Keyhole repro

[multiweb (Marc)]

This is a pic I took end of March with the FSQ and the Baader FFC x 3. I wasn't entirely happy with the process. I teased a little more details and I'm happier with the contrast and level of details of this one.

I have a HD version here [1920x1403 - 1.1MB]
and a 70% version here. [2320x1695 - 1.4MB]

Will revisit with the C11 which should frame just the keyhole area nicely with better resolution. Enjoy.

Pretty good for a 4" scope Marc

Lots of sharpness there Marc. Nice tight stars.

Beautiful.

Is the Baader FFC like a barlow? So, effectively, you were imaging at 1590mm focal length?

Thanks guys. That'll do a nice scaffold for a higher res mosaic.

Thanks H. Yeah x3 so 1590mm. Image scale is 0.7asp and fov 42'x30'.

How much is one of these devices worth?

Check it here. Still cheaper and better quality than an assortment of powermates or barlows. That's why I bought it in the first place. All in one. x3 to x8 with no aberrations what so ever and no light scattering from UV to IR.

Marc, you got a lot of detail in your image. I like it a lot!

The only thing I would change is to relax star reduction - dark rings around stars is the only aspect I can think of that could potentially be improved.

Well done!

Yeah I got a little lazy with my star mask. I didn't reduce them but the deconv algo must have darkened and ringed some of them. I usually blur them with the FSQ and make them a little fuzzier otherwise they look too tight and burnt.

Thanks for the link, Marc!

I think I will hold off. Other potential pending purchase taking precedence.

That's very cool Marc. Depth and contrast are very good to my eyes. Easily look at this for a long time.

Thanks Trevor. I did some panels with the C11 last night. There are some mushroom shaped nebulae around the keyhole.

Thank you Leo.

Cool. I look forward to seeing them.

That's a stunner Marc. Really good contrast and detail you have achieved.

[RickS (Rick)]

Very crisp, Marc!

Thanks guys. I did a longer FL shot on Friday but the seeing wasn't as good. It was coming and going.

I also had issues with Eta blooming on 180s exposures. I wasn't sure if it's meant to saturate the CCD with that sub length.
Even 1s/5s exposures on the homunculus would bloom.
