M33 -- just goofing around

Posted By Greg Bradley
Fantastic Tom.

That is one of the better Pinwheel's I have seen. It often just looks like cotton candy with no real definition.

Yours looks like a galaxy.

Boy, you have your setup humming and you know how to use it to good effect.
What you need now is to plan a trip to Aussie to my dark site to complete the astro-imaging journey to image those targets you don't get in the US!

You know you deserve it!

NGC 253

Hi Louie,

A couple of comments.

Sculptor is a dusty galaxy and the surrounds should be more brown and the centre glowing yellow. It also has a bluish tinge around the ring.

The stars seem a bit bloated to me for an APO refractor. I suspect IR bloat. Perhaps try using a Baader UV/IR block filter. Also double check your focus to make sure it is as sharp as you can get.

You have a fairly highly magnified image scale there but that 105 F6.2 TMB lens should be sharper than that, something is affecting it or the focus is off. I think Warren used a Baader UV/IR block filter with his SXV H9C so perhaps you can ask him how much difference it makes.

M33 after more data -- It looks like fireworks!!

Amazing Tom.

You must be one of the best imagers on the planet.

Not another one of these !

Nice shot Louie. The core is full of detail.

By the way I'd love to hear a review of your WO105ED. Is that the TMB 105/F6.2 triplet lens? I hear that's a beauty. My WO 80mm triplet fluorite was nice but the WO body put the lens out of collimation and I had to shim the focuser to counteract. I have heard of others doing that. Have you had that trouble or is the collimation spot on?

Here is a 2nd shot of the LMC. This one was taken the night before the last one. I used a modified Canon 20D and also the FSQ.

This one is only 10 x 2 minutes for a total of 20 minutes.

Wow, what an unusual image. It really shows up the Trapezium well.

Great little scope. Like a mini FSQ.
Nice colour.

M20 last night

Posted By Greg Bradley
Make sure you label each sub exposure as it is really easy to get lost afterwards. For example: M20 1x1 -20C red. Then later you know what darks and flats to apply and which go with which.

Otherwise you can be trying to make a RGB image out of GBR and you don't know.

It looks a bit like you may have your colours mixed up.
