Subject: LPI Sent: Thursday, June 22, 2006 07:28:48 From: Jasmin Pindzic (firstname.lastname@example.org) I just would like to know if I can use the LPI for deep sky images, and how is the quality of the image is going to be. Do I always have to click on START BUTTON when I want to use the LPI, OR just when I want to start taking images. How do you reduce the focal. I don't know much about LPI camera please help me out here. which camera is the best for deep sky images (DSI, LPI, or CCD) Thank you very much. Jaz.Mike here: There is some info on using the LPI on the Helpful Information: Astrophotography page. Yes, you can get images of some DSOs using the LPI although it is not ideal for them. The DSI line or one of the many CCD imagers will be better. Of course, many people use modified webcams. Again, see the Helpful Information: Astrophotography page. There are focal reducers for the ETX. See the Shutan Wide Field Adapter on the Accessory Reviews: Showcase Products page. Scopetronix also has a focal reducer for the ETX.
Mike thank you for your advice. I found everything I need on that web site that you provided in your e-mail. Thank you again Jaz.
Subject: LPI with ETX-125PE Sent: Monday, June 19, 2006 04:14:39 From: Jasmin Pindzic (email@example.com) I got a question on how to get my LPI to work. I was trying to see the Saturn last night trough the ETX-125PE using LPI without the success. I couldn't see anything on the screen when I connect LPI to my laptop, looking trough the eyepiece I could see the saturns ring. I am new to LPI and I don't know much about it. Could you please tell me how to use the LPI, I think I'm doing something wrong. Thank you very much. JAZ.Mike here: What settings were you using in the software? It sounds like either you had a too short exposure time OR Saturn was outside the field of view of the LPI. Have you ever seen an image of any object, terrestrial or perhaps the Moon? Remember that the LPI is like using a 6.7mm eyepiece.
Thanks for the quick respond to my e-mail. I was using the software that came with my LPI (AUTOSTAR SUIT). I have never seen any object trough my LPI, this was the first time for me to use the LPI. The first thing I did was, I put 26mm eyepiece to center the object first, than after the object is centered I would take eyepiece out than I would put LPI cam into my telescope. When I put the LPI into my telescope all I see is something like stars in different colors but I don't see the object that I centered with my 26mm eyepiece first. When I turn the LPI toward the light without putting it into my telescope I could see some lights very blurry, which means my LPI camera is working. You said that LPI is like 6.7mm eyepiece which is very hard to center the object. Do I have to use my LPI with eyepiece, OR I just put the LPI in my telescope without any eyepiece? Thank you very much for your help. Jaz.Mike here: The LPI is used in place of an eyepiece. And yes, the FOV is narrow. And it does need to be refocused. You can focus it and then replace it with an eyepiece. Slide the eyepiece in and out until you reach a focus WITHOUT using the focus knob. Then make a mark on the eyepiece tube (or use a parfocal ring). That lets you repeat the focus with the LPI the next time. I suggest checking things out in the daytime or a bright and large object like the Moon.
I sent you an e-mail before this one but I forget to ask you this question, what settings should I use in the LPI software. I open the LPI image screen than I click on (AUTO ADJUST). Thank you.Mike here: Take a look at "Mike Covington's LPI Notes" on the Helpful Information: Astrophotography page. And don't forget to read the manual, three times, at least.
Thank you very much Mike. I will read the manual a couple of times and follow the steps like you said in your e-mail. Thanks again. Jaz.

Subject: Meade LPI shots for webpage Sent: Wednesday, June 7, 2006 08:08:28 From: email@example.com (firstname.lastname@example.org) Here are 2 highly detailed shots of the moon using my 6" newt, a 2x barlow and the Meade LPI. Both shots are single shots with 0.046 sec. exposure times touched up ever so slightly through Registax. They are of the craters Copernicus and Plato and their surrounding regions. Slowed the scope to F/10 with the barlow (250x) Shot on June 6, 2006 at about 9:30. Thanks for posting and keep up the excellent site. Joe Caggiano
Subject: Jupiter with LPI Sent: Tuesday, June 6, 2006 19:23:33 From: Luis Villa (ETX_125EC_from_arizona@msn.com) These are by far the best pictures I have ever been able to get of Jupiter. Both were taken within minutes of each other on May 27th. The one with the Barlow is a stack of the best 16 out of 50. I used Registrax to stack---- for some reason I seem to be getting better results with Registrax than with the LPI stacks... I think it has to do with the wind on that night, some of the pictures definitely show some blurring due to scope moving--- this is the only night that we really had wind to speak of. I am guessing that LPI tries to stack all of the pictures.... whereas if I choose which ones to stack I get better results. Do you know if this would be the case? The one without the barlow, is one of 54 images, no stacking... this is straight from LPI. I am going to stack the best of the 54 to see what happens. And I will try to resize using Paint Shop Pro, I am hoping for a larger image. Exceptional viewing that night from my backyard. This is the first one I took--- NO barlow--- Now with a 2X barlow---Mike here: I don't think the Autostar Suite software throws out any images that would deteriorate the image. Doing the manual selection process allows you to make the judgement calls on image quality and only include the best images.
Subject: LPI Processing Sent: Friday, June 2, 2006 08:16:47 From: Steve & Carey Young (email@example.com) Is there any way to get a walk through or the processing of an image in Autostar. I know that there is more information in some of my images. Steve Young 1405 Florida Moss Lane Port Orange, Florida 32128
Subject: Jupiter LPI Photo Sent: Tuesday, May 30, 2006 22:36:09 From: firstname.lastname@example.org (email@example.com) Hope your trip to Oracle went well. I have not been able to get out my scope for a long time because our normal "May Gray" marine layer clouds have been very persistant. On the evening of May 18th I took a chance and set up my scope, but within a few minutes the clouds rolled in. On the evening of May 19th the sky cleared, so I set up my scope and kept a wary eye on the horizon. I set up the laptop and the LPI and within a few minutes I captured what I believe is the Great Red Spot. Stats for the attached photo are as follows: Meade ETX 125 UHTC Polar aligned, Meade LPI, no Barlow or filters. I still have not installed the LPI update from Meade, so this image was captured using the old version of the LPI program. The base photo of Jupiter is a composite of 75 images stacked by the LPI program, quality threshold set to 70%. Minor contrast and color adjustments made in Adobe Photoshop. This image was cut and pasted over an intentionally ov erexposed shot of Jupiter to capture two bright moons. Hope you find this suitable for posting on your site. Thanks for keeping your web site up to date. I learn something new every time I visit. Sincerely, Brian Miller Spring Valley, CA
Subject: Io Transition Sent: Tuesday, May 30, 2006 17:29:42 From: firstname.lastname@example.org (email@example.com) Here is a REAL shot of a transition of Io in front of Jupiter taken April 30, 2006. The moon can not be seen, only the shadow can. Taken with my 6" Orion, a Meade LPI and a 2x barlow. I have included a picture of a Jupiter Satellite program which predicted the event. Thanks and keep up the excellent site. Joe Caggiano Glenside, Pa.

Subject: Jupiter 05:24:06 Sent: Saturday, May 27, 2006 08:18:24 From: Tom Mordasky (email@example.com) Jupiter will be out in prime time in the southeast all summer. Here is my latest photo attempt. As with my previous Saturn shots this is a composite of a 5 second exposure with my Canon Powershot for the moons and 187 frames with my Meade LPI for the planet. Most note worthy science wise about this image is Jupiter's oblong shape, very obviously not a sphere.
