So, at the simple click of the wrong button, I have just captured an exquisitely well tracked and centred 1200 second image of my focus star - Doh!

On a more positive note, it gave me an opportunity to check out the flatness of the field of view with my larger (APS C) imaging sensor and I have no complaints there: -

Just spent 15 mins advising a newcomer to read your book and how you were a "God" when it came to imaging.

Hope he misses this post :icon_biggrin:

So do I :icon_biggrin:

Captured a 30min sub of the focus star with 200 X 200 subframe on the other night, luckily I went out to check on how the first image for the night looked :grin:

Thank goodness it's not just me then ......

Sometimes you make the wrong photons count. A while ago I lost my guide star when a cloud moved by. I now have a lovely stack of nothingness north of Cassiopeia to show for it.

Great wordplay, Wim! Nothingness north of Cassiopeia could be a film title :icon_biggrin:

I spent a night of imaging 4h 30m of ngc1499 out of focus from my summer built observatory!

As I was new to the software and camera I thought it was the autostreach bloating the stars, and autofocus did complete..... :happy6:

Curious thing that Autosave in Maxim takes over all the camera control settings but not the subframe ?

I'd love to be able to blame MaxIm or indeed CCD Commander for my faux pas but I can't. CCD Commander does not work directly with Cartes du Ciel so if I want to transfer an RA and DEC into the 'Move To' action, I have to align my mount (or a virtual mount if the object is below my current horizon) with the object and then tell CCD Commander to 'Move to' the current location thus locking the coordinates into CCD Commander - it's quicker and easier than it sounds! However, I located my focus star and copied its coordinates to CCD Commander then forgot that I hadn't slewed to my imaging object and copied the same coordinates into the 'Move To' action for the imaging object grrrr - like a good joke, you really needed to be there :icon_biggrin:

I'm currently telling myself that I won't make that mistake again but confidence is not high :BangHead:

Now that is very annoying. There are so many traps to fall into - I blame the weather here in the UK for my sot of mistakes as you practically have to relearn what to do for each session as they are so far apart!

It's like that here in Norway too. The other night had a clear skies forecast for the entire night, but my observatory was blinded by local fog! I guess fog is not clouds, but they could add a warning :(

My favourites are 

1. forget to remove the focus mask

2. Take the cover off the guide scope 

3. The worst,  I hadn't realised i had changed the APT settings on image review from "fit to screen to 1-1  spent nearly 2 hrs mucking about with focus and plate solver because the image on the screen was nothing like a galaxy I was supposed to be imaging.  As Steve says it was one click away to resolve the problem but I hadn't realised I had changed it.  This was at a dark site I visit once or twice a year to use their kit and this was the only clear night that week :blink:.  

Onward and upward hopefully

On a similar note I once discovered that, in Artemis Capture, the use of the sequencer over-rides all the settings from the regular capture window except, ah, the sub frame selector for focusing on one star. Well, it was a nice star, nicely framed in the middle and, since the image was only about 5 pixels by 5 pixels, I felt I didn't really need to bother with flats when it came to stacking the three hour run....

The other night I wondered why PinPoint wouldn't solve the local pointing model images, put it down to them being out of focus and carried on for shorter subs.

It was only later that I realised I hadn't updated the 'scope / CCD setting for the 80mm f/4.4 and ASI 1600 (Yes, I know it's CMOS) so PinPoint thought it was solving the 130mm f/7 and SX694.

Dur.....

We have all been there, buttons and text boxes all get tripled checked here after many similar experiences.

You can check buttons, text boxes, balance, lens covers until you ar blue in the face, and still miss something.

I know, this happens everytme I set up :(

I am really, and I mean REALLY pleased reading this thread in that it is not just me, I once came home from Spain in frustration just to fix my rig convinced that it needed my presence; one tick in a box and all was fixed (need your emoton of head banging here Steve) Obviously other work was done but I ask you!!

 

Regards

OK here is the secret (and an admission of aging!)

I have checklist - both in the Obs for when I need to do stuff there and in my study that I follow without fail.  You only make a mistake once after that it's your own fault for not checking the list.  Seriously though, simple checklist, reduction in almost all problems.  Would recommend everyone has one.  When I set up each night this was a critical, had a laminated version on my outdoor table and just followed the steps.  With full set up I could be up and running in 10 minutes.

 

Of course still prone to the daft errors, at obs the other day and wiped some post imaging dew of the lens, then forgot to clean.  Lost all of last nights data as the dew had just dried as a smear!  Was not happy ........
