Another one from Wiruna. I've always loved this glob, but missed seeing it through any of the big dobs at the SPSP, so on the last night thought I'd see what the QHY9 could do with a limited number of exposures.
Purists may point out the glare from Antares is showing up weaknesses in my budget imaging train, but I like the effect from the rays that's come out as I processed this one. Suspect I've ended up with more colour and less noise than I deserved for so few frames, but then again, it is a bright one. This exercise creates a new problem though - the majority of my old Messier pics are looking a bit obsolete now. Have posted an earlier effort with the 450D for comparison (taken 6/6/09 with 4 x 2.5 mins subs) ISO 800). Guess I'll have to revisit many of those in my collection until I'm happy.
Thanks for looking...
QHY9/MPCC on the 8" Newt

I agree Rob - I like the drama/power of the image.
Cool as!

You got some lovely star colours going there. The rays from Antares is a nice effect.
Out of interest Antares is an unbelievably large star. There are a few you-tube videos about star and planet sizes. Our sun is something like 93 million miles in diameter. As I recall Antares is 3.2 billion.

Heck - I knew it was big, buts that's outrageous. Must read up more. Thanks Greg.

Sure t'would be better if the ray pattern wasn't there as it covers the subject but it does look quite quirky and interesting all the same.

Wasn't something I was aiming for Mike - its actually right across the image to the left when you stretch it hard too . I've never encountered this before - something to be on the lookout for in the future I guess.
The Sun is aprox 1000.000kms in Diameter and 150 000.000kms(93million miles from Earth
Antares is three hundred million kilometers in Diameter.
No Billions involved
Nice pic's Rob.
Massive improvement on your earlier image, looks like you'll have to go back through the catalog & do them all again.
But that's part of the process of improving our abilities I guess, revisiting old friends.
I too like the stray rays, they converge some way off the field giving a sense of just how huge a fireball Antares is.
A tactic that can often work, (individual stringettes) if you're not a John cleese /Monty python fan that wont make much sense
Looks fine to me, most scopes have some artifacts around bright stars.... Even the expensive ones.
