First light with baader uhc filter on un modded 1100D

[toxic]

it is worth getting the uhc filter for an un modified eos 1100D, i took these last night with my new baader uhc-s lbooster filter 

5 minut iso 800  with baader uhc-s filter   5 minut iso 400 with sky watcher lp filter 

and then took 3 x 300 second subs no darks flats or bias lifes and got this before the sky got lighter 

i am well chuffed with this filter and not bad for an un modified canon eos 1100D  .

Could you please explain this better? I am confused as to which of these is with or without or...

Does look good, do you have white LEDs lights or are still with the sodium orange glow?

hi leveye top left is with the baader uhc-s l booster filter - top right is the skywatcher lp filter - bottom is the baader uhc-s l booster filter.

could not give a different M27 with skywatcher lp filter as it was taken with 400d so they would not be a true comparison. hope this helps to explain it.

hi happy-kat i have 3 tipe's of street lights around my garden yellow sodium-white mercury and led.

i looked through the scope with the uhc filter on at the yellow sodium street lights and all you could see was a dim orange bulb the LED lights are not a problem and the white mercury was cut by at least half.

so now i am not stuck at 5 to 8 minute exposures, ill have to do a test to find out how long i can expose for before it gets white out.

sorry im like a kid with a new toy

Hi,

I have used this filter  ( in conjunction with a Baader IR block filter ) on quite a few DSO targets including galaxies and have found it to be excellent both as a broadband LP filter and also an Ha enhancer. The only caveat is the light loss that is excess of 1 3/4 stops  so a longer exposure is necessary, somewhere in the region of 600~900s per sub @ F6  if the guiding and the sky background conditions  allow it. The SW LP filter works very well on Galaxies with an IR block filter.

Regrads,
