Some testing from this week.

[multiweb]

I barlowed my 90mm APO and got an OAG fitted to see what I could get away with. I used a Baader FFC. Using a corrector on top of the barlow, I was at x4 which was impractical. I found that getting rid of the corrector worked well at high magnification and I didn't need it. So I managed to barlow at x3 (1800mm FL) and fitted the OAG with a Lodestar.
My guiding was still pretty bad. So chonky stars. Potatoes or mushrooms :question:. Take your pick. Been doing wide field for too long and I need to get back into it.

I still managed to get some cool fields with a good image scale and some details. Once I have worked out the mount I'll be ok to do some interesting close ups.

Camera used was QHY9 with a Baader LUM filter. Here's the results with warts and all.

Eta is 4 panels stitched of 10x2min each, calibrated and stacked.
Big one here (http://www.astropic.net/astro/keyhole_LUM_fffi.jpg)with a 1:1 insert of the keyhole. [1.7MB]

Orion is 9x1min. I also grabbed some color I had from a similar shot with newt couple of years ago and tried to blend the new Lum in.

Bigger ones here (http://www.astropic.net/astro/M42_LUM_f.jpg)and color here (http://www.astropic.net/astro/M42x2_ntdf.jpg).

That's it for this week. Better than nothing with the weather :).
Thanks for looking. :thumbsup:

That's pretty damn good Marc!

The optics in the 90mm apo and the barlow must be very good.


Cheers,

Justin.

Thanks Justin.:thumbsup: The FFC is very high quality. The APO is sharp enough. The operator is still a little soft.


Thanks Larry. :thumbsup:

Thanks a lot Leon. :thumbsup:


Thanks David. :thumbsup:

Thanks David. :thumbsup: Too kind. I always wanted to ask you. What was Lemmy like? Did you guys party or what? Broke any TV set lately?;)

The colour one has so much colour and detail in the gaseous clouds, very good.

Photos look good Marc.

Your refractor shows great potential.

Good to see you hitting the longer focal lengths again.

Good luck.

Ross.
