There are also a few faint galaxies visible in the background.

A fine image there Bert - fun to swim around in too. Nice one!

Cheers, Marcus

Nice widefield Bert ... haven't seen these two together before.

[Jay-qu]

Just wow.

I love your mosaics

[telecasterguru (Frank)]

Very nice wide picture.

[Tamtarn]

Nice perspective Bert. Interestingly there is more size difference between the two than we had imagined

[Craig_L]

Yes, great to see the perspective and size difference in the same frame.

[h0ughy (David)]

wow i am blown away with the immensity within that image. simply breathtaking

[Starkler (Geoff)]

Top marks for presenting an original perspective.

[Liz]

Wow, that is a wonderful shot Bert, well done .... very cool pic

[gregbradley]

Wow, I like it. Very creative framing.

Greg.

a very fine shot..so many background galaxies

[peeb61 (Paul)]

Well done Bert!
Just love these widefield shots.

Great work.

Another nice job Bert.

I remember doing similar B&W fields with A Pentax 300mm and 95mm lens and 6X7 camera back in the mid 80's.

Great FOV

What a picture!! Just love the clarity and perspective.

I've often had a look at these two but didn't realise they were this close together.

Well done Bert.

Thanks for the comments all. Here is a high resolution animated gif of the image and map made with Star Atlas Pro with an image for all you galaxy hunters. I used Registar to align the two.

I do wide fields to give me a better mental picture of the relationships or context between objects that are generally imaged at long focal lengths.

One very fortunate consequence of using the fridge is that focus does not change with even major changes in ambient temperature. The whole optical train effectively is kept at a constant temperature to within 0.1C once equilibrium has been reached. In fact if I take a sequence of images while the fridge is cooling you can watch the stars come into perfect focus if the set temperature is the same as the previous imaging run.

Lovely work Bert resulting in a superb image.

[WadeH (Wade)]

The GIF file is fantastic Bert. It must have taken you ages to find all of those background galaxies!! Please keep these widefields comming.

[avandonk]

Wade the map comes from Star Atlas Pro. I would be lost without it!

For those of you who want a better look, here is an upsized image to 7k pixels wide and enhanced with RL deconvolution in IP at a high jpg quality (as if there is such a thing!). It unfortunately shows every blemish but it is clearer at high mag.

Great object pairing not often seen. Nice one Bert.
