ELP's recommendation has worked for me. I achieved focus using an eyepiece in the barlow to start with and then replaced it with the camera. Thanks for all the advice and help guys 🙂 👍

Guys you are great, thanks so much for your advice and guidance, as of right now anything bigger than a pin head with a line through it would be welcome 🤣. I will be trying it with the diagonal as recommended by Elp later today. Cheers

@Bosun21 As per the title of this thread I am still very new to imaging and am threading my way through a huge intake of information as I get to grips with various components and software. On my initial attempt with just the flattener I was not using video so didn't even think about ROI. The SM90 is my only telescope so may not be a great choice for planetary imaging, but thought I would give it a go with the 4x Powermate anyway. I do appreciate your help and advice @Michael8554 I will give that idea a try today and see what I get. Thank You @900SL and @symmetal it sounds as though 80mm may be the way to go will see if that correlates with the wall test. Thank you

Hi Guys, thanks very much for the advice, I also have a 2x barlow so may give that a go instead. I primarily bought the 90 as my first foray into imaging and I have been delighted with the results for Galaxies and Nebulae. I tried Saturn the other night and could just make out the planet sphere with the rings on either side, was hoping that I could do a little better using the Powermate but there you go. @Elp I wasn't going through the diagonal, but will give that a try also just to see whether I can achieve anything that way

I have a SM90 EDT, Adjustable Flattener, Filter Holder, ASI 585 and a 120mini for guiding all on an AM5 mount. I have used this rig for the last 3 months to successfully image a number of Nebula so no problems with Back Focus . Now that the planetrs are back again I thought I would use my 4x (2") Powermate to increase the magnification so that I could image Saturn, Jupiter and Mars. I was advised to remove the flattener and replace it with the Powermate with the Camera directly attached to the Powernate using the 42mm T-ring adapter. However I cannot get focus, I must be doing something wrong or the advice I was given was incorrect, HELP!!!
