I only have a shot of the computer  screen  after stacking the image  from the 14" in dss and the same image after loading  into gimp

I'm using  dss for stacking,  the image  from my redcat are colour when  I put them in gimp for processing but they're black and white when using my 14" using the same camera and settings,  I've got to check  the settings  in gimp but I've never altered anything  in there Inbetween swapping scopes! 

The image was in colour after I stacked them, when I went to edit the stacked image  in gimp it was black and white, I kept the same settings  after I switched scopes  to the redcat  and the images from that were ok, I checked  the settings  in apt and the debayer box is checked.

Hi all I recent  took some images of the orion nebula  with  my  meade 14" and my zwo asi533,  when I uploaded  the image  into gimp the image was black  and white,  so the following  night I used my redcat 51and the resulting image  was in colour, I used the same settings  on both nights, 180 second exposures, gain 100, offset 70, does anyone  know why this could have  happened,  would  it have anything to do with the different  f/ratio of the 2 telescopes. Thanks  in advance. 

Thanks for the reply. Don't know what the guiding error is, I don't get to use the scope much due to cloud cover, so grab few shots  when i can and see how they turn out and make a few adjustments , done a few 10 second subs last night before the clouds rolled in some looked ok others were a bit bloated 

The collimation is ok. My images are out of focus,  I've  locked the mirror up and I'm only using the zero image shift focuser to focus,  my test exposures are 25seconds but when I view my images and zoom in everything is slightly out of focus,  I've been  using vega to focus then I went over to the andromada galaxy took a couple of images when I checked them they were out of focus. 

It's permanently set up in my observatory. 

I'm not using  an eyepiece, I'm using my asi 533 camera and live view in apt to do my focusing. 

Hi everyone. 

I have I meade lx850 14"sct which I have just started  using  for astrophotography,  I use a bahtinov mask to do my focusing when I get the central spikes centred my images are slightly out of focus . Anyone got any ideas how to overcome this issue. 

Thanks

Thanks 

Thanks  I had the exposure  time set at 20 seconds  when I tried imaging beatleguese will try longer exposure when I next get clear skies 

Thanks for the reply.  I didn't  have my reducer attached  at the time.

Thanks for the reply , I was thinking it might be the gains setting but wasn't  sure  will have a go tonight  if the sky stay clear.

Hi , my new zwo 533 has arrived used to have dslr, I imaged the moon last night to check the camera  is working with asicap, moved on to image a few stars I managed to get a faint image of betlegues which I could barely see and couldn't make out any other stars on my laptop,  what adjustments  should  i make in order to be able to see any stars on my laptop. Thanks  in advance .

No I haven't  got  the latest firmware 

Yes my mount is noisey to, my starlock menu  seems to disappear  after I've polar aligned the scope. 

Thanks 

Hi 

I have a meade lx850 with starlock, the scope has been polar aligned , when I go into the utilities menu I am unable  to find the starlock menu, I have heard of others wo have been unable to going it with some  saying its a dodgy starlock data cable so I disconnected the cable then reconnected it turned  on the scope it asked to align scope but I decided to scroll to the utilities menu  and  that's when I found  the  starlock menu, the I realigned the scope parked the scope turned it off then back  on and I couldn't  find the starlock menu  again  this happens twice  anybody  got any ideas.

My first image of the orion nebula and betelgeuse

Thanks , it's nice to hear my images are good  as I've never really  touched a camera  before , I've  always wondered  what that  rubber thing was on my camera strap.

Thanks for the reply. It was the first chance I've  had since September to open the roof  and do the alignment knew I was close to the pleiades but couldn't  tell from the image now I know why, I'm looking  to get a cmos camera  soon but haven't  decided  which one yet, my exposure  times varied between 15 and 20 seconds. As for the image at the top right I don't know what it is.

Thanks

Ok thanks  for the reply.  Will recentre polaris  in the eyepiece again  using the hand controller should i press enter to align it with polaris again or not.

I have a meade lx850 I polar aligned it then skewed to vega centerd  it and alignment  was successful, when I commanded  the scope  to sleep to polaris  it was off by a few degrees in  the finder scope and I had the same  result when I skewed the scope  back to vega. Could  I correct  this error by using the adjustment knobs on the mount. Thanks. 

My second  attempt  at imaging with unmoded dslr and meade 14 " lx850 , polar aligned the scope but it was out slightly  when  slewed the scope back to polaris, but its not far out so I decided  to take  a couple of images of the pleiades  or I thought I did, what are your  thoughts on these images. Any feedback is greatly appreciated
