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

Will have a go. Thanks

Wow, brilliant image. I'm thinking about the horsehead and definitely will have a go! Have a go at toning down Altinak, it slightly overpowers the image but apart from that well done!

Some amazing images. Still wrapping my head round about how good these are. I still find it awe inspiring that we can take such images from our backgarden with relatively modest scopes Some top space telescopes 25 years ago would have had the same results, if not worse. Imaging in London has been challenging but I've improved with every image I've taken. Here is my latest - Lots of grainy background (still don't know how to get rid of this). 35mins of exposure with no flats, no bias, no darks with a CLS filter. stacked in DSS and processed in Pixinsight. Thanks, Seb

M42 in black & white. I had pulled out the luminance in pixinsight and was interested with what came through. I still much prefer the color version though

Sorry here, I have compressed one but the other is completely unmodified Alacant, yes I will have another go, thanks Pleiades M45.TIF

Living in London really limits me and this is probably the reason - I need to try imaging somewhere else in the Uk!

Nice image! Did you just use the Bresser scope with the camera? Thanks

Hey guys, I have come back to M45, this time without the CLS filter and with RAW files but still no nebula! Even after stacking I cannot find a single trace of dust and gas. This time I used 80 second subs instead of 60 second to get a slightly higher exposure length. I am very confused - Any help would be much appreciated - Thanks Seb Here is the final image -
