Hi, I have read that deconvolution can improve the sharpness of images, however I wish to know what it means exactly. And how is it applied to images. I have a...
Happy New Year Alan. I noted your comment on working with 20 to 30 second exposures. I thought the limit was closer to 10 seconds. Terry - W6LMJ Terrence R....
Hi Terry, The limit on exposure time in alt-az mode before field rotation becomes significant varies tremendously according to where the 'scope is pointing. It...
Hello all, At the moment I am thinking about purchasing a Meade DSI Pro III camera. My main focus for this camera would be to do deep-sky galaxy hunting. At ...
Hi Florentijn. While there are many on this site who are more qualified to answer your questions, since I went from the pro II to the Pro III, I'll give it a...
Florentijn, One item to consider is that the DSI Pro III allows binning, which will increase the sensitivity beyond that which is available with the DSI Pro...
... I find that the larger field of view makes it a lot easier to find targets and keep them in the field of view. The mount I use is a Meade LXD75, I don't...

Hi, Leonard- The HAIP has a typically good explanation without math but here's a shot off the cuff: The image you are working with represents the "true" image...
Alan: You need a repeatable setup that can be replicated time and again. This will decrease your polar alignment time and increase your imaging time. I had the...
Alan, Get yourself a good right angle finder scope and take the time to do a good alignment with your imaging telescope. Then do a Kochab clock alignment or ...
Hi Leonard, and Happy New Year. One of the best treatises on Deconvolution that I have read was in the "Handbook of Astronomical Image Processing" (HAIP) that...
Why would it reduce the FOV? The chip still has the same physical size, so only the resolution should drop to 50% of its unbinned value. Daryl ... Daryl...
It dosnt reduce the FOV just the image size. The FOV is the wether its binned or unbinned Mark ... -- M.T.S.O. http://Astronomy.Qteaser.com N 44° 35' 03" W...
The FOV is the angular view of the sky covered on the chip and that depends only on the optical path in front of the camera. Yes, the file size will be ...

Good evening and Happy New Year. This group has many experts and I am praying that someone lives in DFW??? I would like to see if anyone in this area would be...
Hi Grady, Flats are not subtracted. They are divided pixel by pixel. Typical flat fields have pixel values varying right around 1.0. So dividing a perfect flat...
Gene Thanks but that is not exaclty what I an looking for. The reducer comes with the the adapter and two spacers. Each spacer gave a different focal length....
