  1. OK. Telescope for observing is a very complicated topic as you probably realize by now. Please understand that if you want to observe DSO with any telescope. you need to have access to a very dark site. Aperture size is king when it comes to observing deep space objects. Also notice that the difference between a 8" and a 10 " telescope is not that great. I have 5" refractors, SCT 11" and SCT 14, and a 12" Dobsonian. The difference between the 11" and the 12" is negligible, but the 14" is definitely noticeable. Now your budget is key, but I can tell you that my SCT-14 with its CGE equatorial mount is not very manageable for transporting, which is why for our star parties ( Southern Cross Astronomical Society ) I purchased Orion SkyQuest 12" Go To Dobsonian truss. Truss is key for portability. The same scope with a tube instead of the truss system is a monster , but the truss dob comes apart into 9 pieces which I can assemble in less than 10 minutes ( I have clocked it several times ). Now is a Newtonian system and requires collimation( people get scared when they here collimation...) I do not have any collimation tools ( Chesire, Lasers, etc, )and I can collimate this scope in less than 5 minutes once you have done the initial set up. Food for thought ! Enjoy the views... Jorman PS: Not recommended for astrophotography
  2. I have CCDSoft and TheSky6 Pro integrated. I am running them as the administrator. I have all the interconnected server functions enable I can image link and get the image equatorial coordinates in CCDSoft "Insert WCS " dialog box, but when I click on the "continue" button to plate solve the image, I get error code 206 ( 0xce). I have discussed this with Tom Bisque and at this point we are running in circles and I am quite frustrated with the problem. Can anyone offer any help ? I am using Windows 7
  3. Hi folks, I just got CCDIs on a trial basis. When I try to align and register two sets of data from different nights , the program does register and aligns them, but I guess do to a slight rotation between sets, the final image shows like a cut off edge , so in reality the images are not really aligned. Is this normal ? Aligned images showing offset.TIFF
  4. Hi you all. I recently began taking large numbers of sub-exposures over several nights. However, I am looking for a simple way to take the images in a way that I can stack them without a lot of variation in the registration process. I have read a lot about plate solving, but frankly the explanation I have read are too technical for me.. . I have CCDSoft and The Sky 6 software. Can someone explain how to use it with these softwares in simple terms and a step by step like procedure ? Thanks Jorman
  5. Hi folks, Attached is a combined 10subs x 10 min image of the Horsehead nebula. Same train. Cleaned filter and reducer, bit the real culprit was reflection. Not internally, but externally. Turns out my neighbor installed a new halogen lamp on his backyard and it was on the line of sight with my scope. I put a sheet across my areca palms to block the light and the problem went away, Go figure ! That is astrophotography....
  6. OK Thanks for responding. I will look at all the surfaces on the train and then take the same image without any reducer and see what happens Jorman
  7. Attached is an image taken with an ED-127, o.8X Astronomic reducer and an XCM2000 OSC camera. It is a 10minute exposure. I have never seen this in any of my prior pictures I have taken with this set-up. It was taken with CCDSoft( I normally use CCDOPs). The lens did not have dew ( I have a dew zapper and I looked at the lens immediately after taken the image). The dessicant on the camera was just refreshed a week ago. The moon was not anywhere near where the image was taken. The train has a Hutech LPS-P2 filter. Any ideas what could be causing this ? I took over 10 images throughout the night and they all show the same effect. I even try a different reducer.
  8. Hi all, I do not know if this is the proper place for my question, but here it goes: I am trying to improve the periodic error on my CGE mount using Celestron PECTool. I have read a lot of posts all over the place, but I have to admit that this topic is quite confusing mainly because the instructions provided by Celestron are quite incomplete. I am looking for someone to explain to me in simple terms, step by step, how to use this tool. I have gone as far as doing batch training with 5-8minutes runs and uploaded the data to the mount as per the tool instructions. Questions : 1. Is the data for those runs stored somewhere in my computer or they just reside in the mount memory ? 2. How do I use this information to reduce the error while I am guiding ? 3 .Do I need to do something with my Hand Controller the next time I get ready to image ? I have a dual chip SBIG XCM-2000 which is selfguiding. As you can see I do not have a clue here Need help !!!! Thanks, Jorge
  9. I have been in contact with Astro-Video already. Unfortunately their F/1.8 reducer is design for F/10 SCTs and they do not know if it would work with SCT C14 which is F/11. Jorman
  10. Hi guys, I really appreciate your responses to my "goodbye" thread. I think that in my case the problem is that my SCT C14 has an extremely long native focal length: 3,911mm. As such it requires an extremely fast FR to get a decent live image in less than 45 seconds ( my personal limit for considering live imaging ). A Hyperstar lens could probably do it, but as I explained in a prior thread I am bias against Hyperstar lenses on a C14 scope, I know because I had one for years. The problem with the Hyperstar is that it get stuck to the corrector plate and it is a scary thing to get it off. I am not the only one that have experienced this problem. So maybe someday someone will invent a fast F/1.8 reducer for my scope that could be attached to the visual back. If they do, I will definitely try live imaging again. Regards to all, Jorman
  11. Gentlemen, I have returned my Ultrastar C camera back to the vendor. He was kind enough to accept it with just a minimal restocking fee after hearing my arguments. I believe this field of imaging is not quite ready yet. I have seen some of your beautiful pictures, but the fact remains that most of those shots are taken in pristine skies and usually with multi-stacking of subs. If an image needs to be stacked, let's say 20 subs for 20 seconds each, that is over 6 minutes looking at the image. Hardly what one will consider live or near live imaging. My initial intention was to use this camera for outreach programs in our community, but no one is going to stand up behind a computer screen for over 5 minutes to see an image when they can walk to a telescope a few steps from the computer and look at a planet, or M42, etc. I think the cameras in the market are a good start, but until the average user under average light polluted skies can get a fairly nice looking image without much manipulation in less than 30 seconds, this field will remain a very small niche in the scheme of things. The vendor did not even want to sell me the Lodestar 2X color because in his opinion the marginal gain in exposure time was not good enough for my application. So I thank everyone that sincerely tried to help me out. I will remain on the look out for further camera improvements and hopefully in the near future I will join you again. Sincerely, Jorman
  12. I thought I had already reply to the latest posts, but I guess it did not go through. I will start by saying that the images I posted were just examples of the many things I tried last night, including all the stretches available, black clipping, white clipping, etc. The fact is the Ultrastar C with my telescope trains just does not work for what I consider live imaging. Now, I very seldom if ever, participate in this type of forums because invariably there is going to be some of you that think to know all the answers without really understanding the questions. Those people are really trying to mask their own deficiencies. I usually do not talk about myself, but I think there is a need here to say that I have multiple degrees from very reputable universities in the USA. I have degrees in Chemical Engineering, Chemistry, Physics, and a Master's degree in Business Administration and I have four patents in the field of photo polymerization. Before I retired I held very responsible positions in major corporations. Yes, I can read, understand, and apply the very simple equations involved in astrophotography. I think if you guys do not have anything positive to contribute, please do not. I want to thank Paul, Don, Martin, and others that clearly have the sincere intention to help and positively contribute. Jorman
  13. Hi and thanks to all that has responded, This is the first time I have participated in a forum of this kind and the reason is that there is always those of you that think to know all the answers without even understanding all the questions....These people are usually trying to mask their own deficiencies and will be better off not even responding to the posts. If you can not offer any positive criticism, then keep it to yourself. Some of us are not idiots and contrary to what some of you may think may know more than you do about the subject matter. I usually do not like to talk about myself, but I think in this case some of you should know that I hold multiple degrees in Chemical Engineering, Chemistry, Physics, and even a Master's degree in Business Administration. Before I retired I held major positions in several USA corporations. Yes, I think I can understand a few of the simple equations involved in astrophotography. As I said from the beginning I just wanted to see what live imaging is all about for outreach programs specifically. I have done all the stretches and gyrations you guys are talking about with Paul's program and this camera just do not work for what I intended. I already put it up for sale in Astromart.... I want to thank Paul, Don, Martin, and others that clearly know what are talking about, for responding to my cry of help with sincerity and a clear intention to help. Regards, Jorman
  14. As you guys requested here are some screen shots of the Horsehead nebula settings at 10subs x 20 second with SCT C14 x 3.3 Meade reducer and a Hutech PLS-P2 filter. I am also going to try to post some raw images, but I believe the size is too big and photoshop does not let me process FIT files to reduce the size. I tried many other targets, but they all look lousy even stacking 20 subs at different exposures from 20 secs all he way to 45 secs. Like I said before, this is not live imaging anymore. Jorman PS: As I suspected it does not allow me to load anything else......
  15. OK. I will start with SCT C14 at f/3.3. I do not believe I have the proper adapters to put the Celestron 6.3 reducer in the Astroview, but I will see if there is some combination that I can improvise. Thanks again, Jorman
