preventing the guider correction pulses from being generated correctly. Other cameras would produce image artifacts if the guider was consuming CPU cycles during download. Filter wheel internal sensors can also flood the sensor array with large amounts infrared light, which can cause image artifacts due to charge traps in the sensor. Although some cameras can happily guide and download at the same time, most cannot. Due to the extremely high likelihood of problems, MaxIm DL simply disables guider calibration during image download for all camera models.

One problem with the autoguider pausing is that some camera models take a very long time to download (sometimes up to a minute), and during this time the tracking can drift. By default, MaxIm DL waits five seconds for the guide star to be reacquired and settled before starting the next image. You can increase this delay time using Expose Tabwww.cyanogen.com/help/maximdl/HIDD_EXPOSE.htm> settings. Alternatively, you can set up a Guider Settling Criteria, so that the next exposure will not happen until the guide star is close enough to center (see Options menu below). "

Perhaps this is due to a timing difference ?





Software tells camera to expose X seconds and the Computer keeps track

of the elapsed time as does the camera. And the software is waiting for

the camera. PC clock says it should be done. Camera says No - not quite

yet. The delay is always worse the longer the exposure. And zero for

Bias frames.

i may have been the one initiating that recent thread. this "feature" has frustrated me since i started using maxim. i have done numerous tests with duration of exposure, darks, lights, bias, etc. i have seen real data (light frames) take up to 90sec to read/download while 30min dark frames take 32sec. one thing that seems certain is the image content affects the results. i've given up keeping track of it.



i switched to maxim from ccdsoft because ccdsoft was too out of date to keep up with a new camera/filter wheel combination i was using. but regardless of type of image being taken, the read/DL from ccdsoft was consistently 32-34seconds. just plain weird what is going on with maxim and i have given up trying to understand it (or make it go away)

I can see that you must be right, but I guess my downloads are so fast and

grab my attention that I never noticed.



I can also say that I've never noticed much change in guiding between

exposures. It's funny I noticed that guider settle time setting and always

wondered what on earth it was for. Live and learn.

but continue to use the product..



I don't "see" (unless it has happened and I have not seen it) the star fade

issue.. I'm thinking because of my polar alignment and perm mounting.?



It's just constructive criticism. Maxim 5 came out in 2008?



Maybe this is all moot and Doug and the guys are secretly designing Maxim 6!

Ya true..



How come I can do digital video with maxim at 15fps 1600x1200 and guide

without the issue? Theres a whole lot more bandwidth used in that video

stream that any 20 meg sigle frame download....

I'd buy the faster processor idea except that a 10 minute dark frame has 0

seconds of "Reading" and a 10 minute light frame has 15 seconds of "Reading"

on the same computer. Also a 1 minute light frame has 1 second of "Reading."

What does the integration time or the type of frame have to do with

downloading?



I think the problem is we don't understand what is happening during

"Reading" time.
