Thanks both, super helpful and definitely confirmed what I originally thought. I don't have that much to play with in terms of mm adjustment, I'm adding a good few cm from where it's usually focused. I'm a bit short on these sorts of adapter bits and pieces haha. I think to Woldsman's point, the Celestron adapter can be knocked off entirely. Something in this sort of vein (I think) slots straight into the 1.25 to 2, removing a good 3-4cm from the train. https://www.ebay.co.uk/itm/313079134159?chn=ps&_ul=GB&_trkparms=ispr%3D1&amdata=enc%3A1gusBRbbUSuyKRR5DawI74A53&norover=1&mkevt=1&mkrid=710-134428-41853-0&mkcid=2&mkscid=101&itemid=313079134159&targetid=1647205088280&device=c&mktype=pla&googleloc=9045888&poi=&campaignid=17206177401&mkgroupid=136851690655&rlsatarget=pla-1647205088280&abcId=9300866&merchantid=137597110&gad_source=1&gclid=CjwKCAjwh4-wBhB3EiwAeJsppHXkI0oCw1jhJVWragnd5W1E7_y0sXrbjXFAChpFbCwc3mnE7BsVExoC_P8QAvD_BwE

T-ring to Celestron 1.25 adapter (which UHC filter screws into), then 1.25 back to 2 adapter.

This is how I normally attach but 1.25 UHC filter adds the complication

HI all, Quick query about attaching a 1.25 inch Baader UHC filter to (f5) newtonian - camera does not achieve focus. It looks to be due to the lack of focus travel, particularly being f=5. Ideally do not want to use a barlow, but if this is the only way to get any sort of result then am happy to give it go. Currently using a 1.25 to 2 and t 1.25 adapter, greatly increasing the distance between the focuser and the camera. Any way of potentially reducing this? Best, GW

Thanks Olly - realised this on posting and will post in a different part of the forum. Will take a look at your suggestions.

Okay all apparently its the 30 inch Schmidt camera at St andrews University - The James Gregory one.

honestly been rummaging around the internet for this one. are there even any? this odesn't include jodrell bank of course. seb xx

Very good indeed. I imaged M51 for the first time yesterday but I have yet to see the final result!

Lovely Rosette nebula bob and Nige. lI've been enjoying a 3-night clear spell in South West Cornwall and have just been imaging Orion through my 55mm lens. Here is the result, but could do with more data.

Here is the image I am trying to process - a horrible unevenly illuminated image. Thanks, Seb

Ugh!... TGVdenoise is annoying me. I have been reading Pixinsights tutorial on it but it really does not seem to bet getting me anywhere. I seem to have the general idea that the edge protection is the most vital, however, I always seem to get blurry, out of focus images when I move either the strength or edge protection drastically high/low. Otherwise, nothing really changes in the image (or does it?!). Thanks. A good thing to do is to check your FOV on this - http://www.skyatnightmagazine.com/field-view-calculator I found it useful when choosing a telescope BTW, I did a quick ABE on this.

Hey Wim, Tried TGVdenoise - and it seemed to work when I zoomed in. Here is the result
