Hi Milton, 

They`re both great, it`s good you`ve been able to finally do some shooting! 

I`m wondering about whether you think buying the Baader LRGB filters would really be worthwhile for the Scorpion 20SOM I have..? 

Such an expenditure would be some way down the track. 

I`m being attracted to the Astronomics sale on the AT6RC in the next month. It`s only $299 but would be an additional $200 USD postage for me out here in Australia..

I think this might be a real bargain..

I`m also being convinced that the T-point add on for my The Sky X SAE would be a worthwhile expenditure at $249 USD considering my problems locating things at present..

NGC 3372 was rather large & locate-able but NGC 6744 has so far defied me..

Mind you the rain`s returned here so I haven`t re-done my polar alignment..

I`m also looking at upgrading my mount to a CGEM by early next year (to be bought in the US to save lots of money..) The CG-5 could then be used for one of the other telescopes..

Mark.

Thanks Jim and Allan;

I also just posted M15:

Seeing had dropped off by the time I started on it and FWHM is in the more normal (for here anyhow) 5 to 6.5 arc second range.

Even with the LPR filter, my sky background was 9,000 to 10,000 out of 65,535 for 10 minute exposures. It would be about 20,000 to 24,000 without the LPR.

Have a nice weekend..
