Hello,

This nebula has many names: Monkey Head Nebula, IC 2159, Sharpless 252, NGC 2175. I found only a few images of this nebula on the web. So I decided to take an image with the Moravian G2-8300 at the 12″ f/4 Newtonian with LRGBHaOIII=90:90:90:90:570:360 minutes which gives a total exposure time of 21.5  hours. Subexposures were 10 minutes for LRGB, 30 minutes for Ha and 60 minutes for OIII.

Under the menu Latest Images you will find the zoomify version, so you can watch all the details of this beautiful nebula.

Hi,

this is a very special theme. I took 6h exposure from the Gulf of Mexico in NGC 7000. The first image is 18x 20 minute subframes. The second image is 3x 120 minutes subframes. So you can compare long time subs and short time subs. Total exposure time is the same. Processing for both images: Calibrate, Align, Data Reject, Median Combine in CCDStack. Histogram Transfer and HDRMultiscale Transform in PixInsight. Topaz Adjust in Photoshop with the same parameters for both images. Neat Image for a little bit of noise reduction.

I think long time has less noise and the very faint details are better. Contrast in brighter regions looks better in short time.

I am very interested in your opinion.

Long time subs

Hello,

I took an image from the Gulf of Mexico in NGC7000 with 7 channels: L R G B Ha OIII Hb. Exposure time was 70 minutes for L, R, G , B with subs of 5 minutes, 820 minutes for Ha, 300 minutes for OIII and Hb with 20 minutes subs.

Especially the line filters gave great color to the image. At the “coast” of the gulf you see a light which I extracted to the small image below. I do not know what this light is. If you know please tell me.

A Zoomify is found in the menu of the new images.

Kind regards

Hello,

I felt the time has come to take a new image of the Cocoon Nebula. So here it is with the Moravian G2-8300 at the 12″ f/4 Newtonian with LRGBHa = 430:100:100:100:290 minutes which gives a total exposure time of 17 hours. Subexposures were 10 minutes. I tried Hb too with 30 minutes subexposures but I did not use them  because they did not really change  the image.

Under the menu New Images you will find the zoomify version, so you can watch all the details of this beautiful nebula.

Hello again,

here is my new version of the Dumbbell nebula M27 in the constellation of vulpecula. This is my second image with 7 channels: L R G B Ha OIII Hb. The total exposure time was 28 hours. LRGBHaOIIIHb = 350:100:100:100:350:350:350 minutes with 10 minutes subexposures.

Hello,

I saw the famous Hubble Deep Field image and I wanted to take an image like this. So I centered my 12″ f/4 Newtonian at IC 3949 and exposed LRGB = 780:95:95:95 minutes. Subexposures were 5 minutes for RGB and 10 minutes for luminance.

Hello,

rain and clouds caused more than 1 month to collect the data for my new image of M101.

Imaged with the Moravian G2-8300 connected to my 12″ f/4 Newtonian
Exposure: LRGB=500:200:200:200 minutes, Subframes 5 minutes
 

A few years I had no opportunity to get M42 on my chip. This winter I got it. And this is my first image I processed with PixInsight. Imaged with my 12″ f/4 Newtonian and the Moravian G2-8300 CCD Camera.
