m3 lrgb

Posted By Larry Citro
hi,

A image of m3 taken with my Takahashi Mewlon 250 at f12,ST8-E 2x2bin LRGB 3:2:2:2 min "snapshot"

Given the short lenght of the exposures I was surprised how it came out...I had to do a little noise filtering in paintshop Pro

m101 wide field lrgb image

Posted By Larry Citro
hi all,

had a few clear nights so I got some images done. On this evening I was using my mak-newt visual and imaging with the Genesis. I started early when m101 was to my NE which resulted in multi-gradients ...curse of urban light pollution. Later when it was to the NW it's full extent was eaisly seen in the 6" mak at 30x .. my limiting mag in that direction is about 5.5.

LRGB image 90:15:15:15 minutes with a ST8-E and the Genesis at F5.

clear skies,

m106 LRGB

Posted By Larry Citro
Hi All,

I took this image with the first "big" scope I ever had... a Celestron 8 sct I bought in 1977. I was a windy night with some gusts to 20+ mph and as a result 1/2 of the images were ruined.

Its a LRGB 60:15:15:15 mins taken with ST8-E 1x1 bin L and 2x2 bin RGB. The L and RGB were processed in MaximDL and loaded into paitshopPro as 16 bit TIFF images and combined there.

hi,

I added some lum to the image from a older shot and reworked the colors a bit. Taken with a C8 at f10 and a ST8-E camera 2x2 binning LRGB 90:15:15:15 minutes.

M 101 lrgb image

Posted By Larry Citro
Hi all,

Lrgb image of m101 taken with televue genesis sdf and a ST8-E 60:15:15:15 minutes. There are some gradients from light pollution I've had a very hard time dealing with ..this is the best so far.

Gassendi near and far

Hi all,

wide field taken with a 35mm eyepiece and no zooom ..Gassendi is marked with a cross

a shot taken with a 8 mm eyepiece and 3x zoom showing Gassendi,the Mare Humorum and the carters Diophantus and Lee.

a shot taken with a 5mm eyepiece and 3x zoom of Gassendi.


Taken in very good but not the best seeing (7/10)

m81&81 RRGB ( a mistake)

Posted By Larry Citro
hi all,

This ia a RRGB of m81&82. RRGB 60:10:10:10 mins with a Televue Genesis SDF @ f5. The 60 mins of R was a mistake ( i thought the clear filter was active )

Anyway it didn't come out too bad .. some nosie and some gradients are present.

ngc3623

Posted By Larry Citro
hi all,

here's an image of ngc 3623, part of the Leo TRIO. Taken with an orange tube (old) C-8, and a ST8-E camera. LRGB 70:10:10:10 minutes (L 1x1 bin RGB 2x2 bin . L and RGB processed in MaximDL and 8 bit jpegs were LRGB combined in PaintshopPro. The moon was out so some wicked gradients resulted in the raw images ... I did the best I could to remove them ...but if you look they still there.

The raw FWHM of the images was 2.4 arcsec and after 3 iterations of ccdshararp it came down to 1.9 arcsec.

clear skies,
