hi all just trying to balance my c8 edge but have run out on vixen at the back of the scope only got a filter wheel and ccd on the back end just wondered what length vixen you used on your rig thanks

thanks olly,still trying to get the collimation bang on ,would you say my backfocus and focus look ok though,will give it another go tonight.Just looked on astrobin and seems common with the c8 edge on the cigar galaxy size wise

well just moved over from my 400mm scope to my 2032 mm c8 edge which might not help ,do you think my stars are large or is it that im just used to my 400mm scopes images,scope was focused well ,any comments please,its a 300sec lum sub stretched thanks

Hi all just trying to collimate my c8 edge with a 414ex ccd ,but i cant seem to get the image large enough to adjust collimation any advice please ,is it the 414ex is no good with the c8 for this?

this might help?

hi ive just fitted this to my c8 edge hd ,(ZWO EAF Bracket for Celestron C8 and C9.25 SCTs was the description) straight on no problems and works fine,only problem was i had to alter my imaging train and remove my rotator as it would not fit space wise, hope this helps ,

thanks alan

Hi after a nightmare with dew was looking at these for my c8 edge anyone using one on there c8 edge and have any comments please,and does anyone know the length it sticks out beyond the scope thanks

hi all going back to the beginning a bit ,but what size eyepiece is suitable to do collimation on my c8 edge smallest i have is 13mm but not had the opportunity to try it yet

no probs thanks anyway

thanks thats great👍

thanks not checked collimation will do tonight if possible,presume i leave the 3 locking bolts loose? i can use the image through my ccd to check collimation? thanks again

Hi all well after using my ts optics scope for 2 years ive decided to set my c8 up for imaging,imaging train set to the recommended 133.3mm backfocus ,and guiding was very good anyway a couple of questions someone may be able to help with 1..added a 5 min lum sub stretched ,stars are not perfect any advice 2..the c8 is f10 against my ts optics which was f4 i believe what equivalent time do i need with the c8 for the same capture as the ts optics thanks

Hi all just about to order a baader clicklock for the back of my c8 edge,but are these good enough to hang my imaging train from ,any comments cheers

hi all just trying to set my c8 up for imaging ,removed bits off my other scope and left with needing to fit the bits together need to attached the off axis guider to the rotator ((48mm each side)needs to be about 20mm long to get the oag in) then from the rotator to the c8 which is a 2" male thread i believe,could i use a baader clicklock on the telescope end with a nosepiece to allow small adjustments to my back focus or any other suggestions please

Thanks did it work OK on autofocus

hi all just wondered what your thoughts were on the 2 focusers for the c8

well my best shot

Hi all need a lot of advice please added screenshot of the leo triplet but is discoloured,so far ive used weighted batchpreprocessing with darks flats bias then dbe then done a rgb combination but the resulting image is discoloured ,i know ive took a shortcut but what would you do next thanks https://www.dropbox.com/s/e3g3c12jfpqg8x2/Screenshot 2021-04-08 14.58.27.png?dl=0

hi all just looking at turning my c8 into an imaging set up,hopefully i can use my set up of my ts optics rig ie 414ex ,rotator,oag,filter wheel,but apart from the moonlite (which is well out of my league at the minute) what electronic focusers do i have option of,any advice really appreciated cheers
