@northernassist Due on 14:23 Lincoln to sheffield

[Derek Foster @DerekFoster]

@LNER can you tell me where the replacement buse stands are from Doncaster Station to Sheffield? Thanks!

[Derek Foster @DerekFoster]

@northernassist Thank you. It ended up taking 3.5 hours for a journey that is 1hr 20m by train. Even with the 30min driver break it was still 3hrs driving time with no heavy traffic. The quoted estimate was 2hrs 10m. Doubt anybody would ever do the journey if they knew it was going to take 3hrs

[Derek Foster @DerekFoster]

@northernassist you may want to review bus route for Sheffield>Lincoln replacement bus. Taken 1hr 15 minutes just to get to Worksop, it was 25 minutes just to get to Darnall (5 mins on train). There was no heavy traffice just incredibly long route. Must be a better route.

[Derek Foster @DerekFoster]

@northernassist It's not working I'm afraid. Been on this bus for nearly 2hr 45m and still not arrived in Lincoln. Driver has now said he cannot continue as run out of driver hours and cannot drive further.That tells you northern have woefully miscalculated journey times.

Christmas Tree Cluster in HOO with RGB stars, around 6 hours of data using @QHYCCD 268m and 115mm triplet #Astrophotography

[Derek Foster @DerekFoster]

@EastMidRailway But it is NOT a priority to get those passengers sitting on the delayed trains for hours and hiurs to the train's actual final destination? So timetables over getting people where they need to be?

[Derek Foster @DerekFoster]

@EastMidRailway You mean we are being thrown out at Chesterfield after all the issues on this service? What a shambles, to top it off your delay repay site is down. Can you guys actually run a train company??

[Derek Foster @DerekFoster]

@EastMidRailway I'm on the delayed 09:30 from St pancras to Sheffield. After all the delays and overcrowdin on this service, are you jokers going to throe us all out at Chesterfield before we get to Sheffield?

[Derek Foster @DerekFoster]

Squid Nebula around 19 hours of HOO data. Taken in Sheffield, UK with @QHYCCD 268M Camera and 115m triplet. #Astrophotography

[Derek Foster @DerekFoster]

First Heart Nebula image as we move into Winter. Took this with the Redcat and @QHYCCD 268m camera, around 7hours of SHO data from Sheffield, UK #astrophotography

Cygnus Constellation in widefield, taking in the Crescent Nebula on middle left and Tulip Nebula on top right. Taken from my back garden using Redcat 51 scope and 268m camera. Around 6 hours of SHO data. #astrophotography

@TonyPeric @QHYCCD For LRGB I need to take super short exposures because of the light pollution where Iive. This is 1499 images integrated. The bulk of the images is comprised of 15 sec subs for Lum, 20 sec subs for RGB, and just x12 300 sec subs for Ha.

[Derek Foster @DerekFoster]

Andromeda Galaxy in Ha+LRGB. 8 hours of data using Redcat 51 scope + @QHYCCD 268m camera. Sheffield, UK. #astrophotography

[Derek Foster @DerekFoster]

This is gunna take a while, 1499 lights to integrate with drizzling and needs a 325GB working space in Pixinsight. Data is for Andromeda in LRGBHa and lots and lots of 15 and 20 sec subs. Hope its worth it! #astro

New laptop with an Intel 258V CPU that has an NPU. No apps seem to use it yet so loaded it with a Deepseek 7B model quantised to 4bit and it did surprisingly ok! About 10 words a second and only using around 4-5GB RAM. Interesting.

[Derek Foster @DerekFoster]

Pacman Nebula in SHO. Recent data from a @QHYCCD 268m and 115mm triplet, around 7 hours. #astrophotography
