Comet C/2020 F3 (NEOWISE)

On July 11th 2020 I drove out to the Keeper's Pond at Blaenavon.

I used an AstroTrack mount, a Canon 50D DSLR camera with a Tamron 18mm to 270mm zoom lens.

The lens was set at f/6.3 with the camera ISO set at 800.

I captured sets of three, two minute exposures which were averaged together to reveal the final results.

NGC6820 - NGC6823

This lies in the constellation of Vulpecula the Fox. I was using an 80mm refractor at f/6.3, a Vixen Atlux mount, PHD autoguiding, an Atik 383L mono CCD camera and a set of Astronomik narrowband filters, SII, OIII and H-alpha.

I captured 2.5 minute sub-frames with the camera set on times 2 binning mode. I then took matching dark-frames and flat field frames. The total exposure times were 30 minutes for OIII, 30 minutes for SII and 80 minutes using the H-alpha filter.

M11

This image of M11 was captured using my 80mm refractor at f/6.3, a Vixen Atlux mount and an Atik 383L mono CCD camera.

I captured 5 minute sub-frames with matching dark-frames and combined them with flat-field frames to reduce the effect of vignetting in the final image,

The total exposure times were 80 minutes using a H-alpha filter, 30 minutes using an OIII filter and 25 minutes using a SII filter.

M57

This image of M57 reveals its location between the two stars Sulafat and Sheliak in the constellation of Lyra. I captured this immage under hazy sky conditions with stars only visible down to magnitude 3. The telescope I was using was an 80mm refractor at f/6.3 mounted on a Vixen Atlux mount. PHD autoguiding was used and an Atik 383L mono CCD camera was used with narrowband filters; SII, OIII, and H-alpha. Total exposure times were 40 minutes for each filter. I captured 5 minute sub-frames with matching dark frames and combined them with flat-fields to reduce the effect of vignetting in the final image.

Imaging M17 with a very narrow window of opportunity

Click on an image to get a closer view.

This image shows the narrow time-slot for imaging M17 between two rooftops. There is a 12 degree window giving me only 40 minutes of imaging time.

M17 rising from the rooftop. In this image the camera was set to times two bin mode to increase the sensitivity. The total exposure time was 60s.

This image was taken using an 80mm refractor, a Vixen Atlux mount and an Atik 383L mono CCD camera. The camera was set to times two bin mode, capturing 60s sub-frames. The total exposure time was 10 minutes for each Red, Green and Blue filter.

This is a bi-colour image of M17 using H-alpha for Red and OIII for Blue. The total exposure times were 20 minutes for each filter, capturing 60s sub-frames.

This is an image of M17 using the Hubble palette, with total exposure times of 20 minutes for each filter, using 60s sub-frames with the camera set on times two bin mode.
