Being on a strict budget, seems like you saved quite a bit by spending $173 for an ~800 mount.
I'd call that alone a huge success.

Good luck Andy in the future on you AP. Off to a great start.

Great images Ouro, looks like you have a natural flair for imaging.

Hi Andy,

Those images are super! And, nice catch on the SN. I also liked M64 (you can clearly see its black eye) and M51. M13 is spectacular as well.

thanks guys, I can't wait to see what I can do with a better mount and a dedicated astro ccd. It is fun though, usually I try and it doesn't turn out so hot.

Thanks,
Andy

Latest Saturn............still not where I want to be in terms of clarity, but I'm getting closer. I keep kicking myself for not tweaking the video settings on wxAstrocapture more before I hit record. I also need to invest in an auto-focuser.

900 frames stacked on Reg 6, f/5 1/25s settings on wxAstrocapture. 3X barlow.

Hi Tim,

Looking great !

Your wxAstrocapture settings, despite what you say, are certainly not that far adrift bearing in mind that a lot of data can and is there to be brought out by processing ! (Attached a quick attempt on my part to release some) !

A motorised focuser will certainly help as will a collimation check before starting and a careful initial focus on a fixed star.

Given that the 8SE is not the best platform for imaging, particularly in view of its drive backlash, you and the other guys using this mount, are producing images of stunning quality far beyond those I ever managed with my Nexstar 8i and a Mk.1 Meade DSI !

Best regards,
Tel

Well, I finally got my lazy hinie out to try my first imaging! Used 6SE and Celestron NexImage camera for these captures. I was also testing a few things - such as, which capture software works best? First image is using Craterlet. Thanks to Tel for his help with this little program.

Here is prior to any processing:



From whence cometh the orange cast?

So I went B&W for this:



Focus is *BLEEP* because seeing was about 2/10. The preview image was like watching the moon through flowing water <ech!> Also, it looks like the bright part of the moon got completely washed out.

Comments, criticism and help all would be much appreciated!

Next I used SharpCap. Same orange cast but not quite as bright as I reduced the gain to near zero trying to stop the over exposure of the bright part.



Here it is processed in B&W:



Somewhat better, but I don't think it had anything to do with the capture software. Seeing had settled a bit to maybe 4/10 - still awful. I think whatever improvement this image shows has more to do with the gain being reduced. I might have been able to get away from the brightness by panning Plato off to the left edge. But Plato was my target. As before any suggestions would be welcome.

Thanks for looking,

Stacking was done in RegiStax for these images. I also did one of the Craterlet captures in AVIStack. AVIStack is definitely the easier to use, especially if you set evertything to automatic. I did NOT use the Wavelets in either stacking program. I did the post processing of these in Photoshop. Used Levels, Curves, High Pass filter, and Sharpen. The last image may have been a little over-sharpened. Please, please post your comments, good or bad!

Thanks,

EDIT: Results in both stacking programs were identical as far as I could see.

ANOTHER EDIT: Both images were taken at 10fps. Next time I'll try 15fps. I got about 2000 frames for each and limited them (in RegiStax) to 70% of the best frames.

Hi Art,

Hmm... Don't know why you are not seeing it. Coming through just fine for me.

Hey Skip,

Yes, welcome to the dark side as Art said. I like the last image! Good that you are trying different things - that's how we make progress.

May you post many more images!

Doug

Ahh....

I can see it now - the wind must've changed direction.

Looks a tad over-processed IMHO

Hi Skip,

Who said it was going to be easy ?

Good progress though, my friend !

I've no experience of using a "Neximage" but it does appear to be a lot more sensitive to both Craterlet and SharpCap than my Phillips webcam. Is it a "Nexstar 5" ?

Anyway, keep playing withose sliders, whichever software you decide to use, and keep the image low on exposure with no bright highlights on your LT screen before you hit the capture button.

As to focusing, your "Neximage" might well be sensitive enough to pick up the likes of Vega in Summer and Sirius in Winter. If you can; use these to obtain sharp focus before slewing to the Moon or available planets.

Best regards,
Tel

Well done Skip. Good first images.

Top marks for effort.

Keep at it my friend and I'm sure you'll get there.

Thanks for posting.

Hi Skip,

congrats on your first lunar capture , as Tel said, no one said it would be easy,and i`m sure you were not expecting it to be so.

Looking at your images suggests to me that perhaps a shorter exposure setting would help in cutting down the whited out areas of the moon, i assume you can adjust the exposure slider in craterlet???(sorry its been a long while since i used the software)

Apart from that, the only other thing i would add ,is that the moon and planets are greatly at the mercy of an often turbulent atmosphere, its really bad when the moon is low and your shooting through a thicker layer of atmosphere.(focus will come and go)Therefore i got used to the fact that shooting the moon when it was at a much higher altitude,where the atmosphere was thinner helped a great deal.

One question if i may, does the NexImage ccd your using, have a built in IR blocker filter,???, if not, then i would suggest you screw one to the nosepiece of the imager, this often helps in giving sharper crisper images.

Keep at it Skip, small steps gets you there just the same.

best regards,

Tom.

Nice capture Skip, you did a good job of proccessing. Keep plugging at it and the images will get better.
