B33 Horsehead in narrowband

By |2019-01-14T16:26:53+00:0014 January 2019|Categories: Dark nebula, Narrowband, Nebula, News, NGC Winter|

First real narrowband image. Strange reflections of the primary, secondary and spider in Ha and OIII images, as well as flats.
Mappings were OHS and HOS. SII didn’t add much to either image but object is strong in Ha and OIII.

NGC 1514 Crystal Ball Nebula

A chance find, discovered on the way to finding comet 46P. Telescope was unbalanced so guiding was poor. Very noisy image so no real details. Would like to do more with this.

NGC 1514 is a planetary nebula that was discovered by William Herschel on November 13, 1790, describing it “A most singular phaenomenon” and forcing him to rethink his ideas on the construction of the heavens. Up until this point Herschel was convinced that all nebulae consisted of masses of stars too remote to resolve, but now here was a single star “surrounded with a faintly luminous atmosphere.” He went on to conclude “Our judgement I may venture to say, will be, that the nebulosity about the star is not of a starry nature”.

It has since been conjectured that the nebula in fact envelops a tightly orbiting double star with a period of up to 10 days. Gas is presumably expanding away from the larger star of the pair.

97.8% Moon – Copernicus, Kepler, Aristarchus and Sinus Iridium

Not much imaging recently because of terrible weather. This was the only chance and the seeing was incredibly bad after a rain storm. The Maria were undulating so much they looked like there really was water in them. Still got something though.

Lots of gradients and stray light from somewhere coming in. Hard to process and as a result have lost the fainter outer arms.

M31 first test of old 10 inch Newt

By |2018-11-06T15:51:38+00:0012 October 2018|Categories: Galaxy, M31-60, News|

First test of the old 10 inch Newtonian I picked up. Focuser and dovetail were a mess, but with some work it could be good. Optically pretty sound though.
