M42
      #6125834 - 10/08/13 08:52 PM Attachment (48 downloads)

This is Nine 1 minute ISO 6400 RAW files stacked with 16 Dark, Flat, and Bias images in DSS. I haven't done masking before so I wasn't able to fix the core. It isn't too terribly blown out though.

I wanted to stack 10 different objects that night so I really couldn't spend that much time on each one. I was pleasantly surprised that this M42 turned out though. My secondary completely fogged up after the 9th image so that is where I stopped.

With some decent skies, good transparency, and a little more time I might be able to finally get a decent image.

The AT8IN was used on the CG-5 unguided with an unmodified camera. 9 minutes of sky time.

Here is what it looks like straight out of DSS for those that don't like the processed look

Very pretty. Amazing what these cameras can do.
Which camera do you use again? Your Panasonic GH3?

The processed one is....too processed, I like the unprocessed one much better, looks a lot like the pic from my Nikon D40.

It is amazing how different these images look depending on what monitor you use. Here is a vastly different image. This image came from the same subs as the one above. However, the processing in D.S.S was different.

Getting the processing right is probably harder than collecting the data. The two images above looked great on my other monitor. I processed the image below on my main monitor. This one is slightly purple or pink because I hadn't figured out D.S.S yet.

An interesting note is that I didn't use a computer at all for these images. This was done simply with the camera, scope, and mount.

With ISO 6400 and a fast scope you can do short 1 minute subs that don't require a drift alignment or guiding. When I am guiding I use a lower ISO and longer subs. However, it is really nice sometimes to be able to just throw the system up in about 15 minutes and start taking images without needing to bother with a computer.

When I have more time to spend on a single object I always have the option to go with guiding though. I like the flexibility that my system gives me without any compromises in image quality.

Last one. How does this one look on your monitors? Is this any better? This is 13 minutes worth of data. I had some star trails in the last 4 subs but they still add something to it with this few number of subs.

Agree with Kevin - last one looks much better - color balance is improved and faint outer nebulosity looks good with a nice "chocolate" color. Your data is nice and sharp, too.

Agree on the last; others blue shifted to varying degrees. Regards

The AT8in is a great scope!!!!! You did a awesome job using the cg5 unguided. I could never get mine to do that. Great job again!!!

I have had a lot of practice with the CG-5 and AT8IN over the last year or so. I think I probably have a couple hundred hours with my equipment so far.

I hope to do a how to video soon that specifically looks at how to get great results without guiding or using a computer at all for that matter. Using the computer and guide scope can definitely get better results. However, every once in a while I favor quantity and good quality over ultimate quality.

Cant wait to see what you come up with. Hell it will def help out alot of people using that mount with that size of a OTA!

A lot of people said I was nuts for putting the AT8IN on the CG-5. Honestly, I have never really considered it to be that big. The 10 inch is a huge scope for sure but the 8 inch really is not that unwieldy.

Balance is everything. You have to get that dead on. For the images above it was actually off. I took my filter wheel off because I was at a dark site. I forgot to re-balance the scope and it made tracking much more difficult.

I have it sorted out now though. Of course we are blessed with weeks of clouds now.

Ok. Last one I promise. Just trying to get the hang of DSS. Is this one better than the rest?

Another step up, IMHO. I like the better blues in this version. Very nice!
