A few objects caught last night

[barkingsteve]

evo 925 with F6.3 reducer and 385c camera. I did not use the ir or cls filter last night, still experimenting   from a red/white zone ( i think, 12 miles from central London facing an A road less than 1/2 mile away ) Some light editing in photoshop.

 

M2  66 frames @ 134 seconds

 

M13 40 frames @ 179 seconds

 

M15 42 frames @ 85 seconds

 

M27 64 frames @ 297 seconds

 

M33 30 frames @ 294 seconds

 

M57 19 frames @ 273 seconds

 

M92 24 frames @ 152 seconds

 

NGC 1023 40 frames @ 516 seconds

 

NGC 1245 21 frames @ 264 seconds

 

Still amazes me i can see so much from my crappy location

Nice work. Well done!

Hi barkingsteve,

Nice pictures, I understand that your scope  has an altaz mount. Did you use a wedge? I imagine you would get star trails with exposures like 516 seconds otherwise.

Hi,

   no wedge, that  is total exposure time.  for example when i say 60 frames @ 120 seconds, that is 60 x 2 second frames stacked.

Amazing results, especially for your zone! Love the Ring and the globs are stellar!

Very nice results in colour. Have you tried using a more aggressive reducer like 0.5 or 0.33? I think this would definitely help on the fainter stuff like M33. The 0.33 reducers can be a challenge; I can’t get any faster than 0.45 without coma like effects but this still halves the exposure times needed compared to 0.63. If you could get down to 0.33 (which plenty of people seem to do) then the exposures times are a quarter compared to 0.63. Your sensor size is similar to my small lodestar camera, so should work for more aggressive focal reduction I think.
