Hey guys

 

Had some nice clear skies last weekend over both nights, and managed to get 11 hrs worth of subs in total over the 2 nights, which is by far the best run i've ever had. So i decided to use the first few hrs (before the moon came up) to shoot M45. Then i switched to the Soul Nebula, which i still have to process, am hoping to get to that this weekend.

 

So this is 16 x 600s with the D5300a and the IDAS-D1 filter. I think my skies are about 20.5 SQM, so pretty good, but i still need to use the filter otherwise i can't expose for very long at all. I really wanted to shoot more subs, but the moon meant it simply wasn't possible. I probably should have excluded about 4 of the subs, perhaps even 6, due to them having a much brighter sky background, but to hell with it, i decided to let APP stack the lot, and when i compared it to a smaller stack i actually couldn't see any deficiencies. I'm really impressed with APP, the 'Quality' setting really does seem to do a very good job of maximising each sub. 

 

So as always, i used 50 Bias, 30 Flats, and with aggressive dithering. Captured in SGP, stacked in APP, and processed in Photoshop. 

 

This was my first RGB image in about a year. Man, i'd forgot just how hard OSC RGB imaging is when not captured at a dark site!

 

The processing really felt like a struggle on this one, so C&C welcome as always guys. smile.gif

Very nice image..!  Did you have any issues using the IDAS-D1 filter and color corrections?

Thanks guys :-)

 

Jim, i've never noticed the D1 filter making colour balancing noticeably harder i have to say. I know some filters (such as the Astronomik CLS) are known to be very harsh, but i haven't found the D1 to be anywhere near so. Of course, i think on this object it probably helped that it is mostly blue, which is usually not a problem for LPF's smile.gif

Very nice image. Lots of nebulosity between "sisters" showing up nicely in your image. Despite being bright, this object is hard to process as I also went after it with a DSLR & no filter and tons of trouble pulling out the nebulosity correctly. Keep up the good work ..... Anil

Thanks Anil smile.gif

 

This was my first go at M45, and you're absolutely right, in many ways the brightness actually makes it harder to process than many dimmer objects. Keeping those big bright stars under control isn't easy, whilst at the same time trying to pull out as much faint nebulosity as possible, and keeping the background from turning to mush! Targets such as this really make me take my hat off to any imagers who solely use Pixinsight in their workflow. I simply could not have processed this without layers! Obviously it's possible, i just can't even begin to fathom it! tongue2.gif

This is a spectacular image.  I've been contemplating upgrading my Canon XS to a 5300 and this pic sure is pushing me!  Nicely done.

Thanks Jason! smile.gif The D5300 is nice because i know i only ever have to use it at ISO 200. At that ISO, the camera is about as efficient as it can be, with maximum DR as well (a big bonus over older Canon models). 

 

Before my D5300, i had a Canon 60D. I really liked it, it had a nice Video Crop mode that allowed it to double up as a Planetary camera, which was awesome. But in all honesty, as soon as i made the change to the D5300, i haven't looked back since. 

I honestly think that that the newer Nikon models that come with a Sony sensor, represent a decent upgrade over older Canon models. I probably wouldn't bother if i had a high-end Canon (which i'd probably just sell and go for an ASI 1600 instead) but for those on a budget, like myself, the likes of the D5300 probably represents the best bang-for-buck cheap camera out there right now.

My son recently bought one for outdoor and just general photography and it is most impressive.  I love the details and star colors in your pic.  Really has me thinking that my spring bonus check is already spent! lol.gif

 

Did you mod yours or did you have it done?

There's no way I would try doing the mod myself. I'm in the UK, so I sent it off to the guys at JTW Astronomy in Amsterdam. Turnaround time was about a week, and total cost was about £175. Very happy with the service I have to say 😀
