Solar Prominence 4/7/2011
This was the first light for my new setup. A 127mm Evostar refractor modified to accept part of my PST. The sky was somewhat hazy and clouds approaching so I was rushing to get at least some success. Focusing could be better too. Anyway, captured a large prominence on the NW limb at 08.46 UT. With more practice, the images should improve.
Solar Prominence on 27/5/10
Used my more recent Imagingsource DMK 21AF04 webcam to capture this large prominence on the limb of the Sun. Decided to try to colourise the sky near the limb for effect. Taken at 1443 UT.
Image of a sunspot group taken at 12.56 UT. Short reaks between clouds. 5 FPS for I minute at an exposure of 1/1000 sec. Processed in registax 4 and final tweak in Photoshop
Sun on 21/4/06
This is a sequence of images of the sun beginning at 09.22UT, then 13.00 UT, 14.50UT and finally 16.20UT. They show the changes in the prominences on the limb. Each was a sequence of 600 frames at 10fps and 1/33sec exposure.
This was a combination of a surface image and one showing the prom. Combination was done on Photoshop.
Taken at 14.22 UT. The East limb has some activity with a few prominences in view. The surface showed very little activity - just a few filaments.
On the left, a prom on the east limb at 11.06UT. By 14.28 it had changed noticably as seen on the right.
Another go at this target. Settings for the prom were the same as below. The surface was imaged using 10fps, Brightness 100%, Gamma 0, Saturation 5%, shutter 1/500, gain 5%. Captured using K3CCDTools and processed in Registax3. In both cases, all 600 frames were stacked. The two images were then superimposed in PS and cropped.
My first attempts at the Sun using my new Coronado PST telescope. Settings were 10fps, brightness 100%, Gamma 0, Saturation 20%, Shutter 1/33 and gain 20%. Had to overexpose the surface to capture the prominence and so I then blacked out the surface in PS. Image captured in K3CCDTools and processed in Registax 3. Camera was in Normal mode. Best 500 of 600 frames stacked.
Both tis and the image below were taken at f20 through the LX200. Camera was in RAW mode. Images taken with Astrosnap and processed with Reistax 3. A notable improvement compared with my fist attemps at webcamming as can be seen at the bottom of this page.
Waited up till 3am on the 28/2/04 hoping for some good seeing but no luck. I captured these two while passing the time. The one on the left was at 01.55 UT and the other at 02.35 UT. The Great Red Spot can be seen to have moved across the disc in that time. Both were at f25, the first was the best 270 of 750 frames and the other was the best 260 from 770 frames. Acquired with K3CCDtools and processed with Registax.
Focusing was fairly precise. The main drawback was the seeing which was only average
I'm getting the hang of this webcam. these two images of Saturn were taken on successive nights of 16th and 17th January 2004. Attached to a Barlow lens and my 250mm LX200 at an effective f30, I took a sequence of frames using K3CCDTools and then processed the images with Registax. The settings for both were: 5fps, Format 352x288, Brightness 100, Gamma 0, Saturation 50, White balance on automatic, Exposure 1/25 and Gain 30 The adjacent image was processed from the best 800 framesof 1200 and the one below was the best 900 frames from 1150. A notable improvement on my previous attempts.
This was my first attempt and is made up of a stack of the best 560 images taken with a Philips TouCam Pro camera at 1/25 sec exposure and at 10 frames per second. Gain was set to zero and brightness to 100%.Taken through my 10" LX200 telescope
