I use it for the UV/ IR cut, I+IR642,IR742,807 and a U filter. It's easier than swopping filters and just means refocusing.

Hi folks, This is one of those questions that over the last year, I am still not that sure on the best set up of my imaging train for planetary imaging using a CPC1100. In my train is first the visual back, X2 Barlow (or powermate 2.5), manual 5 filter wheel, ADC and then the ASI290MC camera. So they say the further the ADC is from the sensor the more adjustment it has but do you have the filter wheel in front of the ADC and camera or the ADC then the filter wheel next to the camera?.

Thanks @geoflewis, It's something I am going to try as soon as it stops raining and the clear skies and seeing return!. In fact I have put it in my 2021 diary🤣

Hi there, absolutely love the photograph!. But you have touched on something I have been thinking of for weeks now reference collimation and the effects of the ADC!. I have a CPC1100 which I have a X2 Barlow, ZWO filter wheel, Omegon ADC attached to my ASI290MC. So I am using a colour camera so it's more useful to use the ADC. Lots of people say collimate with all items in the train except the ADC then add the ADC into the train and adjust to correct but I have always thought that the ADC will throw out the collimation. Am I right in my thoughts that possibly leaving the ADC in the train in a neural position and collimating the train and then when it comes to image Mars which I am doing at the moment, adjust on to Mars and focus, adjust the ADC the correct setting but instead of moving the mount re center by using the collimation screws?. I have added a picture of my setup - still new to astrophotography.

Hi there. Until a month or so ago, I had been using my C1100 SCT in just a alt Az set up. I know you don't see many reviews or people using them but I bought a BresserCPCMOS02000KPA deep sky camera. These are just a couple of the images I took earlier this year with just Alt Az so capturing DS images is possible with just the alt az mounting. most the time I keep the image captures down to 17 seconds and capture about 60 images. I found a near new second hand wedge so I have changed how I capture images but you can do it for DS as well as plantary.

Just an update on my Omegon ADC. after doing the test it appeared to be a left hand ADC but as usual the weathers been doing it's best to ruin things but finally just a chance to try it out again on Jupiter with the CPC1100 and ASI290MC and even though I had to use nearly all it's corrective ability, I still managed to get the images attached - not the best by far but seeing the conditions were so bad, I am happy!.

I did find that it is very very small adjustments on the focusing - like you said wait till you get the chance to try it on the moon.

Hi there, I have used this little camera and once you get it set up, it's not bad at capturing the moon etc. Just a quick question - when you have aligned you scope and looked at the object through your eyepiece. Then your removing the eyepiece, putting the camera in and then refocusing the telescope so the camera is now in focus. Is this correct?.

Hi Craig, well just used the test and the correction is better with the levers on the left-hand side so my Omegon ADC must be a left hander!. As you adjust the prisms, the image moves downwards and the definition of the circle edge becomes much more defined. also thinking back, I once attached the camera with the ADC quickly with the levers to the left and when I adjusted it the image got worse BUT I had a diagonal fitted which would have caused this to happen.

Hi Nicolàs and Geoff, thanks for the information. I have been struggling to get the correct set up information - even the information from the manufacture didn't make sense because there information sheet showed the adjustment levers on the right and level with the horizon BUT during the conversation they said to set it up so the levers / neutral mark pointed vertical from the horizon which meant the correction would be in the horizontal and not vertical!.

Hi there, I am new to the forum and have a Omegon ADC and a ASI290 on a CPC1100. The seeing has never been that good when I have used the ADC but which side should the levers be? is it on the left or the right when set up?. If the levers are set up so they are on the left, when adjusted the image moves down which I always thought would be correct because I have always believed that objects always look higher than they are - is this right?
