Hi

I suppose it does not hurt that the SGP authors are Pixinsight users   :D 8)



Harry


This whole thread sums up why I got fed up and am abandoning MaximDL.  There is just something wonky going on between PI and MaximDL (and MaximDL hasn't done an update for what seems like years now).  I get my MaximDL captures to work most of the time, then bang, all the same settings but something goes amiss, mostly with NB images.  I am sure its just a glitch in my system somewhere, but I am tired of the fight and have switched over to Sequence Generator Pro as my capture software (based on recommendations from Harry and others to a query I made a few weeks ago) and couldn't be happier.  Shot all new darks and bias frames in SGPro and PI handled them all without the slightest hitch.  Will test for the first time in the field this weekend, but expect the same much smoother connection between PI and SGPro than I ever had with PI and MaximDL. 

Sorry to rant, but MaximDL has been driving me crazy until I just couldn't take it anymore.

Thanks for letting me get that off my chest.

?? I get several updates a year.

I own both SGL and Maxim and I think the sentiment here is that Maxim needs a bit of an overhaul. It feels like a program that has grown slowly without being optimised from scratch again. SGL has its own foibles but Maxim's general stability on a computer that is optimised and dedicated to astronomy is not great. Obviously PI users are a breed apart in the ergonomic and way-of-doing things but SGL does appear to be more coherent. Dare I say it SGL=OSX and Maxim=Vista. ( I use Mac's and PC's professionally and I don't have an axe to grind, just an observation).

Chris

Geoff,

I'm a bit surprised to hear that.  I checked again and MaximDL has been stuck on version 5.24 for as long as I can remember.  Maxim doesn't date its release notes so no way to tell when that last one came out but it was some time ago, though possibly in the last year (but if so certainly its been over 6 months at a minimum, and I am betting a lot longer than that).  Every week I check for updates on all my astronomy software and in the course of a month almost every package has some form of update or enhancement but as I said before, I simply cannot remember the last time I got anything other than the page telling me that my version 5.24 is up to date.  That either means all the other packages are seriously flawed and MaximDL is perfect, or all the others are still making an effort to address issues and add improvements and MaximDL is resting on its former glory. 

And others seem to be fixing MaximDL issues even when MaximDL ignores them.  Just a little while back, I started to get strange new artifacts with MaximDL captures in the form of blacked out regions in saturated stars.  And the problem wasn't showing up just in PI, but also happened when I took those images into Nebulosity or CCDStack 2.0 to test them.  Then, several weeks ago, CCDStack put out an update that fixed the problem, at least there.  Still happens in PI and Nebulosity.  So now I need to take my images into CCDStack and convert them before I import them into PI for processing.  Now its likely that this is just a glitch in how my system works, but why was CCDStack aware of it and willing to add a fix, but MaximDL seems to be ignoring it. 

Its this kind of constant upset and MaximDL's seeming lack of interest that has finally caused me to throw up my hands, which is a damned shame since its great capture software and works seemlessly with both my Hendricks Focuser on my Planewave CDK12.5 and with PEMPro 2 which I use to perfect my polar alignment in the field.  So I will keep using it for setup but then abandon it when I start capturing lights (hint, hint, if SGPro is listening and can add support for both of those packages, I will abandon MaximDL altogether, and happily pay for the add-on).

My bet is that MaximDL has stopped supporting Version 5 because a new Version 6 is under development, but that is just a guess.  Whatever the reason, I am done being frustrated when the developer does not seem to care.

Again, sorry for the rant, but this is a nitch hobby and we non-programmers rely heavily on the developers to keep things working and moving forward (just look at the progress PI has made since MaximDL issued even a minor update).  Its the ones who are making that effort that I want to support, hence my switch to SGPro.  From everything I have seen, that developer is interested in making his product the best possible and he is giving it his active attention and support and as such I expect to stay his loyal customer.

Hi Jim
I guess memory plays tricks with us. Your "what seems like years" and my "several times a year" are both wrong.
I had a quick look at SGPro just because I don't like Maxim's yearly subscription system, but the need to get PinPoint for plate solving (Maxim includes a lite version) and the fact that I use a Hedrick focuser and Pempro decided me on sticking with Maxim.

you can plate solve with elbrus (free) and astrometry.net (free) when using SGP…

JKMorse   +1 - I fully agree - we should support those who support the community. Several bugs that crash Maxim DL have been repeatedly reported and ignored.

That's why I'm going back to school with PI. It will be worth the effort in the end.

Buzz,

Stay with PI, you won't be disappointed.  You sound like a seasoned imager so this will probably not be all that helpful, but here is an earlier version of my PI cribsheet that I have put together and keep updating to keep things straight for my old brain.  This is version 13 and I am up to version 19 now, but I am at work and the other is on my astronomy machine at home.  If you are interested in a word version of the latest iteration, just drop me an email and I will happily send along.  And with the word version you can tweak to your heart's content to make it fit your own needs.

Best,

Jim

I don't want to hijack the thread but since I am struggling with this also....

Just run BPP to test for the n:th time.
10 flats
10 darks
10 bias
just one light (testing)

Output is in attached file.

** Warning: No correlation between the master dark and target frames (channel 0).

I must be doing something wrong here....

Thanks for your excellent crib sheet. I stole it. Hope you don't mind  :)

But now I am getting confuseder and confuseder.
On page 5 Image Integration you mention the use of a reference image??? I am missing something here now.

My ImageIntegration tool has no such thing. My Star Alignment tool does but not the integration tool.

What am I missing?

the first image in the list of files in ImageIntegration is the reference image.

this is the image that all others are compared with (statistically) and image weighting and normalization are relative to this frame. the reference frame weight is 1.0 and the other frames will have some fraction or multiple of that weight.

Ohhhh... I have managed to miss this piece of information. I blame it on information overload (but I might just be a bit daft)

Thanks for this info.

Now, if I only could learn how to interpret the SubFrameSelector I would be on my way to finding good images  :)

Have you looked at the documentation http://pixinsight.com/doc/scripts/SubframeSelector/SubframeSelector.html ?

Or if you don't like that particular reference image for some reason, you can click on another one and then hit the "set reference" button on the right of the panel.  This will move the selected image to the top of the list.
