Subject: Moon with LPI Sent: Sunday, November 25, 2007 10:39:36 From: Maurice Collins (email@example.com) I had a go at imaging the Moon with a Meade LPI imager and here are my first results. I also imaged Jupiter the week before and captured the bands and satellites faintly. The telescope was my ETX-90/RA, seeing was A-II and time was 0800UT on Moon shots. Jupiter seeing was about A-III and time would have been around 0830UT. Regards, Maurice Collins Palmerston North, NZ.
Subject: Mars on November 7, 2007 Sent: Wednesday, November 14, 2007 12:57:38 From: firstname.lastname@example.org how's it going? Hope you are having better skies than I am. Here's my latest of Mars taken November 7, 2007 with a 10" dob, the Meade LPI and a 5x APO Barlow. Total magnification is around 600x (?). I believe this is the Acidilia Hemisphere. At the time of this picture, Mars was 12.77 arcseconds diameter, -0.76 magnitude and was 0.75 AU's distant (just under 70 million miles). I also snapped a pic of comet 17P / Holmes but the LPI's forte is NOT comets, so, it's not that great. Clear skies and thanks for posting. Joe
Subject: LPI imaging Sent: Sunday, October 21, 2007 13:31:03 From: mike (email@example.com) My name is also Mike and I have the etx 90pe and 80bb scopes with the lpi imager and I am trying to image the orion nebula. i am starting to hav some success. the colors are off a bit but it seems like i may not me exposing long enough. Also if i use a 3.3 or 5 focal reducer on my 80 bb is that just dumb or is that really fast exposure times. here is a link to my pics http://s105.photobucket.com/albums/m232/greaper51/ Thanks MikeMike here: You are on the right track; either increase the individual frame exposure time OR increase the number of images used to "stack". Sometimes hundreds of individual exposures are required. As to a focal reducer on the ETX-80, I don't think you will gain much and I don't know if one will focus properly on the ETX-80.
Thank you for your comments and ultra speedy response, i hunted around the site a bit for more information, great site i tried enhancing a the edges a bit but it seems to be a lot of noise compared to useful detail, so i will go out and capture some more pics to stack and see what happens. It was polar aligned to roughly, my second attempt. it seemed to have a lot of movement in some frames, idk if it was the scope trying to correct but i had to discard quite a few due to movement issues for 8 sec exposures. i got better results with my 80bb in alt/az mode with 15 sec exposures. Any experience with MaximDL?Mike here: Sorry, no experience with MaximDL (a Windows application).
Subject: m42 my best pic Sent: Tuesday, October 23, 2007 10:59:32 Here is a picture of M42 that was captured using etx 80bb and the LPI. next picture I will use the de-rotation feature with meade's envasage to get rid of the star trails. This picture is approx 30min worth of 15 sec exposures stacked in FITS format and combined in MaximDL. Then converted to jpeg with auto stretch.
Subject: Mars, Uranus and More... Sent: Wednesday, October 17, 2007 08:18:16 From: firstname.lastname@example.org (email@example.com) Here are some of my latest pics with the LPI. I got rid of my 6" scope since my last posting and upgraded to a 10" dob. Currently I am still fighting trying to get a decent image out of my Meade DSI. Hopefully I will figure it out soon. Anyway, here are some planetary shots. The first is Mars taken on the morning of October 7. It measured just over 10.1 arcseconds. Taken with (2) barlows in combination (a 2x and a 1.9x) for a total of F/17.9 through a 10" scope. Uranus is "ultra" processed through Registax to bring out (what I believe to be) Titania, Uranus' largest moon. It is just under 900 miles in diameter and glows feebly at magnitude 13.73. There appear to be 2 other moons even dimmer but I can not be certain if they are satellites or not. Uranus currently measures 3.7 arcseconds and is 19.28 AU distance. As always, I needed to send my latest of Jupiter. Taken late summer of this year shortly after I got the new scope. The detail would have been better if one of the equatorial belts didn't fade away. Unguided and non-motorized too.
Subject: Moon Shot w/LPI and ETX 80 Sent: Saturday, September 22, 2007 16:50:15 From: Renee Ann Wirick (firstname.lastname@example.org) Picked up a used LPI at the star party last weekend for cheap and brought it home praying it worked, and I am very impressed, I would highly recommend it in addition the DSI which does not do well for me with the moon or planets. This is my very first attempt and I was impressed, the whole moon fit in the frame, and I added a bit more sky in Photoshop to make it nice. 50 images hand stacked in Photoshop. Thanks as Always for your site, Rene Wirick Thetford, Norfolk, UK
