I think my next bit of astro gear should be a van in which to live in the desert for a while and work with dark dry sky.

And what to do for May...wide fields of the Milky Way would be good☺
Maybe the Cats Paw as it should be a nice object for many local lengths...
And we need more raw beginners so if you are watching join in next month.

This is interesting.

The first image (see above a few posts) of NGC2070 is comprised of:

130 subs. 120s Gain = 70

The 2nd image 30 subs at the same settings.

Both using the exact same processing.

From my study, there is no discernable difference.

Attached is the 30 sub version.

And thanx Alex for encouragement

They are both really, really excellent Peter & Alex.
A nice way to top off this month's object.

Alex's suggestion of the cat's Paw for the next month is a good one.

I like the idea of the Cats Paw, should be a good target for even shortish focal lengths.

Also, the whole area presents a great target for beginners with tripod mounted cameras.

This might be the first target with my new Evostar 72ed that coming mid may.

Now if only the weather could come to the party and not mess up our nights fun than that would be great.

Well done Jeff

Once again the camera has caught the overall blue caste.

Finding, focusing and framing targets can be a real challenge not to mention the nightmare of processing!

And don't forget the darks, flats and bias images.

Imaging the 'cats paw' for the first time will be fun!

Thanks Peter, I know the focus is a bit soft and I do minimal processing as I get bored spending hours on images trying to eke out detail, colour , contrast etc.
There are, (all are ) many excellent images presented for this LMC month, can't but not be impressed.
Hopefully will get the clear skies etc to do the Catspaw or I could sneak in an image I took last year, is that cheating, are there any rules or criteria involved.

Hi Jeff
Thank you for joining in a posting a very respectable image.
And I look forward to see what you can do with the Cats Paw.
May I ask how was the camera mounted?
Alex

Hi Alex
Thanks for your comments, I have been following your astrophoto travels and enjoy your observations and insights, most entertaining.
The mount used for that image was a stock standard EQ5, non Go To but dual axis drives, polar aligned using the inbuilt polar scope. Camera was attached to a ball head, attached to an vixen style dovetail. I have found over the years that for widefield astrophotos the mount tracks well enough for up to 10 min. subs though now I usually do 30 / 60 sesc. subs depending on the target.

Hi Jeff
I am happy I am entertaining you it is my hope that I can encourage and uplift others.

I was forced to go for short subs because of the poor polar align...I cant see any stars through my polar scopes...and yes I turned the mount around and took the lens cap off☺...anyways I cant manage bending down unfortunately.
Alex
