Meade ETX-105 & Meade LPI question

Postby bena02099 » Tue Feb 21, 2006 4:13 pm

Hi, I am new to this amazing hobby and have an LPI and an ETX-105 but the software that came with the LPI is (for me) difficult to use. Does anyone have experience of this or can advise how best I can get images please. Ideally I'd like to take pics of planets, galaxies and nebulae

Hi AlShah

When you mention the software, are you refering to the GoTo section?
I recently bought a LPI but I don't have a Meade 'scope so that facility is no good for me.
For just getting images using the CCD part of your purchase is simple enough...but practice during the day on distant objects such as chimney pots...it pays dividends. The more you become familiar thro' the day will make life easier on cold dark evenings.
It's just a stab in the dark here (no pun intended!) but dont forget that the CCD has a very short focal length and what ever you can see with say 200x mag through the plossl will be greter through the CCD, I think mine takes it to 300x, and consequently you will only see your observed object on the "live screen" for a very short time. It took me a while to actually get an image to photograph!!
Have fun....post another question if you want more info. and I'll do my best.

Regards.......Tim

Hi Tim, Thanks I'll try that in the day. The s/w is the imaging not the GoTo - I found the planetarium awful to use! - I think I need to understand basics of image stacking etc but have not found any guides to help.

regards.. Al

Image stacking I havn't got into yet but if you use the combine facility on the live screen it does an excellent job and I think combines the best 10 images automatically. I have some excellent shots of the moon using this.....practise!!
The planatarium....can be tricky, the best way round I found was to centre on Orion and work around from there. Click on the "eye" icon at the top centre of the info. bar TWICE and that will get rid of 95% of all the stars and make the constellations easier to see. I sit for ages with the thing on my laptop and it's taken a few weeks to master the thing!!

Regards.......Tim

By the way its a CMOS sensor and a very small one at that, the LPI will do some bright nebulae pictures such as the orion nebulae M42 but when you talk deep sky like the Rosette nebulae and such things like this the LPI will start to let you down as it does not have the light grasp or high gain needed to do such work also tracking can be an issue unless you are auto guiding of which i assume you are not.
I tried the LPI but was rather upset at the very hard to use software and also the very small thumb nail sized images that show a little detail but not enough for my liking.
So now its a Canon EOS 300D much better than some specialist CCD systems and its an all in one system no wires no laptop could not get better.
And the images can be as large as i would like up to 6.3Mpx although i understand the cost issue LPI £120 Canon EOS 300D £450+

I did think about piggy back cameras, I have an Nikon SLR. I do use the auto track on the ETX-105 autostar but I understand I could get snake movement in the give in the motors. So do you mount the Cannon piggy back or direct with an adapter? Do you have any images I can see of M42 to compare please? I'm after colourful images where possible Thanks Al
