Forthimage – Amateur Astronomy from Edinburgh

This website is a sort of observing log and a place where I can post my images and observations. You can find more information about the equipment I use on the About/Equipment page as well as papers I am co-author of.

Having imaged many of the obvious objects I find it more satisfying now to contribute data to various projects.

To give me something to aim for, I have set up pages to get as many Messier and Lunar 100 objects as I can. The Deep Sky page is for objects not in Messier’s catalogue and includes some more recent lists such as the Caldwell and Finest NGC catalogues.

I am currently President and Webmaster of the Astronomical Society of Edinburgh and some of my pictures are displayed on their Flickr page. I also contribute data to the HOYS citizen science project, ExoClock and the BAA Mars section, as well as others.

NGC 752 / C28 Open Cluster

10 November 2021|Caldwell, News, NGC Autumn, Open Cluster|

Looks ordinary but lots of interest in there if you dig a bit deeper – obviously not all associated with the cluster but just in the fov. Includes a fair number of galaxies, spectroscopic binaries, X ray sources, galaxy groups, radio sources, ir sources, stars with high proper motions. The cluster itself contains about 258 stars, mostly low mass in the main sequence or red giant stage. About 1300 ly away and just on the edge of naked eye visibility at mag. 5.7.

NGC 7008 Fetus Nebula

26 October 2021|News, NGC Summer, Planetary Nebula|

A planetary nebula with a diameter of 1 ly and about 200 ly away (Wiki says 2800 but parallax says 15.7mas ~200ly). Another William Herschel discovery. You can see the central star is still quite bright but is now a cooler white dwarf. There’s a nice double star system just top right of the nebula, although I suspect from their parallaxes (2.13 mas and 1.97 mas) it’s not a binary system. The nebula is much closer with a parallax of 15.7 so not associated with the double star.

M33 tri-band

Only a small window available to take this. Narrowband brings out the emission regions and clusters well I think.

Callisto and Ganymede shadow transits

6 October 2021|Jupiter, News|

Poor seeing so not much detail visible on Jupiter so concentrated on the shadow transits. Seeing comes in and out through the session. 13 frames in an animation. Satellite visible is Ganymede. Callisto is much further out and so the Ganymede shadow catches up with that of Callisto.

M31 tri-band test

9 September 2021|Galaxy, M31-60, Narrowband, News|

Test to see if imaging M31 in tri-band is worth it. Yes! Detail in there that I haven’t seen in other images I’ve taken. Planning a 6 pane mosaic of the galaxy.

Sh2-155, C9 Cave Nebula

Horizontal banding sorted. Camera into USB 2 not 3, and not through a USB hub.

IC 1396 Elephant Trunk Nebula

One I often observe for HOYS but purely for imaging this time. Some horizontal banding noise from somewhere – to be resolved.
