Ic410 The Tadpoles - Hst

[strutsinaction]

Hi

Here's my recent narrowband capture of IC410, rendered using the Hubble palette and cropped.

Target details:

IC410 is a HII emission nebula in the constellation of Auriga. Commonly known as the Tadpole Nebula for the small 'tadpole-like' structures of dense, cooler gas that are being shaped by the intense radiation from the hot stars of the young open cluster NGC 1893. It is approximately 12000 light years way and 300 light years across. The 'tadpoles' are approximately 10 light years in length.

Capture and processing details:

Ha 30x600s

OIII 15x600s

SII 15x600s

Bias + Flats

Avalon Linear + FSQ85 + QSI690 + SGPro

Processed with PixInsight + PS.

Thanks for looking!

Good image this one, and nicely processed. What you would expect from your excellent kit!

You've done amazingly well to get 10 hours of data here, and the detail/resolution benefit a lot from this - lovely palette and processing also.

Chris/Martin - thanks for the positive feedback, much appreciated!

I'm now taking much more care over my focussing, and regularly refocussing as the subs roll in. In the past I've neglected to do this, giving rise to elongated stars in the corners, particularly the right hand corner. I thought this may have been due to sensor tilt or a Tak collimation issue but it turns out it was simply poor focussing 

My QSI690 has also had the 'Sony glow' fix applied which has improved my NB subs. No more darks!

I follow Bill Snyder's approach to rendering the HST palette:

Excellent image John.  Delicate processing and tone balance in the HST palette.

As you say, focus is one of the key elements in a cracking image and you've nailed it here.

Thanks, Barry! Regarding focusing - maybe I need to invest in a Lakeside motor focuser an automate the focusing via SGPro. I see that you have the Tak 85. Do you use a motor focuser?

[Barry-Wilson]

Yes I do. I wouldn't be without it, works seamlessly with SGP and its AF process. It's a must if you want to automate your imaging.

Another thumbs-up for the Lakeside motor focuser, I've had mine for about 3 years now and it's transformed the accuracy of my focusing. The other bonus of course is that the Lakeside is fully compatible with all the software packages to automate the focusing, I use mine with Focusmax (via Maxim) and CCD Commander.

Very nice image. Lots of interesting detail.

Thanks, Laudrop! Yes, an interesting nebula that's for sure.

Martin: So, another thumbs up for the Lakeside. I think Sara Wager also uses the same focuser for her Tak. To be investigatedfurther me thinks!
