Period 6 Days Late, Light Bleeding

M45 - Epsilon 180ED (First Light)

This is the first light with the Takahashi Epsilon 180ED. The medium picture is still processing, you only have an initial adjustment of histograms and color saturation. There are a total of 17 shots of 10 minutes with the Canon EOS 350D at ISO 200, no darks or flats, from ASSR Peguera (Barcelona) and the temperature was about 2 ° during the acquisition of the shots


The image has two problems. First, the focus was done manually without the aid of computers, only through the camera's little screen. The focus point was varied between feeds at night, so that the result of the combined image is slightly out of focus. On the other hand, this camera properly prevents the arrival of the rays from the telescope, which has a very short focal ratio of F/2.8, which generates some very annoying gradients can only be effectively corrected by acquiring good flats . This effect also causes a scattering of light in the stars in the bottom of the image, generating 'Spikes' additional that are not part of the secondary mirror spider. Obviously this problem does not occur with CCD cameras.

How Long Does Robaxin Stay In Ur System



Well, a few days ago I decided to make this great picture of Maximo Ruiz a little experiment with wavelets from the raw data.


Unlike proposed by Maxi making basic processing in PixInsight , which shows the decomposition of the image in layers, I have applied over the entire image processing wavelet, but through a mask. This mask is a combination of luminance and a star mask using the following expression in PixelMath:

mask * ~ star_mask

All wavelets settings I have taken completely out of line, before any transfer function halftones. Previously I have neutralized the background using the Background JavaScript Neutralization script written by Oriol Lehmkuhl , which is publicly available at: http://pixinsight.com/forum/viewtopic.php?t=799

Here you can see results obtained in a mouse-over comparison . Please place your mouse cursor on the links below and wait until upload pictures:

http://astrosurf.com/astro35mm/tutorial/ngc253/mouseover_fa.htm

The first wavelet transformation is basically a technique of image restoration, in which I highlighted the small details scale and increased the overall contrast across the galaxy, using only all the luminance parameters.

The second transformation is designed to enhance the image chroma. By increasing the brightness and contrast of small structures of the luminance is almost always a loss of color saturation. In http://pixinsight.com/examples/deconvolution/Gemini-NGC5189/en.html Juan Conejero proposed for enhancement of color saturation more elegant color adjustment using curves. This procedure is a hyperbolic transfer function. And this is precisely what I have done here. This function is usually applied on large-scale components without affecting small, only on those structures represented in the residual layer of wavelet transformation. And of course in a completely linear.

These are the icons of the process used in this example:


To load icons on the platform process Core 1.2 PixInsight do click with right mouse button on the merits of the application and select Load Process Icons ... Finally you have to double click on the icon PixInsight Core process and automatically load the settings in the window ATrousWaveletTransform .

So this is my small contribution.

Objective:
-Use software tools in the editing and digital imaging.
-Apply effects, filters and plugins

Skills: Creativity - Teamwork - Use of EVA (Blogger - Wikispaces)

Activities: Find and post on Blogspot:

1 .- TERMS (Glossary)

Flatten Image: means that all existing layers in a document are merged into a single. It is used to save the image formats that support only one layer, such as JPEG, GIF, etc.

Brightness: lightness or darkness of a color. Measured in percentage, 0% equals black and 100% corresponds to white.

Channel: every image is composed of channels, the number of them depends on the way color image. For example, an RGB image will have a channel for each of

basic colors: a channel for the red (Red), one for green (Green) and one for blue (Blue)

Channels Alfa: addition of color channels are alpha channels, which are used to store selections. In the palette will display a new thumbnail, the white parts indicate the selected area, the black portions indicate the areas not selected. Channel

compound: composite channel is the one that has two or more channels. Channels

color: the different channels has an image and contains information on colors.

Layer: a layer of Photoshop is a resource that simulates a transparent sheet or acetate. In this you can write, paint, insert images, etc without losing its transparency, and can do each of these actions in different layers. Photoshop can handle up to 100 layers. Active layer

: layer is highlighted blue and you will be editable. It is important to always know what the active layer, because many times when making a modification and this effect arises because the active layer is another desired.

background layer: all document will be composed of at least one layer, and this will be the background layer. In documents from more than one layer, bottom layer is the bottom layer, this can not be changed.

Image layer: an image layer is that which contains images and is susceptible to the effects.

text layer: each time you type a text in the document automatically creates a layer. This layer will contain only the written text and not be able to apply any effect. Layers

linked: called linked layer to that layer that displays a small chain. In lazamos layers to make a single layer temporarily with which they are linked. Linked layers undergo the same modifications as the current layer.

Foreground and background color: colors are stored in the palette. In the front is painted, filled, become degraded, etc, with the background color will be filled and cleared areas of the document increases.

pure colors, pure colors call primary colors and their mixtures, are pure and are not made by others.

Contrast: as the contrast value to view a document with purer colors or more muted. One gray is equivalent to minimum contrast and maximum contrast will make the document to pure colors.

Image Format: the image format or the file refers to the data structure in which to save the document, eg JPEG, TIFF, BMP ... Photoshop supports a variety of formats (see format types).

Guides: are lines that only look on screen and not printed. It is a useful tool as it allows you to adjust your selections, selection borders, and tools to these lines. Is a guideline to click on a ruler and drag the pointer to the document.

Illustrator: program similar to Adobe Photoshop as tools, except that Illustrator is a vector. Instant

(take): a snapshot is a snapshot of the image of the moment to be stored in the history palette below the thumbnail first. Puncturing it in desired to undo all changes when the snapshot was taken.

Layer Masks: is used to cover parts of a layer that is not interested in showing. The masked areas are not lost but is hidden behind the mask without deleting. Turning off the mask again be seen. Are useful if you want to blur the edges of an image, for it in the menu layers add a layer mask. With black color is added mask, white mask is removed. Does not work in the background mask.

color modes: each of the models that can represent both an image viewing and printing.

Opacity: option to control the degree of transparency of a layer. This will vary their own visibility and will look like layers that are underneath it.

Quarkxpress: desktop publishing program used for the composition of magazines and books, allowing you to combine text with illustrations.

Rules: Photoshop tool that shows two rules, a left vertical document and a horizontal at the top. This rule is set from general preferences. It is very useful for accurate work, as always indicates the position of the pointer.

Saturation: saturation is a measure of the authenticity of a color is its purity. Represents the amount of gray colors with a pitch. The gray equals 0% and 100% will complete saturation.

Tone: pitch is the property of a color, the color perceived by the eye. Thus it is said that an object has tone red, blue, green, as expressed by the color name.

Vector Paths: are vector lines that can be created for later

modified: outline and fill color. It may take the desired pattern and make selection, obtaining accurate selections. To have vector character can be exported to programs such as Illustrator. 2 .-

How To Design A Boat To Hold Pennies

wavelet transformations of the sky background modeling

From the extraction of the bottom of a deep sky image we can correct the problems non-uniform illumination and color, such as those associated with vignetting. This forms part of own calibration of the image, and ideally should be applied on raw data linear.

PixInsight has two processing modules extraction mechanisms and automatic dynamic background:
  • AutomaticBackgroundExtraction (ABE)
  • DynamicBackgroundExtraction (DBE)

In normal situations ABE get an excellent modeling of the background of the image, while DBE is more flexible and appropriate when faced with more complicated cases, especially when there is much to refine over the procedure, and the user can intervene dynamically over the image.

Depending on the nature of the problem in different lighting and / or color, image correction must be made by subtraction or division. The vignetting for example is a multiplier effect, so the division is more appropriate. On the other hand, light pollution and atmospheric extinction are additive effects, so that should be neutralized by subtracting.

This is a case of vignetting easy to correct with ABE by division. I have used most of the parameters included by default, except under the generation and global decline of samples, thus avoiding some of the boxes are included on the photographed object.

Figure 1 .- Original vignetting

Figure 2 .- Distribution of samples in ABE

Figure 3 .- Extraction Automatic background (pseudo-flat)

Figure 4 .- Correction to ABE by division

DBE is instead appropriate in more complex cases, as this wide-field photography affected by atmospheric extinction and light pollution. In this test uses only the default, which already introduce a significant improvement.


Being able to act dynamically on the image allows the user to manually place the samples on the bottom of the sky and forcing the modeling mechanism in difficult situations, such as gradients themselves Milky Way.

Can You Take Lorazepam And Benadryl

RGB Color Calibration

The color photographs are almost always required if we are to be calibrated a good color balance across the image. Due to the characteristics of the capture devices, either digital or CCD , the answer is usually not uniform throughout the color spectrum. It is therefore necessary to adjust the weight of each RGB channel . And of course this setting must be linear, because otherwise we can not get a perfect color balance throughout the image.

I always performed the color calibration in PixInsight with the processing module ChannelMatch . My argument is based primarily on the statistical values \u200b\u200bof an object which I know their color. This object reference is usually the sky background, which is assumed to be completely neutral, with no color casts.


First visualize raw images helping a linear transfer function display ( ScreenTransferFunction ) and thus easily locate the regions of sky. Then generated from the initial data from a separate image a preview , which usually call ' background. " Reading and histogram representation of the background shows me clearly indicates that the distribution of pixel values \u200b\u200bof each color channel differ greatly.


The idea is to overlap the bells for each channel of the histogram from ChannelMatch modifying linear correction factors. This way I get a correct color balance, since the main peak of the distribution is often a good indicator of one's own sky.


As you can see above, by varying the correction factors, the bells of the histogram of each color channel are perfectly overlapped, thus obtaining a sample of completely neutral background.


finally obtained correction factors (in this case R = 0.85, G = 0.66 and B = 1.0) are applied over the entire image.

Gay Cruising Spots In Northern New Jersey

nonlinear transformation (MTF)

When we get a series of photos from your digital camera or CCD first need to perform a calibration. The calibration process requires proper application darks, bias flats and light sockets on the photographed object, keeping the linear response of the capture device of the camera.

Through a nonlinear transformation of the data after the calibration process can be adapted to make the image more visible to our eyes, as the data is originally represented a small portion of the available dynamic range in the shadows, so that through a device like a monitor can only visually distinguish saturated image pixels.

This nonlinear transformation is basically a transfer function halftone, which lets you change the values \u200b\u200bdepending on brightness of each pixel.

The following figure shows the histogram of input (raw linear data) and output (linear distribution) HistogramTransformation generated from a deep-sky image.

linear distribution

Distribution nonlinear

From non-linear distribution, the information is distributed over the entire dynamic range available , allowing display devices show much more information recorded clearly.

I Wanna See My Cousins Bpobs



I created this blog mainly because I like to process astronomical images. My intention is to introduce some key processing techniques and update the blog with new techniques as they are developed. All this including some practical examples with the results of applying the various processes on the images.

My favorite application for image processing is PixInsight , a modular processing environment specializing in astrophotography. With this software I can have absolute control of every aspect in the treatment of a recorded image through any capture device, while allowing me to also develop creative skills.

I hope this blog will be useful for all the fans who, like astronomy, I enjoy getting your own photographs, both in solar system objects deep sky.

The Flash file animations appear very often in Web pages and multimedia Web sites, and more recently Rich Internet applications d. They are also widely used in Web ads. 3 .-


GIF: Graphics Interchange Format.
is a widely used graphic format on the World Wide Web, both for images to animation. GIF is a format with no loss of quality images with up to 256 colors, limited by a restricted palette of colors to this issue. For this reason, images with more than 256 colors (color depth greater than 8 bit), the image must adapt by reducing their colors, producing the consequent quality loss.
