Thanks Nick. According to the Beeb, the Hawaiian name for 1I/2017 U1 is pronounced oh MOO-uh MOO-uh.
I’ve just solved the image in Astrometrica. The software also dabbles in photometry: the estimate is 15.1 CV (unfiltered CCD with V mag zeropoint).
Hello,I noticed a clear patch when putting the bin out and got 45 x 5s frames. Here’s an image. It does seem bright! Midpoint 21/11/2017 2015 UT.
Yes, congrats Robin. The galaxy is nicely positioned, so – weather permitting – I’ll try and get some images over the next week for magnitude estimations. David
Thanks Nick. The software looks really useful. I noted there was a long smudge just below as well, so it does make one a bit doubtful! I’ll try to get multiple stacks as you suggest, and then blink them. David
Certainly not a striking image, but I might just have picked up Heinze above the sky background. Please see the FITS here

and give me your opinion. The midpoint of the capture was 050649 UT on 8 Nov 2017.
Quite. Perhaps, Robin, you should reveal to Eric Watkins where in the UK this astro-friendly micro-climate exists. David
Thanks for flagging this Robin. I can’t do spec, but I do have B, G and R CCD filters – so if the object is bright enough for my setup, I’ll take a set of images. David
Hello everyone. I would like to second Martin Lewis’ question / request for this functionality. If it isn’t too much trouble – I don’t know what would be required ‘under the hood’ of the website. David
Image now visible via Rochester SNimages site. Carried out photometry and checked it – magnitude came out brighter than I judged by eye, at 13.6. Would be good to image this target again. Perhaps Thu. David
I’d be happy to submit my image and magnitude estimation (CCD, clear filter). I gather you have to go through VSnet to get your obs on the Rochester site, so I’ve sent a request to be added to the system. I’ve set a median stacking job going on my laptop during my lunchbreak – I can then use the Aperture Photometry Tool on that image to get a more accurate determination of the SN magnitude, using a couple of comparison stars.
I follow your spectroscopy with interest, Robin. I’ve just imaged the SN – the stacked image is on my observing page. Very bright – guesstimate mag 14, when compared with Gaia 1564852608241033472. The SN is clearly visible on individual frames; I will keep lights and darks in case anyone wants them for photometry. Best wishes – David
Nothing is better than ‘space-walk’ viewing of globulars, open clusters and bright nebulae through a long focal length, wide AFOV, eyepiece. I think both the ease of acquiring images nowadays (cost, expertise required) and also of sharing them has led to the perception that visual observing and freezing to death at the telescope is over. I don’t think that is the case, in terms of absolute numbers of people. I just think there are many more different types of activity going on – and it’s all good as far as I am concerned! I do a lot of visual observing, and keep a log, but I don’t broadcast it. (My sketches are terrible; Paul Abel’s are amazing.) David
It does indeed look like a low-lying castle on the right. I confess I was not familiar with the Crusader type, but I’ve now looked it up. Bamburgh is not too far from where I live, and to follow up from Andrew, that image could be north Northumberland on a poor summer day. LOL. David
Watching the BBC News footage from Kentucky, 1925 our time. Clear prominences visible at the 2 30, 4 and 6 o’clock positions on the solar disc.
I would guess this is an attachment to facilitate afocal photography? The two eyepiece clamps are placed differently with respect to the camera screw to allow different set-ups.
