Hi, after perfecting my goto skill's for the past 9 month's on my LX90 I thought I might move on to DSI imaging. My first try was Mars, but without much success as you can see.
I spent a long time trying to get focus right, envisage magic eye was not much help so used hartman mask instead. Also trying to get exposure etc. right took some time. At first I was pleased to get somthing but dissapointed not to get any surface markings.
Am I doing somthing wrong or perhaps it was down to bad seeing??
Perhaps all you experts could give me some advice as I would like to get this right.   Thanks Dave.

I would say it was down to bad seeing.

It looks just like the same results I got using my LX200 and LPI the week before Christmas.

Looks like possibly bad seeing but looks more like over exposure.
Go as low as you can go then brighten it up with the histo settings.
This as jupitor and Saturn need very short exposures.

I've never had much problem with Jupiter and Saturn and was using shorter exposures for Mars.

Awesome pics guys.  What kind of equipment are you using.

Mine were taken using the Meade LPI and a 10" LX200 gps. I used a 2x barlow for the larger Saturn.

I've never had any good images of Mars though.

This is the best I've done, taken two years ago:

The images look great to me. I have been doing lots of research.  I have a SPC900NC that I will purchase an adapter and a IR Blocking filter. I will have to find software too.  I am still getting to know my scope so I will have to enjoy everyone images until I am ready to start.

Teletex,
Google AstroSnap.
This guy writes a program for doing DSI.
Last I looked, he had an older version that you could download for free.
He lists webcams that works on it, and I managed to get it to work on an unlisted Logitech camera.
Not bad SW for free and probably a good way to get started before investing a $200.

Also, i've done this to make my camera fit into the scope.

A old plastic file canister is.....1.25" an fits nicely into the scope EP Holder. If the webcamera fits into the canister, voila, you have an imager. I then cut my canister down to allow for a wider FOV to get the lens further into the scope.

I did this with some success on terrestrial objects to see if I really wanted to go the route of the more expensive DSI. I would have continued with the webcam, and tried on the moon or other obkects, but the webcam doesn't allow for a long exposure.

So, just another thought since you said you would be looking for some software.

I tried Mars on Saturday with a digital camera. I've managed to get some surface features before but my 3 recent attempts were all failures.

To be honest, though, most of my recent Mars attempts have been almost as an afterthought, as I'm writing a book about deep sky viewing, so it's not on the front burner.

Mars is more difficult to view and see than Jupiter and Saturn and Mercury and venus have their own problems.

Philip,

Any chance of posting one of your latest Mars pics so we can have a look at the differences between ccd and digital camera?

Mark,

Do you know if Meade have any future plans for the LPI?.....maybe an LPI II.

Also have you tried imaging planets with the DSI III?...and can we have a look at some pics if you have.

My Mars shots were all taken at the last opposition:

http://s197.photobuc...illipPugh/Mars/

I've only attempted 2 recently (both failed), as I've been concentrating more on the Messier Catalogue for a forthcoming book. My best visual views were at the 2003 opposition but I didn't have a digital camera in those days.

I do a lot of Sun shots when it's clear but I've also been doing more constellation shots so I can show readers how to find the Messier objects.

Looks like you're getting more detail than me Philip.

I didn't get my first telescope until 2004 so I missed the 2003 opposition.

Good luck with the book Philip.

The last opposition 2005-6 was more favourable than this one.

Folks

Do you need an IR filter or IR/UV filter when imaging Mars, Saturn, Jupiter ??

My images always seem to show very little planetery detail.

I'm using a Celestron 9.25 so i should be able to see stuff.

I have the same problem, though using a ETX-125 so a little less.
There is some advice here on filters

This is about as I've got of Saturn. :-\

What are you using to take your images?

The LPI and all the color versions of the DSI have an IR filter.

This one is the best I did this year. The conditions were quite poor during the opposition.
