As far as matching histograms, there probably are lots of ways to go about it. All I know is that if you decompose into RGB most of the recent images from Mark...
You are, of course, right. Just because the curves match doesn't mean all the pixels have the same values. Uh, sometimes I'm just daft. :) Tim Schuh ...
I have found that the dynamic range of the DSI-C camera is very sensitive to the gain setting in MaxIm DL and that it is *NOT* linear. The best settings are: ...
Hey Tom, Looks like you are having some tracking problems, which are very apparent on M5. The color and exposure looks pretty good. I would try shorter...
Hi folks, I just posted yet another image of M13 I took recently with much better focus. I must admit, the Meade #1209 microfocuser is starting to pay off and...
Hi Stephane: I'm not sure, but the glow might be amp glow. Some uniformly illuminated flats (with the same temperature and exposure time) might help. Hey,...
That is much better than the first ones you posted. That glow could be light leaking around the filter slide. Once temperatures dropped below 80F at night I...
I'm pretty new to this digital imaging game and would like people's opinion on a cheap focusser. My set up is an 8" LX200 classic with an Orion 80ED...
Thanks Brad, Sorry for the confusion, after re-reading my post, it's not very clear. The M5 and other images from 5-28-06 were my second attempts at taking...
My concern would be the added length. The T-thread can go straight to the camera, big plus. The 1.25" nosepiece is acceptable but I would prefer T-thread...
Hello Michael, Back focus won't be a problem with your SCT or ED80. I'm assuming you want it for the SCT. I've had little trouble focusing the ED80. Only...
Kurt, I have a helical from orion that I'm not using. You're welcome to it, if you have any interest. ... From: Kurt Massey To: Deep-Sky-Imager@yahoogroups.com...
I looked this lovely little thing up. If I can managed another 60mm I'll order one otherwise I'm stuck doing fine focusing with a crappy stock R&P focuser....
Wow, I've been working on similar tests myself. Unlike most CCDs the Meade DSI series has user setable gain. The effect of this is not well documented nor...
Hi, I just purchased a DSI Pro and connected it to my Meade ETX-125Pe and im not sure if im doing something wrong, but I pointed it at the moon and the image...
That's what the Gain does, its a multiplier.... and since the AD is limited to 16bits increased gain will give a quicker image, but at less dynamic range....
Hello Carl, You've got it right. I'm sure you've seen the same thing visually when using high magnification. Its called seeing and is caused by air currents....
Hi Tim, My particular camera is the original DSI-C with no filter tray, hence positive this is no light leak. In addition, I used Hylomar on all seating faces...
Welcome to bad seeing conditions ... temperature and humidity pockets in the atmosphere undulating about and diffracting the light in a likewise manner....
Hi, That page doesn't work for me... im in New Zealand I'll give the DSI another go tonight, its ment to be clear. Carl From: Deep-Sky-Imager@yahoogroups.com ...
The chip itself is very small, about 5mm x 4mm. This makes it a pretty high magnification by the time you get everything into focus. On my f/5 6" I have...
Good evening Stephane, I knew you were using a DSI-C. I really did, honest! Uhg, I fear what my brain will be like after the baby is born. I remember what...
Tim, Thanks for the additional explanations on amp glow. Busy, busy man you will be shortly... the baby is coming! The astro stuff might need wait a little...
I'm anticipating that I'll be volunteering for the night-time feedings. That's how I ended up being the morning shift guy I am now. Our son would wake up...
Hi guys I hope you can help. I did the Autosuite upgrade and at first use it was fine. Tonite I had some glitch with windows (?) and can no longer acquire an...
Hi Glenn, I had the exact same problem when I upgraded to AutoStar Suite version 4. I raised 3 seperate tickets with meade and never got a response. I called...
Hi Glenn, I sometimes get that error, when doing other things on the computer whilst Envisage is capturing images. I think it is to do with the speed of the...
