As far as workmanship, I would go with the SBIG. Some buddies of mine had ordered several Apogees and all had to go back to be repaired. I know that SBIG has...
What are the effects on an image from a dirty primary? I'm talking about an even coat of dust, not globs or streaks. Lowered contrast, reduced detail, both, or...
Scattered light is one possible result. Brighter stars may show up as more diffuse when stretched, rather than a tighter bell curve on the histogram. How much...
I've heard this before that the Apogee's often need repairs, though some think it's a better Astro camera. But, SBIG is said, like you say, to be more ...
Avery, If you can wait for your camera, SBIG has a new line of USB 2 cameras, the STX series on the way. I love SBIG cameras, I have 5, but the 26 second...
Thanks alot, Stu. I'm gonna try to go to SBIG and personally see and have them explain their full line to me. Some have enjoyed the Apogee as a better ...
Hi guys, I am a beginner in CCD astrophotography and so I am still trying to climb the steep learning curve. I have a ST-4000XCM and a SCT 8" mounted in a CGE....
I've used flats taken with my XCM and with good results. I don't subscribe to not being able to use an OCS for flats at all. How I take my flats... First I...
Roth, Yes, more diffuse at the edges when stretched but also a little spikey (in one direction) and slightly out-of-round (not a guiding issue). I know the...

Your missing FLI which has the best built cameras at persent. Also, Top service IMO. I have the Proline with the KAF 9000. It is the 12u version of the KAF...
I agree in all respects. My FLI Proline KAF 9000 is Tops. The new microline is getting some good reviews. It works with big and small chips. The weight and...
Stu has a good point. However, you might want to consider picking up a used SBIG on Astromart. When the time comes, you can always resell it, if desired, and...
Hello all, It's been a busy and hectic year for me, so while I've been imaging, it hasn't been as much as I'd like and I haven't had much chance to process my...
Eric, That's a nice image! You've resolved it into the core; your star colors are nice, and your stars are sharp. Well done. Two things you could do to...
If I shoot 3 hours of luminance of a galaxy (unbinned), how much color exposure do I need (binned 2x2) to make a good LRGB image? Is there a basic rule of...
... Ron recommends the approximately same exposure for each binned color channel as you used for the unbinned luminance channel. In other words, if you have...
Hi Mike, thanks for the feedback. Regarding the flat plug-in, this is the description in the New CCD Astronomy home page: "The One-shot color Flat Maker...

That's not how it works. First, sensitivity is not increased. And the factor is not 4. <G> Binning pixels accomplished one thing: it reduces the read noise for...

This is relevant here because I'm working on a CCD image. I have PS Elements 4. How can I make a negative from a positive image? The thing is, I've done it...

The color data will show noise - color variability. Dim objects, therefore, will not have any color, or vague color. Or the lum data, when correctly processed,...
I was flipping about my web site tonight and came across an old image of Centaurus A I did some time ago. It was taken with the 6" Starfire and my fantastic...
Hi Matt, I am interested in building a lightbox using the EL material as you described. I have a 12.5" 2800FL scope, and a 530mm 4" piggybacked scope. Do you...
