iapa Posted June 2, 2016 Share Posted June 2, 2016 8 images, of 100, barely useably from last night from 00:30 - 02:35. Massive vignetting. ISO1600, 90sec, unguided. Moral: Don't waste your time at this time of year as the Sun is still too bright. GET FLATS What is your worst ? Link to comment Share on other sites More sharing options...

scross86 Posted June 3, 2016 Share Posted June 3, 2016 Can always get worse that that... at least there is fuzz :P. Agreed that the sun is making it a bit hard for total darkness shots. Link to comment Share on other sites More sharing options...
Astroscot2 Posted June 3, 2016 Share Posted June 3, 2016 At least your making the best of the good weather. I stop imaging from this latitude mid April and restart at the end of July, The sky is far to bright to do any worthwhile broadband imaging.

Stub Mandrel Posted June 3, 2016 Share Posted June 3, 2016 I was disappointed by this one, after seeing how gloriously it comes out in everyoin else's pics! Link to comment Share on other sites More sharing options...

calli Posted June 3, 2016 Share Posted June 3, 2016 (edited) My worst and best (because I was only one time able to capture...). AND I was happy! I did not expect any structure but only two blobs. Mak127 on NexStar SLT Goto, Nikon D3100. I think I used 20 subs, darks maybe. Too long ago. DSS had (obviously) not enough stars, so I manually registered in PI (which I evaluated that time).

iapa Posted June 3, 2016 Author Share Posted June 3, 2016 Everyone - can you also note equipment, ISO, exposure etc for your images. Someone with a £10K mount, 30K worth of optics, liquid nitrogen cooled CCD etc , getting the same poor crap as mine - deserves 'worst image in the world'.

gnomus Posted June 3, 2016 Share Posted June 3, 2016 22 hours ago, iapa said: What is your worst ? Very disappointing iapa. It is still recognizably M51. Plus, the focussing and tracking look OK. No, no. If you are aiming for 'art' I offer you ... M31 This masterpiece was created in Nov 2014. Notice how I have composed the image such that the galaxy is framed in a slightly 'disorientating' manner. Clearly, the artist is drawing attention to our place in the universe and the slightly unsettling feeling one gets when contemplating such matters. To emphasise this concept, I have chosen to have M31 'out of focus' (if you get my drift) and with imprecise tracking - achieved by very precise polar misalignment. The processing has been carried out in such a manner as to leave it nearly devoid of colour - these are binary, if you will, black-and-white concepts that we are dealing with here. Yet there is that muddy brown patch bottom left - I will leave you to figure out the meaning of that for yourself. Final flourishes include careful bloating of the mis-shapen stars. This is, perhaps, the only thing I would change - way too obvious, don't you think? Steve 4 Link to comment Share on other sites More sharing options...
Demonperformer Posted June 3, 2016 Share Posted June 3, 2016 In an effort to get this thread back on topic (most of the pictures posted are far too good to qualify as "worst" pictures ) ... I have chosen for my example (one from a vast collection) a picture taken on the evening of 4th June, 2013, using my 102SCT + Canon 1000d, just above "streetlight alley". 27/96x 20 second exposures stacked, stretched and curved. Clearly, the target is M83. For those of you who don't believe me, maybe a little orientation will help you check it on CdC/stellarium: The bright star towards the upper left corner is HD 118646. The slightly fainter star below it is HD 118600. The line of three faint stars at roughly the 10-4 position from this star are (from left to right) UCAC4-301-073462. UCAC4-301-074345 & UCAC4-301-073399. [Don't be fooled by the much brighter line of three stars below them in an almost vertical row.] Perpendicular to this line of stars, above the middle star, at roughly the same distance from this middle star as it is from each of the other two in the line, is another faint dot. This is the centre of M83. When it comes to taking pictures of inferior quality, that were a complete waste of effort, you should all kneel before your master! 3 Link to comment Share on other sites More sharing options...
iapa Posted June 3, 2016 Author Share Posted June 3, 2016 (edited) @Demonperformer now we are talking LOL @gnomus explanation seems a it too contrived - way more effort in that than the image. Edited June 3, 2016 by iapa Link to comment Share on other sites More sharing options...
michael8554 Posted June 4, 2016 Share Posted June 4, 2016 Demonperformer, I've been thinking of reprocessing some of my images using the "Darks for Lights" technique, thanks for posting your definitive image. Michael Link to comment Share on other sites More sharing options...

Any target - as long as reasonable effort was taken to obtain the lights, and the result is particularly horrendous Re image - are you sure that was your target? Looks like a street light and fireflies Possibly a better example of less that satisfying results than my attempt... I'll let other do the judging LOL 1 Link to comment Share on other sites More sharing options...
