M42 from 04th Feb was created by TrevorDurity

Despite the almost full moon I tried this out. The IDAS LPS-P1 seems to do a good job. Pity my guiding was off (had to guide Dec by hand); notice the almost ghost images of the stars. Must work on that.

Sac10 + Celestron f6.3 FR + IDAS LPS-P1 + Megrez 90FD APO

4x180 sec + 1x240
10x10sec for Trapezium.

All processing in Photoshop + the red channel upped a tiny bit to make it prettier :wink:

Finally starting to get the hang of this Sac 10.

Now it's off to see if I can get the M81/82 image processed.

Cheers,

Trev

Still a very nice image Trevor. The nebulosity is fab, even though it doesn't appear as bright as I would have thought necessary in order to capture it. Very little hint, if any, in the trailing you mentioned. Is the IDAS LPS-P1 the camera you use?

Cheers guys. Was £$*%()£ cold out there last night. The missus' hairdryer was in constant use :wink:

Seanie, the IDAS LPS-P1 is a Hutech light pollution filter. From what I understand it does a similar job to UHC but is optimised for imaging, in that it keeps as realistic a colour balance as possible. I know a couple of others on the board use these so they would know more about it. I could only find out information about the P2 and P3 versions but I'm assuming this is similar.

Great value in 1.25" version but ferociously expensive in bigger sizes.

The camera used was a Sac 10

Great value camera.

Lovely image Trevor, don't worry about the tracking, it'll come with time.

One thing, is it my imagination or is the nebula mirror imaged, it seems to be pointing the wrong way to me.
You did a good job balancing the centre of the nebula and the surroundings.

Is this IDAS PS1 similar to the one used with cameras like the 300D ?

Sorry Dave, just saw your question.
I believe it's the exact same filter, just an earlier version (P1 rather than P2 - don't know the difference). For the Canon it's the filter that goes between the bayonet and the lens in some kind of custom holder.

It's frequency curve is here:
