Too hazy in London it seems

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

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

WHAT is the largest optical telescope in the UK?

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

From the album: Imaging Challenge #15 - The Milky Way - Now Closed
Milky way in B&W in San Lawrenz, Malta - some stunning skies there this summer and the bonus of seeing the lunar eclipse! Canon EOS 60D, roughly about forty thirty second exposures. Stacked using DSS, altered colour with windows pics Taken 9th August. -

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. -

The EQ3 DSO Challenge
Galactic Wanderer replied to Stub Mandrel's topic in Getting Started With Imaging
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. -

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 -

Galactic Wanderer replied to Stub Mandrel's topic in Getting Started With Imaging
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 -
