A short time later > I checked your jpg in ASTAP and it ID a few pixels as possibly IC4617 as well ! You might be able to pull a bit more from the orig. ?

Nice result Yes NGC 6207

T CrB brighter tonight(28-29 April) than it has been since early March Mostly I have had it about m10.3 +/-, on a par with BAA comparison HD 143128 @ m10.3 but tonight I have it just shy of BAA comp HD 143256 @ m9.8 Clouds as usual terminated play, before I could decide if this was significant or just a blip ! Worth a look/check anyone with a clear sky and still awake

I am an imaging noob as well (with 60d astromod and a 60d unmod), so this is a genuine attempt to sort things in my own head as much as suggesting things for you to watch out for ! Or to confuse the heck out of us both ! lol! 3x longer -or wider on the lens stops- has implications for the correct exposure of the rest of the *spectrum (the oft quoted 1/3 histogram rule depending on the light pollution) That 75% +/- is relative to the rest so liable to overexpose everything else. If it is 3 stops lower on the camera exp. compensation this is a fudge on the gain of the camera electronics which affects the sensitivity as well as the dynamic range, so depends on your desired target. If you filter out the *rest of the (unwanted) spectrum with a narrow band Ha filter then 3x longer or wider-stops is then sort of ok but not good to chuck it all away in the existing stock filter Very bad for the SNR. I have not checked the prices recently but under £400 will probably be a much smaller size of sensor area than the crop sensor in the 600d. So it "depends again!" on your desired target/scope/lens combo. & on pointing accuracy, ability to find target, need for mosaic etc&etc , , ! My brain cell is starting to hurt

A monster red as well, perhaps enough to burn off the clouds ?! :} Shame about the bright moon. EDIT : bright =FULL ! Where is the earth shadow/eclipse when u need it !

The equator crosses the ecliptic not far south of it so could be a geo or a stray geo run out of station-keeping. But my money is still on asteroid (4024) Ronan

Not at all sure about this, but for what it might be worth ! :- I am just looking at my images from last night of NGC 4216 and was trying to see if I had imaged (4024) Ronan close by. So I tentatively offer that as a possibility, cant explain the shape ! but is in the right place for about 10 or 11pm?? I think I have it a short distance away on the same track at 1 or 2 am. will post images later. PS I say "or" in my timings because I have just discovered that my image time stamps seem to be still on BST ! eeek

A new 4Tb usb drive. DSS has just announced " ,,needs temporarily 121Gb ,, only 22Gb available"

I think a woodcut or a gargoyle would have to be acceptable ?

Clouds ! Yes, I've lost them the sky is all dark with twinkly things in it ! I'm off, behave yourselves while I am gone >>>>

A happy couple of hours spent learning how to drive LibreOfficeCalc and plot pretty graphs therein Nice exponentials.

swmbo and I were discussing that yesterday, We decided (prob cos I said so !!) that it is a failure of the hospital system to implement back-up plans for mission critical events. Lost mail has been a well known problem since the penny black !

John Bortle was writing his visual description for S&T (Feb2001) It has little point in the moisture laden atmosphere of the UK.

I'm surprised that I didnt get a 'removed word' for my effort !

Beetlejuice is easy to remember, and being being a combo of two other common words less of a dyslexical nightmare, To speel the real word needs looking up, copy, paste. plava to avoid an error and chastisement by pedants ! Whereas Beetlejuice is an obvious attempt at humour as is this post ! Anyhows I am neither an Arab nor an ancient Latin so I dont bother with correct possessives and genders neiver.

and say soder when they are solderng their electrical bits

Sorry ! It was the prospect of the results of Mr V encouraging, via 'tube, people to experiment with electrickery that had me in fits of laughter.

Nice one !

What's the use ? = better than Bortle5 gives bragging rights and street cred on sgl reporting worse than B6, you're just looking for sympathy and a shoulder to cry on.

Ursa minor used to be my goto measure until I got a camera and started stacking 1. shoot yourself 2 Quit looking thro the bedroom window and get outside ,,, 5 Be delighted and rush back indoors to you computer and report on sgl 6 Start a business offering hosting 7 Advertise your domain for sale to a monied person on sgl , , oh hang on, I may have got something a bit wrong there !

Yes! Totally agree. However if you have a camera and are curious about all the fuss/expenditure on SQMs (like I was) there is a clever piece of free software called ASTAP that can measure it with two quick snaps More info on request Has anyone mentioned that there is, or was, an app for iOS can do similar

Thanks The difference (down to 2.3e) may be marginal something more to investigate, but I must not get too OCD about this ! If I get another look at the SN when the moon gets out of the way it might be an interesting test because it is fading quite rapidly !

Been talking size and records over here https://stargazerslounge.com/topic/419441-feb-26th-ar3590-is-a-record-breaker-60-as-big-as-the-carrington-event-in-sept-1859-and-the-biggest-this-cycle/ My big unaided eye one was back in 1956 at 2400 and was spoken of as a record breaker then. SpaceWeatherLive is calling this latest one at 1600 60% of the Carrington one. Edit Ooops that links the top, scroll well down !
