M65 & NGC2264 but necessarily in the same image!

I started imaging the Cone Nebula on 7th March, but only managed a couple of hours due to it's position in the sky and trees. Then I got another couple of hours in HOO on the 15th March, giving a total of 4h15m using Baader 3.5nm Ha & 4.0nm Oiii filters on the ASi1600MM Pro at -10°. I will add more data, including Sii, if I get the chance, but thought I would process what I have.

After the Cone Nebula started to get into the trees, I swapped completely and went for the Leo Triplets using LRGB. This was only 1h28m with most of that being luminance and only 16 minutes each on the RGB filters. I wanted to do more but I needed sleep. Overall, it hasn't come out too bad for such a short integration and I can add more data later. 

Both of these were taken using the Skywatcher Evostar 100ED DS Pro with 0.85 FR/FF, on a belt driven HEQ5.

The Nebula really comes out nice, even though you have used a scope at f/7.6, the 100ED Doublet so under rated for DSO Imaging. You have encouraged me to invest in a reducer for my C100ED,

Nice images. Love the Leo Triplet. I really need to go back to it with my 6" F/5 Schmidt-Newton and gather more data (but then of course, the weather has to play ball first).

Cheers

The Ha is quite strong but I was a little disappointed the Oiii in the centre of the Christmas Tree Cluster isn’t more pronounced.

 I do like my 100ED, as you say, it’s not the fastest scope but does deliver some good results. It’s my go to for galaxy season but also gets some nice detail from nebulas as well.

Is it OIII or blue reflection?

Good question, I assumed it was Oiii in there as I imaged the nebula back in 2022 with the Askar Duo-band filter (7nm) & ASI294MC Pro camera and got a more pronounced central area.

I've also included the Oiii stack from this session, stretched and nothing else done to it.

Interesting. This is the blue channel from our OSC camera.

I'd probably vote for reflection, but who knows?

It could well be reflection, and the difference in my images is 7nm Duo-band verses 4nm Oiii filters.
