Subject: RE: FTS formats Sent: Sunday, May 20, 2007 18:10:58 From: Gary Gorsline (email@example.com) The AstroStack developer, Rob, sent me some new files including the FITS file loading module. He said my files worked for him. Now with his new file modules, mine works too. I guess the statement about it working meant after he fixed it. ;) Well, we will see - so far I have it loading some frames. And as to the IRIS that Niall referred to, I downloaded it. It appears to have a lot of stuff, all glued together. It seems to have a bunch of different ways to handle darks, flats, etc., which is one of my next areas to look at, which the others don't seem to handle well. Wrote a program to alter the Meade LRGB FITSint files to adjust by the alignment amount listed in a Registax Project. So, I load up the L files into Registax. Do multipoint alignment but only select one point (the object of interest). and save the project in Registax. My simple program reads that files and makes sure that the object "stays" in one place by changing the number of pixels each frame is offset by as calculated by Registax. It adjusts all 4 colors for a single image. I then ran Meade's drizzle on each set (LRBG) using the object of interest as the center and another star for rotation. The four drizzles were then loaded into adobe photoshop with FITS Liberator and color merged - not bad. Much better than before, and color. First try and lots more to refine. I'm putting this description of the process together very shortly. I have only done one of the seven images I captured two weeks ago (and still hadn't processed in color) using this new procedure, so let me do the other six, and I'll write it all up for you. Thanks again. Gary
Subject: FTS formats Sent: Wednesday, May 16, 2007 09:46:16 From: Niall J. Saunders (firstname.lastname@example.org) I can't remember the details now, but I am almost certain that I wrote that description based on my experiences with Registax v3. I certainly recommend everyone to upgrade to Registax v4 - it is much more powerful, AND less 'quirky'. However, that said, I have hardly used it since it came out (I suppose I am waiting for decent Mars and Saturn images to come along). My current choice now is to use IRIS for deep sky (non-planetary) images and Registax for everything else. IRIS handles FITS far better than any other program I have come across, and it handles image rotation, shift and scale factors with ease. But it takes quite a bit of learning. But, if you are willing to spend time with all the documentation on their website, you really do get a feel for the 'correct' way to approach gathering and post processing your data. Once I get a decent set of planetary data to work with, I might re-post something for Registax 4. Finally, I can't pass any comment on AstroStack - I have never used this software. Hope this helps.

From: Gary Gorsline (email@example.com) Thanks for including me in on this. I'm working with the AstroStack developer to get it compatible with Meade files. I will also look at the IRIS software Niall has mentioned. Another approach - I'm also looking at a way to use Registax to align the main object of interest and then use the Meade drizzle with it's rotational tracking. This would require I write a simple program to take the alignment info that Registax outputs in a project and slip each "frame" that corresponding number of pixels. Envisage does a nice job with drizzle and rotation, but can't track my old ETX 60AT handbox tracker corkscrew path. And I assume that if you use the software from a laptop, that all you are doing is evading the handbox, not using a better tracking software that is in the PC - correct? I'm trying to avoid programming - I do it all the time anyway ;) Thanks Gary Gorsline
Subject: re: tracking Sent: Tuesday, May 15, 2007 22:03:13 From: richard seymour (firstname.lastname@example.org) I've submitted your problem (909 APM blocks operation of 1206 focuser) to Meade as a bug. I'll also look to see if it's possible to patch it. What's happening is that the Autostar sees the 909, and directs focus commands to it. It's a precedence issue. If you're in the Focus menu, and unplug the 909, the 1206 still doesn't work. But if you -exit- the focus menu, and come back into it, then the 1206 -will- work. If you now plug in the 909, the 1206 continues to work (i didn't check to see if the 909's reticle and guider socket become active at that point). If you exit and re-enter the focus menu, the 909 takes over again, and the 1206 falls silent. Lemme poke at it, and maybe Meade will actually address the issue, too (pigs have flown... vertically). have fun --dick
Subject: tracking Sent: Sunday, May 13, 2007 13:13:29 From: Robert Black (email@example.com) I am using a LX90 8in w/#497 autostar hand control. Meade autostar suite. 909 APM & 1206 focuser. My question is should I be able to control the focuser and the tracker from my laptop in the 'image' of autostar suite. I think I have it hooked up properly because I get an image from the telescope on the laptop. Really appreciate a place to go for beginners to ask questions and not have to feel stupid even if I probably am, thankyou, bob

Yes. Autostar Suite's Image acquisition program can control a focuser if it is plugged into the 909 APM's Focus socket. >> I think I have it hooked up properly because I get an image from >> the telescope on the laptop. The connection from the camera to the laptop has nothing to do with the focuser. For focus control, you need the serial connection (a Meade 505 serial cable, which comes with the LPI/DSI kit) from the laptop to the Autostar's rs232 socket on the bottom of the Autostar itself. Your laptop requires a 9-pin COM port, or a USB-to-serial adapter to provide one. If you are able to control the "GoTo" of the telescope from Autostar Suite's StarMap, then you should be able to control the focuser. I recommend joining the Yahoo group "autostarsuite" and the appropriate group for your camera: Meade_DSI or Meade_LPI http://groups.yahoo.com/group/autostarsuite/ http://groups.yahoo.com/group/Meade_LPI http://groups.yahoo.com/group/Meade_DSI have fun --dick
The instructions with the 1206 focuser say to connect thru the auxiliary of the LX90 The 909 says to connect to the other aux port on the LX90. If this is not right, how else could I do it? as it is not operating the focuser when connected this way. Also for the focuser to operate thru the hand controller I first have to disconnect the 909 APM. I really feel for you guys trying to dec ipher what we new guys mean sometimes. I guess a picture really is worth a thousand words. sincerely, bob
From: Richard Seymour (email@example.com) What kind of connector does the 1206 focuser have? If it's a "stereo plug" (like small radio earphones), then it plugs into the 909's similar socket, and the 909 plugs into the AUX port. However, if it's a 4-wire "telephone" plug (i.e. fits into the AUX socket), then -it- goes into the AUX socket, and you don't use the 909 at all (unless you wish the Reticle or Guider functions). To the Autostar, the existence of the 909 overrides the AUX-socketed focuser, and the Autostar only speaks to the 909 for focusing matters. Thus a simultaneous AUX-socketed focuser will be ignored (as you're seeing). If you -do- want the 909's reticle and/or guider functions, then you need to use a different focuser, one suitable for plugging into the 909's focuser socket. Meade's "zero image shift microfocuser" is one such beast. JMI's motor focusers are other examples. If you use the Meade zero-shift, you will still need to manually turn the (existing) coarse focus knob to get "within range" of the more limited zero-shift's capabilities. (i don't know the various Meade focuser model numbers) have fun --dick
Subject: FTS formats Sent: Sunday, May 13, 2007 08:18:38 From: Gary Gorsline (firstname.lastname@example.org) Thanks for all your help so far and the tons of information on your site and associated links. I finally got the latest CD from Meade and loaded the software - seeing has been bad - for last week it's smokey from the 250 wildfires in the state - anyway - I'm putting together my review of several products for you to post if and as you wish. I didn't realize how disjoint the products are. For example, Meade Drizzle does a good job handling rotation, but is not good at tracking. Registax is a excellent tracker, but doesn't handle rotation in a sensible method. I'm taking lots of notes and will get you the details when done. I want to come up with a cook book method of processing images. PS - the FITS Liberator with Photoshop - just downloaded last night - works very nice and good tutorials. SO, my question: I can't seem to get AstroStacker V3 to read in FITS formatted files. I was sure I saw something on your site about it, but can't seem to search to it. I remember something about flipping the bytes ? Can you point me in the right direction. This is the last product I've got on my list to review. Gary Gorsline Land O' Lakes, FloridaMike here: Is this what you are looking for:
Yes, I've reread that article 3 times in the last week. And I can get Registax to read the Meade FTSint files as Niall describes, however, Naill only mentions that AstroStack can read FTS files, but he doesn't give any details, like he does for Registax - however, I do suggest to anyone to read the Registax V4 help before trying Naill's procedure - Naill left a few important items out - especially the naming of LRGB files. However, AstroStack 3.2 (could be lack of correct procedure - UI is somewhat confusing) doesn't read any of the FTS formats that Envisage writes. It reads other format files fine and I've been able to play a bit with it. I have gotten a quick response from the developer and he wants some sample files, so let's see where we go. Gary
