I wanted to share this shot I made last night.  The Helix Nebula.  It is 20 frames 90 seconds each stacked at ISO 3200 through the Meade 6.3 focal reducer and my 8" LX90.

Not bad at all for such short exposures.

Do you use flat frames?

I think if you used a flat frame to calibrate this image it will improve greatly.

If you do not have a program to apply flats but have PS do a google search for synthetic flat frames in photoshop.

It worked well for me in the past when I first started imaging and didnt know a thing about anything.I was self taught and had to learn this all the hard way.

Also if memory serves me Meades Envisage program will allow you to do flats as well there are several free programs that will help you also.

Again nice image...

Thanks guys.  And Mark, this is the kind of info I am looking for.  Any suggestions to get better.  I've just recently started using darks and haven't tried flats yet. They always looked so time consuming.  I will definitely do a search for info on flats.  Thanks again!

Flats are genereally the easiest ones to get.

Very short exposures without over loading the well of the chip and they will even out the light field and eliminate vignetting..

Try to shoot for about 1/3 of the adu count maybe in the 26000 to 28000 range and see how that exposure time works.

You can check out how to use twilight sky flats or using a white board for flats like I still do.

You are definatly progressing so keep up the good work
