m27 another example of registax processing

Posted By Larry Citro

hi All,

lots of rain here so there's time to play at the computer. Registax
v3 has gaussian wavelet processing which seems another way to post
process/high pass filter images.

Here's an lrgb of m27 before and after post processing the jpeg file
with the wavelet filters.

before: http://starryforge.com/ForWeb/m27LRGBpp.jpg

after: http://starryforge.com/ForWeb/m27LRGBppreg.jpg

there are 6 levels of processing with multiple parameters to adjust.

Just thought it might be of interest to some.

It is capable of processing jpeg, tiff and fit files.

m81 & m82

Posted By Larry Citro

hi,

It's been cloudy here so here's an old image reprocessed. M81 & m82 taken with a Televue Genesis SDF and a ST8E. LRGB 40:10:10:10 minutes. Processed in MaxinDL ver 4 and PaintshoPro.

and here's m82

Posted By Larry Citro

Hi,

Here's a recently reprocessed image of M82 taken with a Takahashi Mewlon 250 and a ST8E. Processed in MaximDl ver 4 with Hi & low pass filtering and in PaintshopPro with zonal unsahrp masking. A Lrgb image 30:10:10:10 mins.

Veil Nebula

Posted By Larry Citro

hi,

It's finally cleared up so perhaps I can get some new images soon. In the meantime I'm still reprocessing old ones. Here's an image of the eastern veil NGC6995 HaRGB taken with a Televue Genesis at f5 and a st8e. 120:20;20:20 mins exposure. Processed in MaximDL ver 4 ( including pixel value specific hi and low pass filtering ) and PaintshopPro for some zonal unsharpmasking.

ngc 2903

Posted By Larry Citro

hi,

This is a composite image of ngc2903 in Leo. The L was taken with a st10xme (1x1 binning) and a 8" Vixen VC200L at f9 and the RGB was taken with a Mewlon 250 at f8 and a ST8E 2x2 binning. The image reduction, resizing, rgb combine and aligning was done in MaximDL ver 4. The LRGB combine was done in Paintshop pro along with some zonal unsharpmasking. The jpeg LRGB image then was selective pixel value hi and low pass filtered in Maxim ver 4 and this was followed by some gaussian wavelet processing in Registax ver3.

90:20:20:20 minute exposures at 250 feet elevation in mag 5 skies.

m51 Lum full res cropped image

Posted By Larry Citro

Hi,

Here's a cropped full resolution image of m51. Taken with a Vixen VC200L at f9 and a st10xme. 2 hr exposure with 10 min subs.

Processing done in MaximDL ver 4 with some additional unsharpmasking in PaintShopPro.

M1 (L+R)rgb

Posted By Larry Citro

hi all,

About a week ago I imaged m1 with my mewlon250 at f9 and st10xme using a red CS filter 60 minutes with 5 min subs. In the past I had imaged it with a Vixen VC200L at f9 and a st8e, 40 mins with 5 min subs and had some old (poor) color data taken with the Mewlon and st8e 10 min each channel (2x2 binning).

The resizing and aligmnent of the images was done automatically in MaximDL ver4.The combined R+L was deconvolved in CCDSharp ( 2 iterations) The rgb combine and combining of the R and lum frames was also dome in MaximDl. The (R+L)rgb combine was done in PaintshopPro. The final tiff file was selectively high pass filtered and unsharpmasked in MaximDL so only the pixel values of the tiff ranging from 25000 to 65000 were processed.

I still want to get some better color date and more Red data, but here is the result so far.

clear skies,

m65 lum

Posted By Larry Citro

hi,

This is a 2 hour exposure with 10 min subs on a night with average seeing (5-6/10) taken with a Mewlon 250 and a ST10XME. Processed in MaxinDL ver 4 and Paitntshop Pro. I still have to process the color frames. Presented at 2/3 original size with cropping.

Comments appreciated,

m97 redone

Posted By Larry Citro

Hi all,

I haven't posted much recently, observing and promoting amateur
astronomy to the local groups ( kids and seniors ) has sidetracked me.

Here's a redo of m97 with some new color data.

m97 lrgb 60:20:20:20 mins with a Vixen VC200L and ST10XME

m57 redoing the data

Posted By Larry Citro

hi,

A lrgb of m57 with a ST10XME and Takahashi Mewlon 250 at F9. 100:15:15:15 mins, lum 1x1 binning and rgb 2x2 binning.

clear skies,
