Mars Opposition in a 90mm Refractor

Hello, I did a strip sketch of Mars last night in a spare hour or so while the wife was watching "Strictly" on the telly. I used only my own sketches from 27 September to 21 November 2020, so it doesn't pretend to be an accurate chart. I simply constructed it as an extended drawing from my...

Re: Another "Sunspot" - 19th November

Cliff, have a look today if you can. Theres a new larger spot on the limb that looks like it might be showing the Wilson Effect - and more spots mid-disc. Bob

Re: Another "Sunspot" - 19th November

The Sun seems to be waking up Cliff, I counted 6 spots in two group at noon today (22/11), the large single one in your image, a new one foreshortened on the limb just coming into view, and four faint ones on the northern hemisphere in what looked like a group of two twins with a couple of odd littl...

Mars 21 November 2020

Mars observed tonight between 1915 and 1945 UT, with my 90mm Refractor x165 and x227. The central meridian value of Mars at mid-observation time was 116 degrees. This was a difficult observation: conditions were very variable with short intervals of cloud, haze, and clear spells when Mars brightened...

Harpooning the Moon, Brian. I think it's all part of the process of acquisition that will lead to war by 2050. Bob

Uranus in a small telescope

I tried posting this a few days back but the colour tints in my eyepiece sketch failed to show in the posted image; here are the notes without images. I’ve already posted a brightness estimate made with 15x63 binocs for the planet on Jeff Stevens’Uranus thread. On Nov 10 2020 my estimate was vmag 5....

Re: Binocular catastrophes

Well Brian and Jeff it all goes to show that practical astronomy can be, indeed is, a frustrating and bumbling experierierience :D I suppose we try to get more organised and methodical and patient as we get older, but stuff still happens. My favourite trick was to leave my old 10x50s outside. I woul...

Re: The SUN - 12th November

Hello Cliff, good to see an image of the Sun. I counted 4 spots in two groups on the 12th, just as you show them here. Today, 13th, they looked the same at 1045 UT, except for one more tiny ghostly speck of a spot near the large spot at the preceding limb. 60mm refr. f15, by projection.

Re: Uranus 3rd Nov 2020

Speaking of red stars and magnitudes Mike, I notice that 19 Ari is listed as an M-type semi regular red giant star of a similar brightness to Uranus. I wonder if we would notice a colour contrast between 19 ari and Uranus? I compared them in 10x50 and 15x63 binocs last night but, apart from Uranus l...

Re: Uranus 3rd Nov 2020

I located Uranus this evening with binoculars. Actually I used Aries to find it by climbing down from alpha, beta, gamma, to iota and thence via a semi-circlet of 7th mag stars to 19 Ari, then east about 3 degrees to Uranus. I made a brightness estimate with 15x63 binocs using 31 Ari (listed in one ...

A Magnificent Mess of Sunspots

is now well on the solar disc, but there is also a small group more centrally placed. Observed today at 1155 UT by projection with 60mm aperture at f15. Regards Bob

Re: Uranus 3rd Nov 2020

Yeah, get the scope and eyepieces out Jeff. Don't bother about the floaters - we all get 'em as we get older - I have in the right eye too. Use the left eye. Have scope, use scope. Bob
